十六层钢筋混凝土剪力墙结构模型模态试验分析

采用相似理论对十六层剪力墙结构进行模型设计，并采用多输入单输出的方法进行传递函数及空间振型分析，得到基固有频率，空间振型，阻尼比及刚度等结构力学参数，为高层建筑结构设计提供了重要的参考依据。

Experimental Modal Analysis of Sixteen-Floor Reinforced-Concrete Shear Wall Structure

The design of an sixteen-floor apartment building which is built with the structure of reinforced-concrete shear wall is made with a plexiglass model based on similar theory.The hammering test has been done on the model with the method of multi-point vibration and single-point output measurement to measure the transfer function.By means of sampling for many times,averaging,technology of curve fitting,and by the principle of model analysis,the first four modal parameters of the model are identified including natural frequency,shape damping ratio,modal mass and modal stiffness,which supply the designers of the tall building with valuable reference data and provide necessary basis for evaluating the anti-seismic property,the safety and thzifty factors of the design of tall buildings.
