摘要
分析讨论了风压狭缝效应、抗震设防设计、连接节点形式3个方面对某工程的高空连廊设计。通过数值风洞的模拟,得到了风压狭缝影响系数;并通过对连廊的抗震概念设计及防震缝宽度取值的分析,对悬挑端刚接节点的受力的有限元分析,认为采用型钢混凝土柱与内伸钢骨组合的节点形式能够满足受力要求,保证梁端内力的有效传递。
Slit effect of wind pressure,seismic fortification design and connection form are analyzed in the design of high-altitude corridor of a project.Slit influence coefficient is derived by the numerical wind tunnel.Through the analysis of seismic conceptual design of connecting corridor and the width of seismic joint,and finite element analysis of the force of the cantilever joints,it is considered that the combination of SRC columns and beam with section steel can meet the stress requirements and transfer of the internal force effectively.
