Abstract
Polymer-Matrix Composites (PMC) are a major evolution for energy dissipation when used as infill materials for seismic retrofitting of steel frames; however, they are viscoelastic materials and their mechanical properties are considerably influenced by temperature. The present study intended to investigate the effect of temperature on buckling failure of laminated Fiber-Reinforced Polymer (FRP) sandwich infill panels under in-plane compression. Mode of failure under in-plane compression was studied by means of numerical analysis with ABAQUS platform. Three different types of composite laminates have been employed for skin plates. The effect of fiber-orientation angles on the buckling of PMC infills was studied with four cases of simple stacking sequences. As well as contact length between frames and infill. Results showed that buckling resistance was proportional with contact length and inversely proportional with temperature variation. Furthermore, the laminate stiffness could be modified by orientation of fiber in laminates which could increase the infill panels strength. Among the three materials studied, CFRP showed the most superior properties.
