竖向荷载和不平衡弯矩共同作用下板柱节点的设计

在试验研究和理论分析的基础上，给出了普通板柱节点和配置抗冲切钢筋板柱节点的受冲切承载力计算公式，同时给出了板柱节点在竖向荷载和不平衡弯矩共同作用下等效竖向荷载设计值的计算方法，简化了复杂受力条件下板柱节点的设计．试验研究表明，抗冲切锚栓是有效的抗冲切钢筋类型，不但能提高板柱节点的受冲切承载力，而且能改善板柱节点的延性．抗冲切锚栓的布置方式包括正交布置和径向布置，且抗冲切锚栓应在柱周边区域均匀分布．本文给出了板柱节点抗冲切的设计步骤和方法，并给出抗冲切锚栓的设计方法和构造措施．同时给出了板柱节点配置抗冲切锚栓的算例，验证了抗冲切锚栓的设计方法，可用于板柱节点的工程实践．

Design of slab-column connections under combined vertical force and unbalanced moment

The calculation methods of punching strength of slab-column connections with or without shear reinforcement are given based on test results and theory analysis. The calculation method of slab-column connections under combined vertical force and unbalanced moment is also given, and the design method of slab-column connections under complicated condition can be simplified. Test results show that stud shear reinforcement is one of the most valuable type of punching reinforcements. It can not only improve the punching strength, but also improve the ductility of slab-column connections. Stud shear reinforcement can be arranged in perpendicular and diametrical directions, and it should be evenly arranged around the column region. The design approach and method of slab-column connections is given in the paper, and the design guidelines of stud shear reinforcement are also derived herein. The design example of slab-column connection with stud shear reinforcement is given and the design method of stud shear reinforcement is proved. The recommended design approach can be used in practical structural design as demonstrated in the example.
