大模板现浇钢筋混凝土结构体系具有整体性好、抗震能力高,自重轻、材料省等优点。大模板经过改进,出现了隧道模、台模、飞模以后,更加快了工程进度,节约了劳动力,很有发展前途。这种体系,近年来建造较多,尤以北京、天津、唐山一带比较集中。但据调查,存在墙体开裂的现象比较普遍,个别建筑物裂缝还相当严重,不仅住户反映强烈,也引起了工程界的注意。既然大模板形成的剪力墙体系具有良好的结构性能,拥有较强的抗水平荷载、垂直荷载和地 The large-formwork cast-in-place reinforced concrete structural system has the advantages of good integrity, high seismic resistance, light weight, and material saving. After the big template has been improved, tunnel models, table models and flying models have emerged, which has accelerated the progress of the project, saved labor, and has promising future. This kind of system has been built in recent years, especially in Beijing, Tianjin, and Tangshan. However, according to the survey, the phenomenon of wall cracking is common, and the cracks in individual buildings are still quite serious. Not only do households have a strong response, but they also attracted the attention of the engineering community. Since the large-formed shear wall system has good structural properties, it has strong resistance to horizontal loads, vertical loads, and ground
