一、概述厂房是由排架、屋盖系统、外墙等组成的一个空间结构。过去在设计中按平面排架进行内力分析与实际情况是不符合的。排架在吊车水平荷载和偏心轮压作用下是和整体厂房共同起作用的。排架将荷载分别传至基础和屋盖;屋盖又将荷载沿纵向传给其他排 I. Overview The plant is a spatial structure composed of a truss, a roof system, and an exterior wall. In the past, the analysis of internal forces by plane racks in the design was inconsistent with the actual situation. The truss works together with the whole building under the crane horizontal load and eccentric pressure. The girders transmit the load to the foundation and the roof respectively; the roof passes the load longitudinally to other rows.
