冷库为专业性较强的建筑,其结构与普通建筑略有不同,通常因净高的要求采用板柱-剪力墙结构类型,砌体外围护墙一般采用自承重墙,不同于普通建筑的框架填充墙形式,自承重墙自成结构体系,墙体荷载直接传递给基础、地基梁或地下室外墙。自承重墙与主体结构之间于楼层标高处采用锚系梁杆进行柔性连接,将其墙身法线方向的风荷载和地震作用传递至主体结构承担。本文应用实例进行分析当冷库建筑采用自承重外墙时,自承重外墙与锚系杆的内力分析与设计,同时考虑锚系杆连接的自承重外墙对主体结构的影响。
Cold storage is a highly specialized building whose structure is slightly different from that of ordinary buildings. Generally, column-shear wall structure type is adopted due to the requirement of net height. Self-supporting walls of masonry external retaining walls are generally used, unlike normal buildings The frame fills the wall form, self-supporting wall self-contained structural system, wall load directly to the foundation, foundation beam or basement wall. The self-bearing wall and the main structure are flexibly connected by the anchor beam at elevation of the floor, and the wind load and earthquake action in the normal direction of the wall body are transmitted to the main structure. In this paper, an example is used to analyze the internal force analysis and design of self-supporting external walls and anchor bars when the cold-stored buildings adopt self-supporting external walls. The influence of self-supporting external walls connected by anchor bars on the main structure is also considered.
