辐射式张弦梁结构的地震响应及参数分析

摘要

The radiant beam string structure(RBSS)is a new type of space structure systems. Taking RBSS as our object,and adopting time history analysis to study seismic response,we have got different parameters,such as the rise-span ratio,the sag-span ratio,the prestress of string,and the number of struts. Their influences on seismic responses of the radiant beam string structure are studied.%辐射式张弦梁结构是一种受力性能优良的新型空间结构体系,运用时程分析法对结构进行地震响应分析,并对不同参数如矢跨比、垂跨比、预拉力值、撑杆数进行了分析,得出各参数对辐射式张弦梁结构在地震作用下的影响,其结果为辐射式张弦梁结构的设计、研究和应用提供了一定的参考和借鉴.
