【摘要】 根据玉树大地震现场考察结果,系统地介绍了砌体结构房屋在房屋结构体系、房屋墙体、圈梁和构造柱、楼梯、墙角、预制板楼盖、屋盖及突出屋面的屋顶间等附属构件的主要震害特征,为提高此类房屋防震减灾能力,提出以下几点建议:(1)该地区限用底框结构,彻底改造生土房屋。(2)建筑平面应规则、立面无凸凹设计、抗震构造措施合理。(3)砌体结构应设圈梁和抗震构造柱。(4)坡屋顶房屋的屋架应与顶层圈梁可靠连接,檩条或屋面板应与墙及屋架可靠连接。(5)预制阳台应与圈梁和楼板的现浇板带可靠连接。(6)采用现浇混凝土楼板,若采用预制空心板,应该加强连接。(7)楼梯作为主要的交通和逃生通道,应该加强其抗震构造措施,提高该部分的抗震承载力。更多还原
