一、规程制定的背景 1.国外标准现状早在40年代末、50年代初,西方工业发达国家如美国、英国等就制定了建筑玻璃的相关标准。随着时代的发展,特别是到了70年代,高层建筑的大量兴起,大面积、大板面玻璃的广泛使用,使设计环境发生了很大的变化,玻璃应用面临更加苛刻的条件,伴随着玻璃失效和破损带来的严重后 First, the rules of the background of the development 1. The status quo of foreign standards As early as the late 40s, early 50s, Western industrialized countries such as the United States, Britain and other developed architectural glass standards. With the development of the times, especially in the 1970s, the rise of high-rise buildings in large numbers and the extensive use of large-area and large slab glass have greatly changed the design environment. Glass applications are facing even more harsh conditions, accompanied by glass After the failure and damage brought serious
