Review of Soil Structure Interaction Effects on G+12 RCC Buildings with Corner Shear Walls in Seismic Zone IV

Abstract

Performance-Based Seismic Evaluation (PBSE) has become an essential approach for assessing the earthquake resistance of reinforced concrete (RCC) buildings by focusing on structural performance objectives rather than conventional strength-based design methods. The seismic behaviour of buildings is significantly influenced by lateral load-resisting systems and foundation soil conditions. Among various structural systems, reinforced concrete shear walls are widely recognized for their effectiveness in controlling lateral displacement, inter-storey drift, and structural damage during seismic events [1], [4], [8], [9]. This review paper presents a comprehensive assessment of previous studies related to the seismic performance of RCC buildings with and without corner shear walls under different seismic and soil conditions. A total of eleven research articles published between 2015 and 2026 were critically reviewed, emphasizing structural response parameters such as storey displacement, storey drift, base shear, stiffness, natural time period, and torsional behaviour. The reviewed literature indicates that corner shear walls substantially enhance structural stability and seismic resistance [1], [6], [10], while soil conditions significantly affect earthquake response. Buildings founded on Soil Type III (soft soil) exhibit greater displacement and drift compared to structures resting on Soil Type I (hard soil) and Soil Type II (medium soil) [5], [7], [11]. The review further reveals that limited studies have investigated the combined influence of corner shear walls and Soil Types I, II, and III on G+12 RCC buildings located in Seismic Zone IV using a performance-based framework. Therefore, this study identifies key research gaps and provides recommendations for future seismic assessment and design optimization of medium-rise RCC structures.
