密肋壁板结构参数识别与动力复合反演分析
|
摘要
以密肋壁板结构为研究对象,通过试验对密肋壁板结构模态参数识别结果的分析,验证了密肋壁板结构弹性等效模型的可行性;利用试验结果,重构结构动力完备信息,对密肋壁板结构进行动力复合反演分析,从而建立密肋壁板结构弹性层间刚度换算公式。为密肋壁板结构的安全可靠性评价提供了前提和依据。
The vibration characteristics of a multi-ribbed slab structure are researched.The feasibility of the equivalent model of structural elasticity of dense rib panels is verified through discerning the modal parameters of the multi-ribbed slab structure.Besides,summarizing the above results of parameter identification and reconstructing the structural dynamic information,the elastic story stiffness of the multi-ribbed slab structure can be gained by dynamic compound inverse analysis.And then the evaluation of the safety and the reliability of the multi-ribbed slab structure is simply discussed.
