- Torsional irregularity is a critical factor affecting displacement. In L-shaped buildings, the presence of re-entrant corners further intensifies this behavior by creating zones of stress concentration and increased deformation demand, particularly at the inner corners of the structure. The presence of re-entrant corners in such buildings leads to non-uniform distribution of mass and stiffness, resulting in significant torsional effects during earthquake excitation. This study examines the influence of torsional irregularity on the earthquake response of an L-shaped RCC (G+11) building by considering different levels of eccentricity. The structural models are developed and analyzed using ETABS, and earthquake analysis is carried out using the response spectrum method in accordance with the provisions of IS 1893 (Part 1): 2016. Multiple models are created with varying eccentricity ratios to simulate different degrees of torsional irregularity. Key response parameters such as storey displacement, drift, base shear, and torsional asymmetric ratio are evaluated to understand the behavior of the structure under seismic loading. The results indicate that an increase in torsional irregularity leads to a substantial rise in displacement and drift, particularly at the corner regions of the building. The investigation highlights the importance of considering torsional effects in the design of irregular structures to ensure safety and improved dynamic performance. According to IS 1893 (Part 1): 2016, torsional asymmetry is identified when the ratio of maximum storey displacement to the average storey displacement exceeds the specified limit. This criterion highlights the importance of evaluating displacement variations within the structure to ensure stability and safety. As the degree of eccentricity increases, the torsional response becomes more pronounced, substantially affecting key ground-motion response parameters such as storey displacement, storey drift, and internal force distribution. In this context, the present analysis focuses on evaluating the seismic response of an L-shaped reinforced cement concrete (RCC) G+11 building with varying levels of torsional irregularity. The structural models are developed and analyzed using ETABS, and ground-motion analysis is performed using the response spectrum method in accordance with the provisions of IS 1893 (Part 1): 2016. The work aims to understand the influence of torsional discontinuity on the overall structural performance and to provide insights for improved seismic design of irregular buildings.
