| 摘 要： | 震害表明,框架结构中的楼梯会发生梯板拉断,梯梁剪断的破坏现象。通过对楼梯抗侧刚度的分析,采用等效刚度的方式,在整体模型中利用斜杆考虑楼梯的抗侧力作用,获得地震作用下梯板及梯梁的附加内力,从而对梯板及梯梁进行当的加强处理,防止楼梯震害的发生。

| Abstract: | It is proved that the stairs and the stair-beam could be destroyed in the frame structure under an earthquake.It is calculated the stiffness of stairs system and is givedn a truss whose stiffness is equivalent to that of the stairs system.The internal forces of the stair and the stair-beam are obtained by integral analysis.As a result,the damage of stair and the staie-beam would be prevented by the proper reinforcement. |
