【摘要】 在高层建筑钢筋混凝土结构抗震设计中,延性是一个重要的概念,提高延性可以增加结构抗震潜力,增强结构抗倒塌能力,并且即经济又合理。延性比是衡量塑性变形能力的指标,延性比的大小决定结构延性的好坏。在结构设计中,我们力求把结构设计成延性较好的梁铰机制,有选择地重点提高结构中的重要构件以及某些构件中关键杆件或关键部位的延性,并重点加强结构构件延性设计。更多还原

【Abstract】 In the seismic design of the Reinforced concrete Structure in High-rise buildings,ductility is an important concept,the improvement of which can increase the potentiality of seismic resistance,strengthen its capability to resist collapse.Meanwhile,it is also economical and reasonable.The Ductility ratio is an indispensable indicator of the plastic deformation capacity,whose range can decide the soundness of the structure’s ductility.When designing the structure,we should endeavor to make it a beam hinge mechanism with a better ductility,focus our attention on the important components or the key rods or parts of the structure selectively and strengthen the ductility design of these parts.更多还原
