SEISMIC BEHAVIOUR OF SHEAR WALL - SLAB JOINT UNDER LATERAL CYCLIC LOADING

The present work aims to study the seismic performance of exterior shear wall - slab joint with non-conventional reinforcement detailing.. Four joint sub assemblages were tested under reverse cyclic loading applied at the end of the slab. The specimens were sorted into two types based on the joint reinforcement detailing. Type 1 model comprises of two joint assemblages having joint detailing as per the conventional detailing of slab bars at the joint. The second set of models (Type 2) comprises of two specimens having additional cross bracing reinforcements for the joints detailed as per the provisions given for beam – column joint in IS 13920:1993. Analytical investigations were employed to compare the experimental results. The experimental results and analytical studies indicate that additional cross bracing reinforcements improves the seismic performance.
