住宅、旅馆类建筑的首层,常需布置商店、餐厅、会议室。目前我国采用的大模板剪力墙结构,大多为2.70～3.90米小开间,且全部剪力墙落地,不能在首层形成大空间。这样,便造成规划上另行布置大量附属建筑,街景、立面单调,不能满足城市规划和建筑使用多方面的要求。研究首层大空间的剪力墙结构,已成为完善与进一步推广剪力墙结构的一项重要内容。
On the first floor of residential and hotel-type buildings, shops, restaurants, and meeting rooms are often required. At present, the large formwork shear wall structures used in China are mostly 2.70 to 3.90 meters in size, and all the shear walls fall to the ground and cannot form a large space on the first floor. In this way, a large number of outbuildings are planned to be laid out separately, and the streetscape and facade are monotonous, which cannot meet the requirements of various aspects of urban planning and construction. Studying the shear wall structure in the first floor of the large space has become an important part of improving and further promoting the shear wall structure.
