对砖石墙建筑的建造方法及其在严重风暴中的性能进行了检查。特别强调的是使用无钢筋混凝土砌块墙和轻型屋顶的低层建筑，这些建筑遭受了大部分的风害。结果表明，传统的建造，非工程建筑物已成为近年来由于减少内墙的数量和降低屋顶重量的风敏感。关于墙高厚比和屋顶锚固的经验设计程序没有改变，以反映这种增加的敏感性，使许多现代非工程建筑物的抗风能力不足。由于相同的经验设计规则通常用于确定墙壁和屋顶锚定件的尺寸，因此，按比例设计的结构通常与传统建造的结构具有相似的结构形式。这些建筑物中较长的屋顶跨度使它们对风扬荷载更加敏感，并受到风荷载的影响。
An examination has been made of the methods of construction of masonry‐walled buildings, and their performance in severe windstorms. Particular emphasis was placed on low‐rise buildings using unreinforced concrete block walls and light roofs, which suffer the majority of wind damage. It is shown that traditionally built, nonengineered buildings have become more wind sensitive in recent years as the result of a reduction in the number of internal walls and a lowering of roof weights. Empirical design procedures regarding wall height‐to‐thickness ratios and roof anchorage have not changed to reflect this increased sensitivity, leaving many modern, nonengineered buildings with insufficient wind resistance. Professionally designed structures often have a similar structural form to traditionally built structures, since the same empirical design rules are often used to size walls and roof anchors. The longer roof spans in these buildings render them even more sensitive to wind uplift loads, and subject to progr...
