 [摘要]為提升高層結(jié)構(gòu)連梁的抗震性能,使連梁盡可能多地耗散地震能量,延長塑性發(fā)展過程,形成抗震防線,基于內(nèi)嵌式鋼板阻尼器復(fù)合連梁,考慮鋼板阻尼器與混凝土的不同粘結(jié)形式,研究了二者的協(xié)同工作機制及破壞模式。針對鋼板阻尼器復(fù)合連梁的鋼板阻尼器與混凝土界面,假定了四種不同的粘結(jié)形式。通過分析得出,粘結(jié)形式的不同導(dǎo)致鋼板阻尼器與連梁的破壞模式存在明顯差異,其中,連梁混凝土的耗能區(qū)域和破壞形式隨著粘結(jié)形式的改變表現(xiàn)為彎剪破壞、彎曲破壞及剪切破壞,而鋼板阻尼器的耗能分布及耗能程度亦均與粘結(jié)形式有關(guān)。最后對鋼板阻尼器復(fù)合連梁的承載能力和耗能能力進行分析,并考慮連梁對墻肢損傷的影響,確定了具有最合理粘結(jié)形式的鋼板阻尼器復(fù)合連梁設(shè)計。

Abstract:In order to enhance the seismic performance of high-rise structure coupling beam, make coupling beam dissipate earthquake energy as much as possible, extend the plastic development process of coupling beam to form seismic lines, the cooperative work mechanism and failure modes of concrete and steel plate dampers were studied by considering  different bond forms between them  based on the composite coupling beam embedded with steel plate damper. Four different bond forms were assumed  considering the surface of composite coupling beams steel plate dampers and concrete. Analyses show that the failure modes have significant differences on steel plate dampers and steel plate damper composite coupling beams because of different bond forms. The energy dissipation regions and failure modes of concrete of steel plate damper composite  coupling beam display bending shear failure, bending failure and shear failure as the change of bond forms, while the distribution and degree of energy dissipation of steel plate dampers also relate to bond forms. Finally, the design of steel plate damper composite   coupling beam with the most reasonable bond form was determined through analyses of carrying capacity, energy dissipation capacity of the damper composite coupling  beam and the  damage impact of the coupling beam on wall limbs.

Keywords:composite coupling beam; steel plate damper; bond form; energy dissipation capacity; failure mode
