摘要
本文通过理论分析和工程破坏实例的验证,指明垃圾池承担水平推力存在双重传递路径,楼板作为水平抗侧力体系,刚度较大,将水平荷载传递给垃圾池两端的山墙,是垃圾池的第一道防线;扶壁框架延性好,在楼板发生较大的剪切变形之后,仍能够承受竖向荷载,使结构不至于发生坍塌破坏,同时扶壁框架承担一部分水平荷载,将水平荷载传递给基础和地基,是垃圾池的第二道防线。本文给出了结构设计荷载取值方法和构造措施。
This paper indicates there are dual transfer paths when the waster bunker carries horizontal thrust through the theoretical analysis and verification of engineering failure examples.As a horizontal lateral-force-resisting system,the floor slab has great stiffness,which transfers the horizontal load to the gables at both sides of the water bunker,and it is the first defense line of waster bunker;The structure will not collapse after the floor slab is subjected to large shear deformation,because the excellent ductility of buttress frame which still carries the vertical load.In the meanwhile,the buttress frame carries part of the horizontal load and transfers the horizontal load to the foundation and ground,which is the second defense line of waster bunker.The method of structure design load determination and structural measures are given in this paper.
