Seismic Analysis of Irregular Multi-storey Building with Bracing and Shear Wall Using Flat Slab
Nowadays, flat slab is taking over conventional slab for multi-storey buildings, and it can be constructed swiftly and more attractive. But it tends to have lower performance in the seismic region. To increase the performance of building in the present work, a multi-storey RC frame building having flat slab is used to evaluate the efficiency of the lateral load resisting element. In the current study considered three irregularities such as mass irregularity, vertical irregularity and plane irregularity. The prominence of the irregularities is analysed for G + 10 storeys constructed in zone IV over medium soil. In order to confine the seismic effect the lateral load resisting elements considered in the study are shear wall and bracings. To identify the optimum location for placing of these elements are considered as corner and middle location. The analysis carried out by equivalent static method using Etabs 2016 software. Total 15 models are studied considering various parameters like lateral displacement, storey drift, storey stiffness, base shear and natural time period, and results are brought out comparing with shear wall and bracings. It is concluded that flat slab structure with the shear wall placing at the corner is found to be very efficient in the present study.
