The Nature Frequency of Point-Fixed Glass Facades and the Influencing Factors Study

The resonance phenomenon may occurs when the frequency of the external load which is carried on the structure similar to the structure nature frequency. The structure is unsafe.The displacement and internal forces of structure can reach the maximum. This paper take modal analysis for point-fixed glass facades,get the natural frequencies and modes,calculate various parameters effecting structural frequencies and the variational rules of those frequencies by changing those various parameters.
