大型多纵梁斜交渡槽结构受力特性

FINITE ELEMENT ANALYSIS OF LARGESCALE SKEW AQUEDUCT BRIDGE

摘要: 本文采用空间杆系有限元方法,旨在对同跨度斜交渡槽与正交渡槽进行计算对比,使对斜交渡槽受力特性有一个较为清晰的认识,从计算结果对比来看,斜交渡槽的内力较为复杂,是典型的组合受力构件。

Abstract: This paper presents a spatial frame element analysis of large scale skew aqueduct bridge. Comparison is made between skew aqueduct bridges and straight aqueduct bridges. It is found that the internal force distribution of a skew aqueduct bridge is complicated compared with that of a straight aqueduct bridge. A skew aqueduct bridge is characterized by the internal forces of a composite structure.
