THANK YOU ! EARTHQUAKE DAMAGE REPAIR May 2020 Repairs of Damaged Buildings REPAIR AND SEISMIC STRENGTHENING OF BUILDINGS • Repair and seismic strengthening of damaged structures is important in order to restore the use of structures damaged in an earthquake, and guarantee the safety of residents or users. • Although repairs may provide some local resiliency to elements damaged in an earthquake, they are not seismic upgrades. DIFFERENCE BETWEEN REPAIR AND SEISMIC STRENGTHENING OF BUILDINGS. • Seismic strengthening requires an analysis of the existing building. But repair is based on guideline details. • Seismic strengthening is designed for the entire building to address the structural deficiencies of the lateral force resisting system. But repair is only applied to damaged elements and does not address other deficiencies. DIFFERENCE BETWEEN REPAIR AND SEISMIC STRENGTHENING OF BUILDINGS (CONT.) • Strengthening is typically implemented prior to an earthquake to reduce the risk of loss of life, injury, and major structural damage or collapse. DIFFERENCE BETWEEN REPAIR AND SEISMIC STRENGTHENING OF BUILDINGS (CONT.) • Repairs are implemented after an earthquake and may add additional resiliency to the elements that were damaged, but the building will most likely experience similar damage in future earthquakes. REPAIR • R epairs are applied only to the damaged elements of the building. • The goal of repair is to bring the building back to the original condition prior to the seismic event. REPAIR ( CONT .) • Repairs are usually made following a natural disaster (earthquake and hurricane most common case in Haiti). • A rapid and detailed assessment of the damage is necessary prior to identifying the repair type. REPAIR ( CONT .) • For this program, the repair methods that will be illustrated below are applicable for residential and commercial buildings not exceeding two levels. REPAIR (CONT.) SEISMIC STRENGTHENING • Seismic strengthening is designed for the entire building to address the structural deficiencies of the lateral force resisting system. • Strengthening can be done prior to an earthquake, or after an earthquake, along with repairs or reconstruction of damaged elements . SEISMIC STRENGTHENING ( CONT .) • Seismic strengthening is typically applied to a large industrial or commercial building, hospital, school, public or government buildings. SEISMIC STRENGTHENING AFTER EVENT Natural disaster Structural Damage Assessment Detailed Damage and Repair Assessments Create as - built plan and collect all structural information Seismic Strengthening Design SEISMIC STRENGTHENING PRIOR TO EVENT SCHEMATIC REPAIRS DESIGN BASED ON:  Engineering principals of Reinforced Concrete Masonry  ASTM STP 1180 testing performed  This testing was done on unreinforced block masonry walls similar to what is used in Haiti and provides energy absorption characteristics with increased shear capacity with joint reinforcement  300% capacity increase ASSESSMENT AND REPAIR This training is intended for engineers who ensure quality control of the repair of damaged structures in the following cases: • Residential structures one to two levels. • Residential structures tagged green, yellow or red (little damage ). • R esidential structures requiring simple technical solutions. ASSESSMENT AND REPAIR (CONT.) • Load - bearing wall structures with lightweight roofing systems. • Structures whose overall repair costs are within acceptable limits.  Repair damaged structure back to pre - earthquake condition, or better.  Do not provide significantly more strength or stiffness in one area of the building during repair  Provide enhancements in ductility (energy absorption) where possible REPAIR GUIDELINE LIMITED TO: • One and two story confined concrete masonry buildings • Concrete or wood roof • Yellow tagged structures o Minimal damage leading to a more efficient repair • Some red tagged Structures o Some have limited damage which causes the ‘’ Red tag’’ RAPID DAMAGE ASSESSMENT • After a natural disaster rapid damage assessment evaluations will be conducted for all buildings . • The evaluations will be conducted by ATC 20 modified version for Haiti • Safety Evaluation of damages • Tagging of all buildings ENGINEERS ARE TRAINED TO DO A REPAIR ENGINEERING ASSESSMENT • On site engineering review of structures • Identification of repair methods • Measurement of repair quantities and schedule • Post - processing data to quantify material and repair costs TYPICAL EARTHQUAKE DAMAGE A1 DIAGONAL SHEAR CRACK IN CONCRETE MASONRY WALL. (X - CRACK) REPAIR A1 Shear X Crack = Wall Replacement  Earthquake forces have caused shear failure  The remaining capacity is limited.  The repair provides for additional capacity with steel reinforcing and better quality construction in masonry, mortar and concrete. B1 AND B2 Diagonal shear crack in concrete masonry wall with a window. • B1 is for opening without a Lintel. • B2 is for opening inclusive of a Lintel. • B1 is for opening without a Lintel • B2 is for opening inclusive of a Lintel. REPAIR B1 Shear X Crack w/ window = Wall Replacement • Earthquake forces have been absorbed into the masonry wall piers and the piers have fractured due to the forces. • The remaining load carrying capacity is limited. • The repair provides for additional capacity with steel reinforcing and better quality construction in masonry, mortar and concrete. REPAIR B2 Shear X Crack w/ window = Wall Replacement • Earthquake forces have been absorbed into the masonry wall piers and the piers have fractured due to the forces. • The remaining load carrying capacity is limited. • The repair provides for additional capacity with steel reinforcing and better quality construction in masonry, mortar and concrete. C1 Out of plane failure of wall. REPAIR C1 Dislodged Wall = Wall Replacement • Earthquake forces have moved the wall – out of plane. The wall is now ineffective to resist new earthquake forces. • The repair provides for additional capacity with steel reinforcing and better quality construction in masonry, mortar and concrete. D1 Lintel failure above door or window. REPAIR D1 - LINTEL REPAIR - CRACKED LINTELS ABOVE DOORS/WINDOWS • Earthquake forces have moved the walls. The window lintel acts as a linking element and absorbs the earthquake forces. • The repair provides for additional capacity in the lintel and better quality construction . REPAIR D1 - LINTEL REPAIR E1 AND E2 Isolated wall failures due to pounding of adjacent walls or out of plane movement, due to lack of adequate connection from roof to wall. E1 AND E2 (CONT.) Isolated wall failures due to pounding of adjacent walls or out of plane movement. REPAIRS E1 - WALL FAILURE E1 - Pounding at Perpendicular Walls REPAIRS E2 - WALL FAILURE E2 - Out of plane for Wood Roof - Lack of connection WOOD ROOF CONNECTION Wood Roof Concerns: 1. Provide wall connections with new chainage where damaged 2. Chainage with reinforced masonry or concrete 3. Add new roof anchorage: • Bent vertical bar from wall • New #3 wire hook • New #3 rebar tie F1 Minor cracking in Plaster or Masonry – Non - Structural. REPAIR F1 MINOR CRACKING IN CMU As buildings move the non - structural items will take load and crack due to the movement. These cracks are not considered structural in nature but are earthquake damage and should be properly repaired. G1  Concrete cover on column has spalled.  Column inner core remains intact. REPAIR G1 SPALLED COLUMN Due to the movement of the structure and the general lack of a restraining connection from columns to beams in the slabs. The tops of columns can be subjected to loss of cover concrete on the reinforcement. Providing a replacement to this cover will provide the necessary protection for the reinforcement. H1 AND H2 Concrete column rupture and replacement. REPAIRS H1 AND H2 CONCRETE COLUMN RUPTURE – TOP AND BOTTOM  Condition occurs at Red tagged houses.  Movement of the column and lack of proper reinforcement confinement allows the concrete to rupture. ENHANCED MASONRY WORK Repair Construction Provides for new techniques  New masonry techniques  Layout  Mortar placement  Material Mix Consistency  Working existing blocks:  H - blocks for Reinforcement  Hollow Blocks  Horizontal Reinforcement  Vertical Renforcement  Grouted masonry CONSTRUCTION SEQUENCING REPAIR A1, B1, B2, AND C1 1.

The quality control engineers’ main purpose is to minimize the chance of defects before the project delivery to the owner or his consultancy. QUALITY CONTROL (CONT.) Controlling quality means monitoring if the work practices are going as planned or not, examining the quality of the current construction tasks, and provide daily reports for all sites in construction. Also, the main goal is to ensure that the construction meets the standards specified at the start of the project. THANK YOU ! ROOF STRUCTURE REINFORCEMENT SOLUTIONS FOR HURRICANE May 2020 • Haiti is prone to cyclones, hurricanes and tropical storms • Very high wind speeds and pressures • Engineered systems prevent costly and dangerous damage ROOF TO WALL CONNECTIONS • Critical Connection • Provide safety and limit damage or collapse due to hurricane and tropical storms ROOF TIE DOWN SYSTEM MOST COMMON IN HAITI CONSISTS OF CONCRETE BLOCK OR ROCKS • During a wind storm, the building must withstand a horizontal wind force on the walls and windows and an upward pulling force at the roof. • These forces can reach 300 kg per square meter and sometimes more during a cyclone. • To withstand a hurricane, the structure and the roof must be properly constructed. ROOF CONSTRUCTION QUALITY • In the case of a building covered by a light roof or concrete slab, they will become dislodged and removed or collapsed if the construction quality is poor. • For the roof slab poor quality can result if the concrete is made with white sand with salts instead of silica sand. Reinforcements will be visible on the surface in a few years due to water intrusion, reinforcing steel deterioration and concrete efflorescence. ROOF CONSTRUCTION QUALITY (CONT.) • The poor quality of the light roof is evident a. If the wood framing has termite damage or dry - rot or is of insufficient cross - section. b. If the wood framing is fixed to the wall by inadequate connection. c. If the sheet metal roof panels are rusted, or if the sheet metal roof panels are insufficiently fixed by nails or screws. LIGHT ROOF FRAME • The dimensions of the roof frame must be calculated to resist wind loads according to ASCE 7 (16). • For common building practice in Haiti, the purlin and rafter system is an economical solution because t he sheet metal roofing is attached directly to these purlins and it is not necessary to add sheet metal cleats. LIGHT ROOF FRAME (CONT.) • The spacing of the purlins, which receive the sheet metal roofing directly, must not exceed 60 cm. • The purlins shall be joined to the rafters and the rafters shall be connected to the bond beam or reinforced wall with positive connections designed to resist wind uplift loads. - La charpente : les dimensions de la charpente doivent être calculées pour une bonne résistance au vent suivant ASCE 7(05). Pour les bâtiments courants de un à deux niveaux, la solution de charpente par pannes est une solution économique car les tôles sont alors fixées di rectement sur ces pannes et il n’est pas nécessaire d’ajouter des tasseaux à tôles. L’écartement des pannes, qui reçoivent directement les tôles de couverture, ne doit pas excéder 60 cm. Les jonctions des pannes doivent se faire sur les appuis Dessin 76 : Dessin 77 : Dimensions correctes jonctions sur les appuis À faire Pannes jonctions hors des appuis À ne pas faire Span : 4.8m Too long Spacing : 1.7m Too big Span : 3m max Spacing: 0.6m max RAFTER AND PURLIN SPACING INCORRECT RAFTER OR PURLIN OVERLAP Simply nailed junction second choice wood with knots CORRECT RAFTER OR PURLIN OVERLAP RAFTER OR PURLIN CONNECTION AT WALL For a light roof structure covered with sheet metal roofing supporting by purlins and rafters, the treated wooden rafters shall be fixed on the bond beam a. By Galvanized steel brackets or hooves, screws, brackets and bolts, which require electrical equipment to install, b. Or by a 2.5 mm thick and 2.5 cm wide galvanized metal clip link fixed and nailed in the bond beam, c. Or by a 3/8’’ steel anchored in the bond beam. Incorrect Fixation Correct Fixation 3/8’’ diameter steel anchored at Bond beam 5cm TYP. 20cm Bond Beam RAFTER Sheet metal 3/8’’ steel CMU Wall Correct Fixation • Galvanized clip and strap anchored at bond beam • Galvanized steel brackets installed at bond beam top surface SHEET METAL SCREW SPACING • For corrugated sheet metal, the interval between the screws line is 3 waves or flutes. The spacing must be 20 cm center to center between the lines. • For a trapezoidal sheet metal provide the screws at each flute. The spacing longwise must be 20 cm center to center between each line. • Joining (stitching) sheets longwise every 30cm. SCREW SPACING AT CORRUGATED SHEET METAL SCREW SPACING AT TRAPEZOIDAL SHEET METAL JOINING (STITCHING) SHEETS ROOF ACCESSORIES They will be made of sheet metal of the same quality as the roofing sheets. The ridge capping shall be connected to the ridge purlins in the case of a roof with an inclined shape. Screws shall be spaced at 30 cm on center along the ridge purlin. GALVANIZED RIDGE CAPPING Example of a light roof fixed by a sheet metal screws or lag bolts. THANK YOU !

STRUCTURAL DRAWINGS May 2020 STRUCTURAL CONSTRUCTION DOCUMENTS Structural construction documents is a set of plans and specifications that indicates how a building structure will be built. It includes • F oundation plan and dimensions • Framing plans and details • Moment frame, braced frame, or shear wall elevations • W all sections STRUCTURAL CONSTRUCTION DOCUMENTS (CONT.) • Structural drawings are generally prepared by registered professional engineers, and based on information provided by architectural drawings. • The structural drawings are primarily concerned with the load - carrying members of a structure. They outline the dimension and types of materials to be used, as well as the general demands for connections. STRUCTURAL CONSTRUCTION DOCUMENTS (CONT.) • The structural drawings communicate the design of the building’s structure to the building authority for review. • Structural drawings are also included with a proposed building's contract documents, which guide contractors in detailing, fabricating, and installing parts of the structure. STRUCTURAL CONSTRUCTION DOCUMENTS (CONT.) Note: The structural drawings do not address architectural or MEP details such as • Surface finishes • Partition walls or, • Mechanica
