Research on Static and Dynamic Performance of Large-Span Steel Trestle

Abstract:

To study the static and dynamic performance of large-span steel trestle, the steel trestle space finite element model was established with the consideration of the element coupling. The normal stress distribution of trestle bars under the static action was calculated.Combined with subspace iteration method and the time- history analysis, the trestle vibration modal and the dynamic stress extreme value of main bars were analyzed. The structure is more sensitive to transverse earthquake, and under the existing conditions the bar stresses are controlled in allowable range, the structure is safe and reliable.
