有关结构抗震的资料,一些建设部门先后颁布了多种规范和图集,但这些规范和图集对某个同样问题的规定却不统一,现仅提出几个在设计和施工中经常遇到的问题。一、墙体拉结筋的设置现行《建筑抗震设计规范》(GBJ11-89)第5.3.2条规定:构造柱应沿墙高每隔500mm设2φ6拉结钢筋,每边伸入墙内不宜小于1m。现以8度抗震设防地区、外墙
Regarding the structural anti-seismic data, some construction departments have successively issued a variety of specifications and atlases, but these specifications and atlases do not provide a uniform definition of the same problem. Now only a few are frequently encountered in design and construction. problem. First, the setting of the wall pull ribs The current “Building Seismic Design Code” (GBJ11-89) Section 5.3.2 stipulates that: the structural column should be set along the wall height every 500mm 2φ6 pull knot reinforcement, each side into the wall is not appropriate Less than 1m. 8 degree seismic fortification area and exterior wall
