SIMULATION STUDY ON THE EFFECT OF ECCENTRICITY LOAD ON THE BEHAVIOUR OF PRECAST WALL PANEL IN TERMS OF STRESS DISTRIBUTION AND LATERAL DISPLACEMENT

This research studies on behaviour precast wall loaded with a different eccentricity of load using finite element method. Seven (7) models of the wall were developed and analysed using ABAQUS software. All samples are designed with a dimension of 3000 mm height x 3000 mm length and 150 mm thickness by using the main material, which is reinforced concrete. Steel bar reinforcement for all model precast walls was provided with T10-200 in the vertical section and T10-300 in the horizontal section. The concrete grade used for the design of the precast wall in this study is the C35 with a longitudinal steel support of deformed steel reinforcement bars with a nominal yield strength of 460 MPa and for the mild steel is of 250 MPa. The study shows the decrease in deformation shape curve when the eccentricity value increases up to 10 mm. The study also reveals no significant effect on stress distribution regarding the location of stress under different eccentricities of load.
