| 摘 要： | 研究了一种具有自复位能力的钢框架节点的力学性能.该节点在梁柱间通过角钢栓接,并沿梁长布置高强预应力钢绞线.通过对钢绞线施加预应力将梁柱压紧,使节点具备足够的抗弯刚度以满足正常使用情况下的功能性要求,钢绞线同时提供回复力,使节点在地震后具有自复位能力.采用通用有限元分析软件Abaqus 6.9建立节点模型,对9个足尺钢框...

| Abstract: | A new type of beam-to-column connection for steel moment frames is proposed.The new connection uses bolted top and seat angles,and post-tensioned(PT) high-strength steel strands running along the beam.The PT strands tie the beam flanges on the column flange to resist moment and provide self-centering force.A general FEM analysis program called Abaqus 6.9 is adopted to model 9 new connections subjected to cyclic loading.The effects of the prestressing forces,the thickness of the angles,and the distance and t... |
