刚架拱桥斜撑破坏及加固后可靠性分析
Bracing strut failure and its reliability analysis after reinforce in framed arch bridge
摘要
Abstract
Based on the framed arch bridge mechanical behavior and its component structure defects, a solid model of batter brace by means of ANSYS program was established to simulate the reduction of the strength in the wet formed joint of the batter brace, resulting from the descent of the elastic modulus of the concrete. Based on its reliability analysis after reinforce in the framed arch bridge, the the residual service-life of bridge could be predicted.关键词
