在某培训中心钢结构工程中,采用消能支撑有效解决了设计过程中出现的层间侧移延性比不满足要求的问题。通过在梁与支撑节点设置金属屈服阻尼器,将普通钢支撑改造成消能支撑,并给出了阻尼器安装位置的节点示意图。计算分析结果表明,消能支撑与普通钢支撑相比,可以有效减小结构在地震作用下的位移反应,提高结构的安全储备,具有良好的经济效益。
In the steel structure project of a training center, the energy dissipation support effectively solves the problem that the interlayer lateral ductility than the unsatisfied requirement appears in the design process. By setting the metal yielding damper at the beam and the supporting node, the ordinary steel support is transformed into the energy dissipating support, and the schematic diagram of the node where the damper is installed is given. The calculation and analysis results show that the energy dissipation support can reduce the displacement reaction of the structure under the action of the earthquake effectively and improve the safety reserve of the structure, which has a good economic benefit compared with the ordinary steel support.
