摘要
文中结合工程实例,详细介绍了弧形大悬挑钢结构屋盖的设计及分析过程,主要包括结构方案比选和结构设计分析、钢梁扭转效应分析,连接节点设计和加强措施、施工安装措施等.通过分析悬臂梁弯剪扭复合受力状态、校核各项内力效应、复核约束扭转应力,以保证整体结构安全,可为类似工程设计提供参考.
Abstract
Through a practical project,this paper introduces the design and analysis process of a curved large cantilever steel structure roofs,including structural scheme comparison and design analysis,analysis of steel beam torsion effect,connection node design and strengthening measures,construction and installation measures.By analyzing the cantilever beam subjected to combined action of bending-shear-torsion,verifying various internal force effects,and rechecking the constrained torsional stress,to ensure structural safety,which can provide reference for similar engineering design.
