摘要
以三跨连续梁桥支座处牛腿为研究对象,为了研究牛腿的应力分布,建立牛腿细部的MIDAS实体模型,将牛腿随全桥的位移作为强迫位移施加在截面上,对牛腿应力分布特征进行了分析,实例证明该模拟方法是可行的。
Taking the bracket on the support place of continuous bridge with three arches as an example, to research the stress distribution of bracket, it sets up the MIDAS entity model of bracket detail, puts the moving length of bracket with the removal of bridge as forced displacement on cross section, analyzes the stress distribution features of bracket, and practice proves that this simulating method is feasible.
