目前,多层砖房在我国占整个民用建筑的85%以上,而且在今后相当长的时间内仍将是我国主要的建筑结构形式之一。随着大批住宅的兴建,城市为了节约用地而增加住宅层数的现象比较普遍。以沈阳兴建的砖混结构住宅为例,7层的楼房已屡见不鲜,8层的也逐渐增多。因此,确定在地震区采用加设构造柱的办法增加多层砖房的允许建造高度,在技术上和经济上都具有重要意义。 At present, multi-storey brick houses account for more than 85% of all civil buildings in China, and will remain one of the major architectural forms in China for a long time to come. With the construction of a large number of residential buildings, it is common for cities to increase the number of residential buildings in order to save land. Taking the brick-concrete structure residential building built in Shenyang as an example, the 7-storey building has been frequently seen, and the 8-storey building has gradually increased. Therefore, it is technically and economically significant to increase the permitted building height of multi-storey brick houses by adding structural columns to the seismic zone.
