某大型商业综合体结构设计与分析

Structural Design and Analysis of a Large Commercial Complex

某大型商业综合体单体建筑总长约260m,总宽约95m,属于双向超长结构。建筑存在扭转不规则、凹凸不规则。因建筑功能需求,单体内存在大悬挑梁及大跨度梁。本文介绍了结构计算分析过程,针对大悬挑梁及大跨度梁采用型钢混凝土梁柱结构形式进行分析及验算;介绍了型钢混凝土梁柱节点的深化设计与施工要求;分析了双向超长结构的温度应力。结果表明,本项目各项指标均满足规范及设计要求。

A large commercial complex has a single building with a total length of about 260m and a total width of about 95m,belonging to a bidirectional ultra long structure.Buildings have irregular twists and bumps.Due to the functional requirements of the building,there are large cantilever beams and large-span beams in it.This article introduces the process of structural calculation and analysis,analyzes and verifies the use of shaped-steel reinforced concrete beam column structures for large cantilever beams and large-span beams,and introduces the deepening design and construction requirements of shaped-steel reinforced concrete beam column joints.It also analyzes the temperature stress of bidirectional ultra long structures.The results indicate that all indicators of this project meet the specifications and design requirements.
