近年来我国高层建筑迅速发展,钢筋混凝土墙体建筑越来越多,普遍要求新规范中反应这方面的内容。这种墙体既承受水平和垂直荷载,又兼作隔断或围护墙用。新规范中,墙式结构房屋的伸缩缝最大间距拟定为: 装配式:室内70米;露天50米。现浇式:室内50米;露天35米。这一规定是根据以下几个城市的调查结果提出的,即:北京64栋,广州8栋,深圳10栋,天津5栋,共87栋。这些墙式结构房屋分布在不同地区,在一定程度上反应了气温、设计和施工条件,以及使用材料的差别。这些房屋中,装配式结构有2栋(房屋长度为79.8米和50.2米),现浇式结构有85
In recent years, the rapid development of high-rise buildings in China, more and more reinforced concrete wall construction, the general requirements of the new specification to reflect this aspect. This type of wall is subject to both horizontal and vertical loads and serves as a partition or wall. In the new specification, the maximum spacing of expansion joints for wall-type structures is to be: Assembled: 70 meters indoors; 50 meters outdoors. Cast-in-place: Indoor 50 meters; open air 35 meters. This provision is based on the following survey results of several cities, namely: 64 in Beijing, 8 in Guangzhou, 10 in Shenzhen, and 5 in Tianjin, for a total of 87 buildings. These wall-structure houses are located in different areas and reflect to some extent the differences in temperature, design and construction conditions, and the use of materials. Among these houses, there are 2 prefabricated structures (house length is 79.8m and 50.2m), cast-in-place structure has 85
