2010年1月12日发生在伊斯帕尼奥拉岛的地震摧毁了海地。由于不受控制的施工、低劣的材料质量和缺乏严格的工程设计，破坏是广泛的。事后的调查暴露了这些方面的严重缺陷。海地的住宅建筑通常由业主建造，他们可能有也可能没有技能或资源来建造地震安全的结构。很少有建筑物是由工程专业人员设计的，也很少有建筑物经过质量检查。两种最常见的建筑材料是砌块和钢筋混凝土。从海地运来的砌块、混凝土圆柱体和钢筋在美国进行了测试。混凝土和砌体的强度和质量都很低。钢样品显示出预期的强度特性，其中一些样品由于弯曲而具有降低的延展性。建筑性能通过勘察照片和勘察小组成员检查的结构案例研究来证明。
The earthquake that shook Hispaniola on 12 January 2010 devastated Haiti. The damage was widespread due to uncontrolled construction, poor material quality, and lack of rigorous engineering design. Post-event reconnaissance has brought to light serious deficiencies in these areas. Residential buildings in Haiti are typically constructed by their owners, who may or may not have the skills or resources to build a structure that is earthquake-safe. Few structures are designed by engineering professionals or are inspected for quality of construction. The two most common construction materials are masonry block and reinforced concrete. Masonry blocks, concrete cylinders, and reinforcing steel were taken from Haiti and tested in the United States. The concrete and masonry were shown to be of low strength and quality. The steel samples show expected strength properties with some specimens having reduced ductility due to bending. Building performance is demonstrated by reconnaissance photographs and case studies of the structures inspected by reconnaissance team members.
