| 摘 要： | 为研究变电构架高架柱与人字柱连接节点的受力性能和破坏机理及高强钢材在变电构架中的适用性,进行了2个1/2模型试件的试验研究.其中试件SP1的钢管柱为Q345钢,加劲肋为Q235钢,试件SP2的柱和加劲肋均采用Q420钢.试验时先施加用于模拟构架梁反力的竖向荷载并保持不变,然后施加模拟导线拉力的水平荷载,单调加载直至破坏.根据试验结果,得到了试件的承载力、破坏模式、受力机理和应变分布及变化规律,给出了设计建议,供工程设计参考.

| Abstract: | In order to study the mechanic behavior and failure mechanism of connection between A-column and elevated column in substation frame and to study the application of high strength steel material,two half scale models were tested under monotonic transverse loading to simulate the tensile force of power line,while vertical loads kept constant to simulate reactions of beam truss.The specimen SP1 were made of Q345 for columns and Q235 for stiffeners,while SP2 were Q420 for all the members and plates.Based on the... |
