浅谈抗震设计中影响框架柱延性的因素

Study on Factors of Impacting Ductility of Framework Column in Seismic Design

要提高框架结构的抗震性能,必须保证结构构件具有足够的延性,从而保证框架结构具有更好的变形能力,以吸收较多的地震能量。因此,抗震设计时,将框架柱设计成延性构件尤为重要。影响框架柱延性的因素有很多,笔者对其进行了分析阐述,以便在设计工作中,有针对性地采取一些措施来改善框架柱的受力性能,确保框架柱有足够的延性,从而提高柱的抗震性能。

If you want to improve aseismic behavior of frame structure, make structural members have optimum deformability and release more seismic energy, you must guarautee the structural members with sufficient ductility. Thereof, during aseismic design, the more important is to design the framework column into ductile one. Since the factors to affect the ductility of framework are so many, the author made analysis and adopted some measures upon the problem in order to upgrade under- stress performance of the framework columns and ensure them having enough ductility and higher aseismicity.
