Shaking Table Test of Steel Frame Structure in Sine-Swept Vibration and its Virtual Realization

Abstract:

The accurate sine-swept function is proposed by theoretic derivation. The natural frequencies of five-story steel frame structure in transverse direction were identified by modal test. Based on the numerical simulation results of steel frame structure excited by sine-swept vibration, it is proved that the difference of structural response between forward excitation and backward excitation is little,and both the results of them can be used to evaluate the dynamic property of structure. However, it is proper to decide whether the response results of structure should be modified or not based on the dynamic properties of table-board. The conclusions above can provide basis for design and dynamic time-domain analysis of shaking table test in sine-swept excitation.
