Paper Details

Structural joints are usually sensitive to risky conditions and show failure in such situations prior to anydamage in members connected through them. In Reinforced Concrete Sandwich Panel (RCSP), wall joint behaviour hasnot been studied which plays very important role in overall safety of these structures. Flexural, axial and shearbehaviour of the RCSP has been tested experimentally. While the joint behaviour of RCSP has not been investigated indetail as in Reinforced concrete (RC) frame structures. In typical RC structures the joints are required to be strongerwith heavy reinforcement, which makes the system uneconomical and difficult to construct. In this research, the L-joint ofRCSP wall has been studied under quasi static cyclic loading along with numerical modelling in ABAQUS to have indepth understanding of bending behaviour of such joints. The load- displacement behaviour shows that L-joint in wall ishighly ductile and can resist the maximum moment of 4.4 KN-m with maximum lateral drift of 145 mm for 0.9144 m longwall, also energy dissipation and initial stiffness are calculated based on experimental results. The experimental resultsand numerical model will help the designer to confidently design RCSP wall joints against lateral forces either due toearthquake or wind etc., economically.
