在对高强轻质混凝土和普通混凝土力学特性对比分析的基础上,以某铁路旅客站房为例,运用SAP2000有限元软件,对C40、LC40两种材料的混凝土框架进行动力特性和地震作用反应谱对比分析。首次进行1:5比例的两层两跨高强轻质混凝土框架模型的缩尺试验,对框架的破坏机制、延性及恢复力特性进行数据收集和分析,其研究结论表明:高强轻质混凝土框架具有良好的滞回特性和耗能能力,可满足地震区抗震性能的要求。
在對高彊輕質混凝土和普通混凝土力學特性對比分析的基礎上,以某鐵路旅客站房為例,運用SAP2000有限元軟件,對C40、LC40兩種材料的混凝土框架進行動力特性和地震作用反應譜對比分析。首次進行1:5比例的兩層兩跨高彊輕質混凝土框架模型的縮呎試驗,對框架的破壞機製、延性及恢複力特性進行數據收集和分析,其研究結論錶明:高彊輕質混凝土框架具有良好的滯迴特性和耗能能力,可滿足地震區抗震性能的要求。

Based on the analysis of high strength lightweight concrete and ordinary concrete mechanical properties of one railway station, the dynamic characteristics and response spectrum of concrete frames made of C40 and LC40 are compared and analyzed with SAP2000 finite element software. For the first time , scale test of two-span and two-storey high strength lightweight concrete frame model of 1 : 5 ratio is carried out, and the datum on framework failure mechanism, ductility and characteristics of restoring force are collected and analyzed. The research results show that the high strength lightweight concrete frame has good hysteretic properties and energy dissipation capacity, which meet the seismic requirements for seismic zone.
