Key words: high-rise frame; unequal strength of concrete beams and columns; construction methods 中图分类号:U227.4 文献标识码:A 文章编号: 1 引言 高层建筑框架梁柱节点出于满足抗震柱的轴压比[1]限制和节约造价的考虑,梁柱混凝土强度采纳不等的强度等级,常见的是柱的混凝土强度高于梁的混凝土强度,施工时选择什么方法浇筑混凝土来确保梁柱节点抗震和承载力要求,是长期困扰着施工技术人员的一个难点问题。节点施工时归属于柱,能否采纳强度较低的梁混凝土等级来实施一时难以把握。因为一旦施工方案选择不当,便会造成极大的节点抗震能力和承载力不足的安全隐患,违反抗震设计的原则和目标要求。因此,基于框架柱混凝土强度等级比同一层梁高的实际情况,本文重点分析了高层建筑框架节点设计和施工的现实问题,通过对此类问题的理论与实践思考,提出了两个满足框架节点设计和施工质量的建议,该建议有益于梁柱节点混...
