Description
Summary:The need for beam-less space structures has been increasing globally in recent times to meet the demand new construction method is being used popularly known as Flat slab. Flat Slab has many advantages such as ease of application of formwork, more space to occupy, and shorter duration for construction. Implementing efficient load-bearing structures is an often-underestimated measure with enormous saving potential compared to conventional, but rather criteria such as construction costs the possibility of integrating building services components must be socially sustainable including safety, functionality, and adaptability. To construct commercial buildings mostly Flat slabs are economical compared with conventional slabs. The present work involves finding out the equivalent space framework with slab and column elements to reduce the effect of shear. Outcomes of RC Slab-Column joints with Shear Reinforcement from FE (Finite Element) analysis are presented. Three Interior Slab-Column Joints were modelled and analyzed in ANSYS. One slab specimen is without drop and shear reinforcement the second specimen is with drop and without shear reinforcement and the third specimen is without drop and with shear reinforcement. Similarly, three Exterior and three Edge Joints were modelled and analysed. In this study, the enhancement of principal stress, shear stress, principal strain, and shear strain of the slab-column assemblies by provision of shear reinforcement were discussed. The provision of shear reinforcement at slab-column assembly exhibited a maximum shear stress reduction of 42% at the edge joint.
