首先简述建筑结构塑性铰的定义及性质;其次将塑性铰与理论铰作理论对比分析,并利用SAP2000引入一例单跨简支梁,分别在简支梁的跨中截面定义塑性铰和理论铰进行有限元分析,证明理论对比分析的结果;最后利用SAP2000对一栋10层建筑结构进行静力弹塑性Pushover抗震分析,得到其塑性铰的发展图,找出结构容易出现塑性铰的抗震薄弱部位,提出结构设计措施、局限性和对未来的展望。
首先簡述建築結構塑性鉸的定義及性質;其次將塑性鉸與理論鉸作理論對比分析,併利用SAP2000引入一例單跨簡支樑,分彆在簡支樑的跨中截麵定義塑性鉸和理論鉸進行有限元分析,證明理論對比分析的結果;最後利用SAP2000對一棟10層建築結構進行靜力彈塑性Pushover抗震分析,得到其塑性鉸的髮展圖,找齣結構容易齣現塑性鉸的抗震薄弱部位,提齣結構設計措施、跼限性和對未來的展望。

The article briefly describes the definition and nature of the plastic hinge in the building structure;Secondly, the author compare plastic hinge with theory hinge,and analyze their nature,but also give an example of Single span supported beam,we finite element analysis the simply supported beam when the plastic hinge and theory hinge separately appear in the midspan section,resultly it could prove the theory of comparative analysis.Finally,we realize a static force elastic-plastic pushover analysis to a 10-layer frame structure with SAP2000 program,resultly the plastic hinge develop-ment figure is arising,so the weak region can be found out,we should suggest the way in the structural design,also the limitations, future prospects and ending are proposed.
