摘要：

针对目前梁柱刚性连接耐震型节点承载力研究过于片面的问题，提出多高层建筑梁柱刚性连接耐震型节点承载力计算方法。该方法设计筑梁柱刚性连接耐震型节点核心区仅添加钢纤维、仅添加箍筋和同时添加钢纤维与箍筋3种类型，并依据钢纤维体积率和箍筋率不同制作9个试件，以该9个试件为试验对象，设计试验加载方案和测点分布后，利用有限元软件构建多高层建筑梁柱刚性连接耐震型节点试件模型，并利用该模型模拟其试验加载方案，同时通过计算多高层建筑梁柱刚性连接耐震型节点试件的T型钢抗弯承载力、螺栓承载力以及柱翼缘承载力等实现多高层建筑梁柱刚性连接耐震型节点计算。试验结果表明：本文方法计算梁柱刚性连接耐震型节点钢腹板承载力与其实际承载力数值吻合度极高，计算结果较为精准；可有效计算不同核心区添加钢纤维、箍筋等试件的受剪承载力、受弯承载力，同时利用有限元云图可清楚呈现梁柱刚性连接耐震型节点不同承载力分布情况。

Abstract:

In view of the one-sided problem in the current research on the bearing capacity of seismic joints with rigid connections between beams and columns， a calculation method for the bearing capacity of seismic joints with rigid connections between beams and columns in multi story buildings is proposed. This method is used to design three types of seismic joint core area of rigid connection between beam and column： only adding steel fiber， only adding stirrup， and adding steel fiber and stirrup at the same time. Nine specimens are made according to the different volume ratio of steel fiber and stirrup ratio. With the nine specimens as the experimental object， after designing the test loading scheme and the distribution of measuring points， the seismic joint specimen model of rigid connection between beam and column of multi story buildings is constructed using finite element software， The model is used to simulate its test loading scheme. At the same time， the calculation of seismic joints of beam column rigid connection of multi story and high-rise buildings is realized by calculating the bending capacity of T-shaped steel， bolt capacity and column flange capacity of the specimens of seismic joints of beam column rigid connection of multi story and high-rise buildings. The experimental results show that the calculation results of the bearing capacity of the steel webs of the seismic joints of beam column rigid connections by this method agree well with the actual bearing capacity； It can effectively calculate the shear bearing capacity and bending bearing capacity of specimens with steel fibers and stirrups added in different core areas， and at the same time， it can clearly show the distribution of different bearing capacity of seismic joints of beam column rigid connection by using the finite element cloud diagram.

Key words: multi story buildings, building beams and columns, seismic node, bearing capacity, finite element, loading scheme
