摘要
通过对桥进行有限元建模,分析该结构在周围环境气温变化作用下结构的响应,以及采用国内外相关规范对该结构进行温度梯度计算、比较,研究该桥在温度作用下的受力性能。
By establishing the finite element modeling of the bridge, the paper analyzed the response of the structure under the change of surrounding environment temperature, and used domestic and foreign relevant specifications to calculate and compare temperature gradient of the structure, to study the force performance of the bridge under the action of temperature.
