钢-混组合桥墩轴压行为分析

Analysis on Axle Load Behavior of Steel-Concrete Combination Bridge Pier

钢-混组合柱子是钢-混凝土组合结构的形式之一,该结构具有良好的抗压、抗震和抗弯性能,在工业工程中有较广泛的应用,如应用在受压为主的拱桥的拱肋和受压为主的柱子,但是在桥梁桥墩中的应用进展缓慢,根据钢-混组合桥墩优越的性能特点,结合桥梁桥墩的结构受力实际情况,对钢-混组合桥墩的轴压行为进行模拟分析,分析结果为钢-混组合桥墩的设计及施工提供参考借鉴。

Steel - concrete combination column is one of steel - concrete combination structure type, which has good compression resistance, anti - seismic and bending resistance. It is widely used in industrial engineering. For example, it is used in arch rib of arch bridge relying on compression and column relying on compression. But it is seldom used in bridge pier. According to the good performance features of steel - concrete combination bridge, and in combination with the practical situation of structural stress of bridge pier, the simulation analysis on axle load behavior of steel - concrete combination bridge pier is made, thus providing reference for the design and construction of steel - concrete combination bridge pier through analysis resuh.
