【摘要】 结构鲁棒性体现了结构对局部破坏的不敏感性。通过将构件重要性系数和结构剩余影响系数结合起来,计算出结构鲁棒性系数,来定量评估结构的鲁棒性。以20层Benchmark钢框架结构模型为例,对不同楼层框架柱及梁损伤模型进行结构鲁棒性分析,评估不同构件失效时结构鲁棒性的优劣。计算结果表明,移除高楼层位置构件损伤结构剩余影响系数和鲁棒性系数大于移除低楼层位置构件,高楼层位置构件重要性系数小于低楼层位置。更多还原

【Abstract】 Structural robustness reflects the insensitivity of structures to local failure.The robustness coefficient of the structure is quantitatively evaluated by calculating the importance coefficient and structural residual influence factor.The structural robustness analysis of different floor frame columns or beams damage models is carried out to evaluate the robustness of 20 layer Benchmark steel frame structures with different components failure.The computation result implies that the damage structure residual influence factor and the robustness coefficient of the removal of high floor position components are greater than those of the removal of the low floor position components.The component importance coefficient of the high floor position members is less than those of low floor position.更多还原
