摘　　要：根据抗震缝设置的结构力学概念,探讨了在梯板端部设置水平抗震缝的抗震措施,包括滑动支座、Z形板及长圆螺栓孔等。通过采用水平抗震缝实现梯板端部水平横向自由滑移,避免斜置梯板形成的抗侧支撑对整体结构抗侧刚度的影响。To avoid staircase inclined slab forming brace members to influence the lateral stiffness of the overall structure,several possible design measures of seismic joints are proposed to release axial stiffness of slab to avoid its bracing effect according to the concept of structural mechanics,including sliding bearing,Z shaping plate and oblong bolt holes.
