摘要
随着社会主义经济建设的不断深入,以及节能建筑的发展,建筑加固与改造将作为21世纪人类建筑发展的主题。文章依据江苏省如皋市某大型商场实际改造工程中,由植筋技术形成的钢筋混凝土框架结构外节点为原型建立模型,进行数值模拟分析,并在梁柱结合面处增设附加植筋建立另外两种模型进行对比分析后得出:增设附加植筋可以有效的提高梁柱节点的屈服强度以及极限承载能力,改善节点的耗能性能、延性等抗震性能,为实际的建筑改造工程提供了参考价值。
With the unceasing of socialist economic and energy-saving building construction development,the building reinforcement and reconstruction will be the theme of human building development in 21st century.Based on a large mall in Rugao of Jiangsu province by actual renovation project of planting-bar technique of reinforced concrete frame structure form for the prototype model building,the node numerical simulation analysis,and junction plane place set up additional beam-column planting-bar establish two other comparative analysis model show that set up additional planting-bar can effectively improve beam-column joints yield strength and load-bearing capacity,improve the node energy performance,ductility etc,to provide a reference value for the practical building reconstruction project
