问题 单项选择题

下列关于砌体房屋抗震计算的论述不正确的是()。

A.多层砌体房屋抗震计算,可采用底部剪力法

B.多层砌体房屋,可只选择承载面积较大或竖向应力较小的墙段进行截面抗剪验算

C.进行地震剪力分配和截面验算时,墙段的层间抗侧力等效刚度可只考虑剪切变形

D.各类砌体沿阶梯形截面破坏的抗剪强度应采用fVE

答案

参考答案:C

解析:根据《建筑抗震设计规范》(GB50011—2010)第7.2.3条,进行地震剪力分配和截面验算时,砌体墙段的层间等效侧向刚度应按下列原则确定:刚度的计算应计及高宽比的影响。高宽比小于1时,可只计算剪切变形;高宽比不大于4且不小于1时,应同时计算弯曲和剪切变形;高宽比大于4时,等效侧向刚度可取0.0。
