摘要
针对实际加固改造工程中常见的既有混凝土梁开洞的情况,采用一般规范计算方法计算并复核既有混凝土梁的抗弯、抗剪承载力,并采用SAP2000软件进行实体单元的有限元分析,提出了提高结构可靠性的节点加固设计方案,可供设计人员参考。
In view of the existing concrete beam with openings,the General Calculation Analysis Method is used for the flexural and shear bearing capacity,and Finite Element Analysis is used for accurate elastic analysis.Based on the analysis results,strengthening measures of joints are put forward to improve the reliability of the structure,which can be used as a reference for designers.
