Seismic performance of steel moment frames with variable friction pendulum systems under real ground motions

Öz:

Many researchers have already acknowledged that the base isolation system as the most feasibleand economical method for civil engineering structures exposed to the seismic excitation. TheFriction Pendulum Systems (FPS) have steel concave surface connected with articulated frictionslider and utilized the concept of pendulum for lengthening the period of the superstructure so asto dissipate the seismic energy. The present study investigates on various design approaches forthe evaluation of the seismic response of steel frames equipped with FPS. The response of isolatedframes is simply adjusted by several parameters such as the friction coefficient (μ), the radius ofcurvature (R), the isolation period (T) and the axial load and so 2D, three bay 3 and 7-storey steelmoment resisting frames (SMRF) are designated as isolated frames in order to examine the effectof variation of the R and the friction coefficient on the seismic response of the isolated frames.The R and μ are predefined as 1, 1.55, 2.25 and 0.025, 0.05, 0.1, respectively. The seismic responseof the modelled isolation systems has been evaluated through nonlinear time history analyses, aset of ground motions using SAP2000 software. The local and global deformations are employedto compare the seismic performance of different isolation frames through nonlinear analysis. Theresults showed that the isolated frames having greatest radius of curvature with lowest frictioncoefficient exhibited better seismic performance than other models in terms of the local and globaldeformations.
