基于能量系数的损伤控制结构评估及其在钢框架中的应用
|
摘要
根据改进的能量平衡关系,推导了具有较大屈服后刚度系数的损伤控制单自由度体系的能量系数。采用非线性时程分析研究了地震作用下屈服后刚度系数及屈服时序对能量系数的影响。将能量平衡关系推广至多自由度体系,基于能量系数提出了用于判定损伤控制结构的评估方法,并将其用于损伤控制钢框架的评估。结合对损伤控制钢框架的评估分析说明了建议方法的应用,并通过非线性时程分析进行了校验。结果表明,能量系数对结构的屈服时序敏感,建议方法有良好的精度,可用于损伤控制结构的评估和优化设计。
Based on the modified energy balance equation,the energy factor of damage-control single-degree-offreedom systems with significant post-yielding stiffness ratio was derived. The influences of post-yielding stiffness ratio and the yielding sequence on the energy factor were investigated based on a large number of nonlinear dynamic analysis. The energy balance was then extended to multi-degree-of-freedom systems,and a practical approach in dealing with assessment of damage-control behavior was proposed based on energy factors and applied to damage-control steel frames considering yielding sequence. The application of proposal was introduced based on the example structure,and the accuracy was validated by nonlinear dynamic analyses. Results indicate that the energy factor is sensitive to structural yielding sequence. The proposed approach exhibits satisfactory accuracy and can be applied to practical assessment and design of damage-control structures.
