摘要
以某车间栈桥平台的加固为例 ,介绍了改变传力途径的加固方法在工程中的应用。原结构为一平面框架 ,一些构件由于抗弯承载力不足引起了较大裂缝 ,通过添加辅助构件使两个平面框架形成一个三维整体框架 ,改变了原结构的传力途径。使产生裂缝的构件内力值显著降低 ,满足承载力要求。同时验算内力值有所增加的构件 。
Upon strengthening a landing stage, this paper introduced the application of strengthening method by changing force′s transfer road in engineering. The original structure is a plane frame. The cracks appear in some members because bending strength of them is not enough. By jointing two supplementary plane frames into an integrated three dimensional frame, the road of original force′s transfer is changed. The load stresses of the members, in which cracks appear, are increased and meet the demand of safe. At the same time, the members whose load stresses are increased are safe too.
