High pier anti-seismic system with hinged straining beams and energy dissipation inclined struts and anti-seismic design method
The invention belongs to the field of engineering design, and particularly relates to a high pier anti-seismic system with hinged straining beams and energy dissipation inclined struts and an anti-seismic design method. According to the method, an anti-seismic system comprising a hinged middle straining beam and multiple layers of buckling restrained braces is arranged, and a novel anti-seismic design method is provided based on the novel shoe structure. In a new aseismic design method, by inputting known design conditions, such as design parameters of bridge double-column high piers, design seismic oscillation, aseismic performance targets and the like, design parameters of buckling restrained braces arranged on different layers can be rapidly determined without complex and time-consuming nonlinear seismic response calculation and parameter analysis, and the design parameters of the buckling restrained braces arranged on different layers can be rapidly determined. And the established anti-seismic performance target is met. According to the anti-seismic system provided by the invention, the defect of the reinforced concrete double-column high-pier type bridge in anti-seismic performance can be overcome, the anti-seismic design process of the pier is greatly simplified by the new design method, the parameter design efficiency of the buckling restrained brace is improved, and the practical engineering application is facilitated.
本发明属于工程设计领域，具体涉及一种带有铰接系梁和耗能斜撑的高墩抗震体系及抗震设计方法。该方法设置包含铰接中间系梁和多层屈曲约束斜的抗震体系，并基于这种鞋新结构提出了新的抗震设计方法。在新的抗震设计方法中，通过输入已知的设计条件，如桥梁双柱高墩的设计参数、设计地震动、抗震性能目标等，无需通过复杂耗时的非线性地震反应计算和参数分析，即可快速地确定设置在不同层的屈曲约束斜撑的设计参数，以满足既定的抗震性能目标。本发明提供的抗震体系可以克服钢筋混凝土双柱高墩形式桥梁在抗震性能上的不足，新的设计方法大大简化了桥墩的抗震设计流程，提高了屈曲约束斜撑参数设计的效率，便于实际工程应用。
