Research On Anti-seismic Property Of Base Isolation Special-shaped Column Frame Structure By Shaking Table Test

With the issuing of national industrial standard Technical Regulations of Concrete Special-shaped Column Structure, ideal living environment is provided to users because the concrete special-shaped column structure organically combines the flexibilities of building beauty and use function with the rational stress property of architectural structure. However, the application of special-shaped column structure is still in the initial stage, the overall anti-seismic property is relatively poor. Considering the structural safety, economy and reasonability, the height of special-shaped column structure is seriously limited in the high intensity area. The combination between base isolation and special-shaped column can enhance the anti-seismic property of special-shaped column, improve the security and solve the problem of height limitation.This paper makes a 1:5 shaking table test scale model of special-shaped column structure. According to the requirements of specification,2 natural waves and 1 artificial wave are adopted as table motivation. Comparative analysis of anti-seismic property between the base isolation special-shaped column structure and non-isolated special-shaped column structure is conducted through the shaking table test. It also researches the dynamic properties of isolated and non-isolated structural systems under different design intensities and seismic waves. Through observing the experimental phenomenon and analyzing the experimental data, this paper discusses whether this system can meet the housing requirements under high intensity and whether it can be used after reducing a unit of intensity, to solve the height limit problem of special-shaped column structure. Facilitate the development of base isolation special-shaped column structure through this shaking table test.Finally, research contents are concluded. Aiming at the above research content, it analyzes and judges the overall anti-seismic property of base isolation special-shaped column structure, points out the deficiency of this research and puts forward relevant suggestion.
