Best Practices for Construction of Small Confined Masonry Buildings
Summary — This document provides best practices for masons involved in constructing small residential buildings in Haiti. It focuses on reinforced masonry techniques to enhance earthquake and hurricane resistance, specifically for buildings with a maximum of two stories. The guide covers site selection, material quality, and construction methods for walls, columns, and concrete elements.
Key Findings
- Build on flat or gently sloping land to avoid landslides.
- Use high-quality materials like washed sand and crushed gravel.
- Confine masonry walls with tie beams at the top and extremities.
- Ensure concrete blocks have a minimum compressive strength of 10 MPA.
- Maintain consistent spacing of stirrups along the column height.
Full Description
This document outlines best practices for the construction of small, confined masonry buildings, specifically tailored for masons working on residential projects in Haiti. It emphasizes techniques to improve the building's resistance to earthquakes and hurricanes. The guide covers various aspects of construction, including site selection, material quality control (e.g., testing concrete block strength), and detailed instructions for constructing walls, columns, and concrete elements. It provides guidance on proper mixing ratios for concrete, mortar, and grout, as well as best practices for reinforcing structures to withstand seismic activity and high winds. The document is intended to support USAID/BHA interventions and enhance resilience in Haiti.
