摘要
针对一座已使用10年的输煤栈桥,运用ANSYS通用有限元软件建立该结构的三维模型;分析了该结构在不同锈蚀等级、不同运载情况下的静力响应;针对结构跨度较大的特点,考虑行波效应,采用多点非一致激励反应谱法进行了结构的地震响应分析,为结构的安全使用提供了参考。
In this paper,at first,a finite element three-dimensional modal is built by ANSYS program for a coal-conveyer-gallery which has been used for 10 years.Then,the static response is got in different case of corrosion level and load weight.At last,based upon the non-uniform excitation response spectrum method[1],the response of seismic excitations is obtained due to the characteristic of long-span.
