楼梯间——地震发生时人员疏散和救援的必经通道。震害表明,多层砌体房屋的楼梯间破坏比较严重。因此,对楼梯间的抗震设计,包括构造措施和施工质量应给予高度重视,以提高楼梯间的抗震能力。1楼梯间所处位置的特殊性楼梯间墙体因缺少各层间楼板的侧向支撑,也因为楼梯踏步的嵌入有可能削弱了楼梯间墙体的整体刚度。除其顶层外的中间层,计算高度较其他部位墙体小,该部位墙 Stairwell - the only passageway to evacuate and rescue people when an earthquake occurs. Earthquake damage shows that the destruction of stairwells in multi-story masonry houses is more serious. Therefore, the seismic design of the stairwell, including the construction measures and construction quality should be given high priority to improve the seismic capacity of the stairwell. 1 The particularity of the location of the stairwell Stairwell wall due to the lack of lateral support of the floor between the floors, but also because of the stepping embedding may have weakened the overall stiffness of the stairwell wall. In addition to its top layer outside the middle layer, calculate the height of the wall smaller than the other parts of the wall
