混凝土徐变计算模型对预拱度设置的影响对比

On comparison of influence of concrete creep calculation models on layout of camber

通过建立Midas Civil有限元模型,分别采用我国新老规范中对混凝土徐变的不同计算模型计算山店江大桥的预拱度值,得出两种计算模型计算结果的差异,并与实际工程情况相对比,结果表明新规范与实际情况更为吻合,但仍需要做出调整。

According to the estabhshment of the Midas Civil finite element model, the paper adopts the various calculation model of concrete creep of the new and old regulation in China to calculate the camber value of Shandianjiang Bridge, concludes the differences of the calculation results of the two calculation models, compares them with the factual engineering circumstance, and proves by the result that the new regulation is consistent with the factual circumstance, but some adjustment is needed.
