Abstract - As a result, high rise structures with basic frame and plate frame systems are the focus of the current work's analytical parametric investigations. In this work, stiff diaphragms are suggested as a possible solution to the issues, and effective analytical modeling techniques are carried out using the super-elements. An effective approach is suggested in the current study to analyses multi-story buildings while taking the impacts of floor slabs into consideration. The current study's aim is to assess the behavior of a structure when the reinforced concrete slab is taken into consideration during structural analysis. Using STAAD Pro software, two separate analyses are performed: Equivalent Static Analysis (ESA) and Response Spectrum Analysis (RSA). The load combinations are taken into account in accordance with IS 1893(Part-1): 2002. For Zone III taken into consideration in this inquiry, the outcomes in terms of design base shear, displacements, responses, and time period in simple frame structures and plate frame structures are compared. It was discovered that taking into account the impact of slabs in the structural analysis of case study buildings will result in reduced displacement values and higher response and base shear values. The outcomes also demonstrate a minor improvement in the lateral stability of bare frames due to the slabs.
