Experimental and numerical evaluation of the compression behaviour of GFRP-wrapped infill materials

چکیده

Glass Fibre Reinforced Polymer (GFRP) composite wrap has become an effective repair system for deteriorated structural columns. It is essential to provide infill material in the gap between retrofitted column and GFRP wrap. So, properties of can significantly influence contribution these wraps thus, affect overall performance structure. However, research on effect confinement materials with various still limited. This study explores effectiveness wrapping its axial compression behaviour concrete, grout epoxy materials. A total 18 unconfined GFRP-wrapped cylindrical columns were cast tested under concentric loading. finite element (FE) modelling was implemented using ABAQUS software analyse The experimental results demonstrated that highly influenced by material. compressive strength modulus elasticity increased due 149 % 77 %, respectively concrete infill, 40 72 whereas negligible efficiency observed wrapped infill. FE analyses showed a good correlation predicting demonstrates valuable insights involving which therefore could be employed better understand systems.
