摘　　要：为解决上海徐家汇中心项目中,梁柱节点域内钢骨变化的定位、劲性钢骨与钢筋的连接、密集钢筋的碰撞避让和加劲板的布设等问题,结合现行的钢筋混凝土劲性结构相关规范、现有的深化原则和三维辅助设计手段,对变截面劲性节点展开深化设计研究。提出了3种深化设计方法来应对这类问题,从而提高深化设计效率,简化施工作业工序,为类似工程提供了借鉴。In order to solve the problems such as the positioning of steel bone changes in the beam column joint area,the connection between stiff steel bone and reinforcement,the collision avoidance of dense reinforcement and the layout of stiffener plate in Shanghai Xujiahui center project,combined with the current relevant specifications of reinforced concrete stiff structure,the existing deepening principles and three-dimensional auxiliary design means,the variable section stiff joint is carried out in-depth design research.Three deepening design methods are proposed to deal with such problems,so as to improve the deepening design efficiency and simplify the construction process,which provides a reference for similar projects.
