Structural design of a large hall project in the west

西部某大型会堂项目集展览、会议、办公、图书馆诸多功能一体,其主楼长320m,宽279m,建筑总高度54m。会堂主楼采用钢结构体系,其结构具有超长、大跨、大悬挑、扭转不规则、楼板不连续、竖向尺寸突变、错层、局部转换等超限项。从本工程建筑主体功能、结构主体组成、结构重要设计条件取值进行了介绍,对大型复杂公共建筑结构设计,具有一定的借鉴意义。

A large hall project in the west integrates many functions such as exhibition,conference,office and library.The main building is 320m long,279m wide and 54m high.The main building of the Hall adopts steel structure system,which has extra-long,large-span,large-suspended,torsion irregularity,floor discontinuity,vertical size mutation,staggered floors,local conversion and other out-of-limit items.This article introduces the main functions of the building,the main composition of the structure,and the values of important design conditions of the structure,which has certain reference significance for the structural design of large and complex public buildings.
