针对传统防屈曲耗能支撑在应用上的缺点,设计了一种新型防屈曲耗能支撑。该支撑采用型钢组合套管,有自重小、易加工、制作周期短、质量容易保证等优点。对该支撑进行了反复拉压试验研究,试验滞回曲线饱满,相对变形达到1/30时无破坏迹象,表明该支撑具有良好的耗能能力和稳定的工作性能,适合在工程实践中应用。 Aiming at the shortcomings of traditional anti-buckling energy dissipation support, a new anti-buckling energy dissipation support was designed. The support using steel composite casing, a small weight, easy processing, short production cycle, easy to ensure the quality advantages. Repeated tension and compression tests on the support were carried out, and the test hysteresis curve was full. There was no sign of failure when the relative deformation reached 1/30, indicating that the support has good energy dissipation capacity and stable working performance and is suitable for application in engineering practice.
