Theoretical Study and Experimental Analysis of Variable Curvature Friction Pendulum System Isolation Technology
摘要
Abstract
In order to verify the seismic isolation efficiency of variable curvature friction pendulum system,the mechani-cal performance differences between the equal curvature friction pendulum bearing and the variable curvature friction pendulum bearing were systematically compared and studied through Abaqus finite element analysis.The vibration table test proved that the seismic efficiency of the variable curvature friction pendulum bearing can be improved by about 7%to 23%compared to the equal curvature bearing.Aiming at the problem that the common design software can not simulate the variable curvature friction pendulum bearing,an equivalent sim-ulation method of"bilinear polyline model"is proposed.The feasibility of the equivalent simulation method is verified by detailed analysis and calculation of its hysteretic characteristics.关键词
