题25~28:某12层现浇钢筋混凝土剪力墙结构住宅楼,各层结构平面布置如图1-22所示,质量和刚度沿竖向分布均匀,房屋高度为34.0m。首层层高为3.2m,其他各层层高均为2.8m。该房屋为丙类建筑,抗震设防烈度为7度,其设计基本地震加速度为0.15g,建于Ⅲ类建筑场地,设计地震分组为第一组。
该房屋基本风压w0=0.55kN/m2,34.0m高度处的风振系数βz=1.60,风压高度变化系数声μz=1.55。假设风荷载沿高度呈倒三角形分布,地面处风荷载标准值为0.0kN/m2。 试问,在图1-22所示方向的风荷载作用下,结构基底剪力标准值(kN)应与下列何项数值最为接近? 提示:按《建筑结构荷载规范》GB
A. 610
B. 725
C. 1040
D. 1450
