摘要
某商务休闲钢屋盖可分为中央弦支穹顶和钢桁架主骨架.本文介绍了两者的结构体系构成,探讨了各部分对结构承载力的贡献.通过有限元软件sap2000和ANSYS等对整体结构进行了静力、稳定性、连续倒塌和极限承载力等分析,并建立了节点实体模型以验证节点可靠性,结果表明结构能够满足承载力与变形要求,且节点有较大富余度.
The business and leisure center＆#39;s steel roof can be divided into the central dome and steel truss skeleton .The paper introduced the system of the central dome and steel truss skeleton , and each part＆#39;s contribu-tion for the structure bearing capacity .The capacities of the static bearing , stability , progressive collapse were analyzed by finite element software （ SAP2000 and ANSYS ） , as well as limit bearing capacity of the whole struc-ture.The joint physical model was built in the FEM software to verify the reliability .The results show that the structure can meet the requirements of bearing capacity and deformation and that the bearing capacity of joints is enough .
