| 摘 要： | 为研究Y型支撑耗能梁段在低周循环荷载作用下的耗能性能，建立了耗能梁段模型。采用非线性壳体有限元，引入混合强化的材料本构关系，对剪切屈服型耗能梁段在循环荷载作用下的滞回性能进行了分析，通过计算，得出影响能量耗散的因素及变化规律。提出设计Y型支撑剪切屈服型耗能梁段的建议和对策。

| Abstract: | In order to study Y type eccentrically braced link beams of behavior under seismic loading,the calculated model of link beam is established,The hysteretic behavior of link beam failed in shear yielding mode is analyzed in details by using FEM with nonlinear shell element.The constitutive laws of steel adopted is mixed with harden model.The failure mechanism and capacity of link beam is achieved under earthquake.The factors and varied rules influencing link beam failed in shear yielding mode is analyzed under cyclic loads.The proposal and countermeasure for designing Y type eccentrically braced link beams is put forward. |
