翼缘开洞H型钢梁的强度研究及其加固措施

摘要

针对实际工程中存在的钢梁翼缘开洞问题展开研究，通过有限元分析的方法系统研究了钢梁翼缘开洞位置处的截面强度，考虑开洞位置、开洞个数对钢梁强度的影响，并给出了实用的补强加固措施，以期指导实践。%This paper launches a study on the flange opening steel beam existing in practical engineering, studies the section strength of flange opening H-shaped steel beam at opening position with finite element analysis method, and considers the impacts of opening location and opening quantity upon the steel beam strength, and shows applicable compacting and reinforcing measures, with a view to guide practice.
