【摘要】 JGJ 1—2014《装配式混凝土结构技术规程》中提出框架顶层边节点的其中一种钢筋构造做法是采用柱纵筋向上伸长，梁纵筋锚固在节点区。为验证该节点做法在梁上部纵筋与柱外侧纵筋搭接连接的传力形式、节点核心区混凝土破坏形式或箍筋受力形态，采用ABAQUS软件分析了装配式混凝土框架梁柱节点的受力形态、弯曲变形和破坏形式，为以后研究装配式混凝土框架梁柱节点性能提供了参考。更多还原

【Abstract】 In JGJ 1—2014 ’Technical Specification for Prefabricated Concrete Structures’,one of the top side joints of the frame adopts the method of column upward elongation and beam longitudinal reinforcement anchorage in the joint area. In order to verify the force transmission form of the lap connection between the upper longitudinal reinforcement of the beam and the lateral longitudinal reinforcement of the column, the concrete failure form or the stress form of the stirrup in the core area of the joint, in this paper, ABAQUS is used to carry out the finite element analysis of the beam-column joint of the fabricated concrete frame, and the stress state, bending deformation and failure mode of the beamc-column joint are analyzed, which provides a theoretical basis for the future research on the performance of the beam-column joint of the fabricated concrete frame.更多还原
