摘　　要：目前的抗震设防目标逐渐向震后能够快速恢复功能,甚至部分构件可更换的方向发展。以往试验的研究结果表明,在剪力墙易于破坏的墙角部位安置阻尼器,一方面可保证剪力墙能够具有正常的刚度与耗能能力;另一方面在震后能够轻易方便地更换,且造价低廉。首先运用塑性铰理论对安置区域的尺寸进行了分析总结,然后基于力学计算,对新型摩擦耗能可更换墙角构件进行了理论分析,最后利用一片既有截面尺寸的剪力墙对该新型可更换构件进行了验算。At present,the seismic fortification target is gradually developing towards the direction that the function can be quickly restored even replaced after the earthquake.It can be concluded that installing dampers in the corner of shear wall easy to be destroyed is an effective way to ensure and strengthen its function.Firstly,the size of the resettlement area is analyzed and summarized by using the plastic hinge theory.Then,based on the mechanical calculation,the theoretical analysis and calculation of the friction energy-dissipating replaceable corner member are carried out.Finally,a new type of replaceable member is calculated by using a shear wall with existing cross-section size,which provides a theoretical basis for further experimental and computational research.
