| 摘 要： | 根据10个钢筋混凝土框架变梁中节点试件低周反复荷载试验,重点分析了节点核心区尺寸、轴压比等因素对该类非常规节点抗裂性能的影响.结果表明:该类节点左梁、右梁刚度不同,反复荷载下柱端轴压力发生波动,理论分析时可用系数α来表征轴压力对节点区抗裂性能的影响.在以往试验研究的基础上提出包含系数α的框架节点(如常规中节点、边节点、...

| Abstract: | Ten specimens of interior joints with different depth beams were tested under reversed cyclic loadings.The experimental study was conducted by focusing on the influence of joint core dimensions and axial compression ratio on crack resistance of interior joints.Test results indicate that the column axial load fluctuates from time to time because of the unbalanced force occurred in the beam-column subassemblage due to the significant difference on stiffness between the deeper beam and the shallow beam.Based o... |
