Comparative Analysis of Mid-Rise L-Shape Building Frame WITH or Without Rigid Slab to Determine Cost Effective Unsymmetrical Building Frame

The latest trend in seismic design of structures according to Indian standards implies taking into account the effect of slab stiffness while evaluating designing structure concrete elements – the stiffness affects on size of seismic forces and lateral displacements. In this paper an analysis of effective stiffness of cracked reinforced concrete elements depending on the size of axial force and the amount of longitudinal reinforcement was conducted, taking into account the tension stiffening effect. The results obtained through this analysis were then applied to a residential building of L-shape symmetry. Keywords - l-shape structure, staad, analysis, displacement, cost, slab stiffness.
