摘要

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.

7. Mechanical properties of various concrete after high temperature exposure Mechanical property of various types of concrete after high temperature exposure is investigated. Considering compressive strength requirement for a vertical element in high rise building, concrete specimens with various design strengths of 35, 80, 100, and 150 MPa were tested. Particularly, the influence of incorporated steel fiber on fire resistance is of interest in this study. Experimental results show that the fire resistance depends on the design strength and steel fiber content. Normal strength concrete (NSC) of a design strength of 35 MPa or high performance concrete (HPC) of 80-100 MPa does not spall when exposed to 100-400 °C of temperature. However, an explosive spalling occurs at 300 °C when the HPCs contain 1 vol. of steel fiber. Ultra-high performance concrete (UHPC) of a design strength of 150 MPa and 1.5 vol. of steel fiber also shows dramatic spalling at 300 °C. The experimental results found in this study can contribute to a better understanding of the behaviors of HPC and UHPC under fire and the role of steel fiber on the fire resistance. [O] . 2017
