钢筋混凝土十字节点斜撑法加固的数值分析
|
摘要
梁柱节点是钢筋混凝土结构抗震的一个薄弱环节,其失效时往往引起结构的整体破坏。为了减轻因节点脆性破坏而造成的损失,针对梁柱交界处,以钢筋混凝土框架结构中的十字形梁柱节点为模形。对比分析增设斜支撑对节点加固前后的力学性能。结果表明:采用斜撑法加固的节点的承载能力较无斜支撑节点的强。
The structural anti-seismic weak link of the reinforced concrete is the beam-column joints,which will cause structural holistic failure due to joints become invalid.according to beam-column juncture,cruciform beam-column joints of reinforced concrete frame structure are taken as model,the thesis comparatively analyzed the mechanical properties of nodes which are pre and post set inclined brace.The results show that the nodes bearing capacity used inclined brace strengthening is stronger than that unused inclined brace.
