Numerical Modelling of Structural Behavior of RC Frames With and Without Infill Walls Subjected to Progressive Collapse

This paper aims to develop a numerical model of RC frame considering the same geometrical properties, material properties and boundary conditions in ABAQUS validated with experimental results comparing its force-displacement curve, damage pattern stress strain variations outcomes. The use infill walls increases progressive collapse resistance force, mainly CAA. is due addition compressive action beam bending CAA frame. Plastic hinge was observed at ends case bare However, wall, plastic formed some distance from middle joint interface near adjacent column on first floor second floor. Furthermore, order examine effect full height mechanism, concrete block modeled compare results. It seen that provides much higher force all stages i.e. mechanism stage, transient stage catenary stage.
