考虑轴向约束效应下的RC梁柱子结构试件设计与制作
Design and Fabrication of RC Beam Column Substructure Specimens Considering Axial Restraint Effect
摘要:
RC梁柱框架结构在地震荷载作用下由于受周边构件约束在梁中产生被动轴力导致柱铰机制与节点的剪切破坏。本文根据“强柱弱梁”、“强剪弱弯”、“强节点弱构件”的承载力–延性设计准则，从一榀三层四跨中选型，考虑轴向约束效应对RC梁柱子结构进行设计与制作，为后期进行拟静力加载试验研究结构承载力提供试验研究基础。
Abstract:
Under the action of earthquake, the RC beam-column frame structure causes the shearing mecha-nism of the column hinge mechanism and the joint due to the passive axial force generated by the surrounding members. According to the ductility design criteria of “strong column weak beam”, “strong shear weak bend” and “strong joint weak member”, this paper selects one from three layers and four spans and considers the axial restraint effect on the RC beam substructure, carrying out the design and production, studying the structural bearing capacity for the later quasi-static loading test as the basis of the experimental research.
