为了加强房屋的整体刚度,提高多层砖砌体结构的抗震能力,GBJ11—89条文说明中明确指出,钢筋混凝土构造柱在多层砖砌体结构中的应用,是根据唐山地震的经验和大量试验研究,得到比较一致的结论。构造柱能提高砌体的抗剪强度10%—30％左右,提高幅度于墙体的高厚比,竖向压力和开洞情况有关,构造柱主要是对砌体起约束作用,使之具有较高的变形承受能力。构造柱应设置在震害较重连接构造比较薄弱和应力易于集中的部位。圈梁能增强房屋的整体性,提高房屋的抗震能力,是抗震的有效措施。因此,在多
In order to strengthen the overall rigidity of the house and improve the seismic resistance of multi-story brick masonry structures, the GBJ11-89 article specifies that the application of reinforced concrete structural columns in multi-storey brick masonry structures is based on the Tangshan earthquake experience and a large number of Experimental study, a more consistent conclusion. The structural columns can improve the shear strength of masonry by about 10% to 30%, and increase the ratio of height to thickness of the masonry wall. The vertical pressure is related to the opening conditions. The structural column is mainly responsible for the masonry, so that it can have High deformation tolerance. The structural column should be located in a place where the damage is severe and the stress is easily concentrated. The circling beams can enhance the integrity of houses and improve the earthquake resistance of houses, which is an effective measure for earthquake resistance. Therefore, in many
