Effects of Belt Truss Integration on Flat Slab Systems with Drops Under Seismic Loading Conditions

Recent urban development trends have led to increased use of flat slabs for their aesthetic appeal and construction ease. However, their behaviour under seismic conditions remains a topic of study. The response of this system to lateral forces is influenced by various factors, including the building’s height, the dimensions of the floor plate, the positioning of the shear wall core, and the spans of the flat slab, among others. The study analysed G+10-storeyed buildings with a belt truss system using ETABS 20. Dynamic analysis was conducted based on earthquake data sourced from IS 1893:2016. This research investigates the seismic performance of flat slabs with drop panels, considering shear walls at the core and the influence of the belt truss system. Preliminary findings show that drop panels enhance load-bearing capacity, while shear walls reduce time period, and lateral displacements during earthquakes. These results emphasise the importance of belt truss systems in enhancing seismic performance and promoting safety and resilience in earthquake-prone areas.
