The Flat Truss Dynamic Characteristics and Seismic Response Analysis

Abstract:

Flat truss is a new form of truss and are widely used in large-span space structure, Suzhou Railway Station roof of the main use of space for large-span steel diamond plate truss structure, the local two-way cross-diamond-shaped truss.Sap2000 v14 large general-purpose finite element analysis software, the modal analysis of the structure, and the modal response spectrum method the structure of X, Y, Z three earthquake, so as to arrive seismic coefficient of internal force distribution law, obtained the natural frequency of the structure, the vibration characteristics of the structure, so that the corresponding structural measures its weak parts of the structure, provides a sufficient basis for the safe use of the design and construction of the structure.
