等效间隙元在钢拱架施工中的应用

根据剩余荷载增量的迭代演算法求解受正弦荷载作用的有间隙连接杆件,并用温度力等效间隙对比计算,二者结果一致,再根据桑坝大桥拱架模型,用两种方法对比计算,二者结果也一致,证明了用温度力等效计算间隙元的正确性和实用性。

Application of Equivalent Gap Element in the Construction of Section Steel

Compared with the result obtained from temperature stress equivalent gap contrast calculation,the result of the gapped connecting members which are subjected to sinusoidal load solved by residual load increment iterative algorithm are the same.Using these two methods to conduct contrast calculation,the results are also the same based on the arch model of Sangba Bridge,which proves the correctness and practical applicability of using temperature stress equivalent to calculate gap element.
