The Effect of Cable Material Characteristics on Suspendome

Abstract:

Cable is the key component in the prestressed steel structure. In order to study the effect of cable elastic modulus and expansion coefficient on the prestressed steel structure, Suspendome of Tianbao Center was taken as the research object and APDL language is applied to write a corresponding program, thereby carrying out analysis to the model; The results indicate that the change of cable expansion coefficient and cable elastic modulus have a different effect on the performance of the suspendome: at high temperature, the effect of the expansion coefficient of hoop cable and radial cable is larger on the maximum displacement; at low temperature, the effect of the elastic modulus of hoop cable is larger on the support constrained force. Therefore, it is necessary to give precise linear expansion coefficient and elastic modulus for different cables.
