Experimental research on RC square columns wrapped with high performance GFRP under axial compressive load;

Based on the parametric simulation of three RC columns strengthened with CFRP sheets, the applicability and availability of crack models, constitutive relationships on cracks and concrete compressive models are investigated.

In this paper characteristics of near source earthquakes are introduced and its influences on ductility of RC columns are investigated.

In this paper, the studies and applications about the external steel strengthening used in the seismic strengthening for RC rectangular columns are reviewed.

Nine half-scale RC short column specimens based on substandard shear design and details with and without seismic retrofitting have been tested under cyclic loading to investigate the effectiveness of externally prestressing in transverses direction of rectangular columns as a seismic retrofit methodology.
