摘要
某机房是钢筋混凝土框架结构,工程具有错层多,跨度大,荷载重,结构重要性高等特点。介绍变厚度筏板基础的设计,30m大跨度楼盖的设计选型及型钢混凝土梁的设计难点。为提高大震下结构的整体抗震性能,工程采用软钢阻尼器进行耗能,并进行弹塑性动力时程分析。
A calculator room project,which has multi-staggered floor,large span and heavy load,and high structural importance,was reinforced concrete frame structure.The design of variable thickness of the raft foundation,type selection of 30m large-span floor slab and the difficulties of steel reinforced concrete beams were mainly introduced.In order to improve the overall seismic performance of the structure under strong earthquakes,energy consumption by mild steel damper was used,and elastic plastic dynamic time-history analysis was performed.
