X方向最小刚度比: 1.0000(第 8层第 1塔)
Y方向最小刚度比: 1.0000(第 8层第 1塔)




问题1,10版的程序中,框架结构中,程序貌似默认用地震剪力与地震层间位移比计算层刚度比,但是为啥还给出了剪切刚度的比值?到底这个Ratx还要不要参考?或者说Ratx1的结果才为正解?

只看楼主 我来说两句

    llmmff3636451 沙发
    别的大神说的 Ratx1 最好大于1 如果不大于一Ratx 一定要小于2 就是根据这个来的
    Ratx,Raty : X,Y 方向本层塔侧移刚度与下一层相应塔侧移刚度的比值
    Ratx1,Raty1 : X,Y 方向本层塔侧移刚度与上一层相应塔侧移刚度70%的比值
    或上三层平均侧移刚度80%的比值中之较小者

今天摊上大事了,野蛮打孔啊,怎么补救

说起来就晦气,高高兴兴装修过程中,谁知野蛮装修,乱打孔,睡觉都不踏实了。先说房屋描述: 房屋情况,三层的框架结构小楼,第三层为像伞的屋顶。 房屋各楼层示意图: 一层情况: 1 楼情况(好像不太严重): 柱子位置:房屋中间,该柱子一直延伸到3 楼楼顶,象伞的骨架。 柱子(?X ?大概400*400)上开了两个标准的的暗盒的位置高度 后果:表面两根靠在一起纵向中间的螺纹钢被割断了(该处往上好像没看到类似的钢筋了,横向的匝筋断了五六根
