Confinement of High Strength Concrete Columns with CFRP Sheets

Ultimate strength analysis of composite sections under biaxial bending and axial load. Interaction surfaces of reinforced-concrete sections in

An experimental research has been planned to study the axial compressive behaviour of circular CFST short columns having 150mm*300mm*1mm size filled with different types

Three groups include 15 R.c concrete columns with composite jackets have been tested under axial compression .Test Results showed a significant increase in strength

This paper presents a new model for predicting the compressive strength of steel-confined concrete on circular concrete filled steel tube (CCFST) stub columns

Keywords: Axial Compression, CFRP strips, Lateral confinement strength, Strengthening, Square..

This chapter reviews four different topics; lateral steel confinement models, Circular Concrete Columns Filled Steel Tubes (CFST) and Rectangular Columns
