| 摘 要： | 为研究新型结构体系-钢交错桁架结构在地震作用下的动力特性,首先提出一种新的计算模型--伪空间模型,在通过模态分析和Pushover分析验证了由伪空间模型研究钢交错桁架结构横向抗震性能的可行性之后,对10层、15层和20层钢交错桁架结构分别进行IDA分析,并通过分析结构的动力响应,评估其抗震性能,研究成果对分析钢交错桁架结构的动力特性具有一定意义.

| Abstract: | A new computing model(pseudo-space model)is proposed to study on the dynamic characteristics of a aew structure system(steel staggered truss structure)under the earthquake.The pseudo-space model is verified for researching the horizontal seismic performance of steel staggered truss structure through modal analysis and pushover analysis,and IDA analysis is performed for 10-,15-and 20-storey steel staggered truss structure respectively.The seismic performance of steel staggered truss structures is assessed by analyzing the structural dynamic response,and it shows that the research results are important for the analysis of steel staggered truss structural dynamic properties. |
