In accordance with the objectives of the research titled "Determination of Usage of Opening Area Effect of Single and Dual Core Type Wall in Multistoried Building Under Seismic Loading," Response Spectrum Analysis was conducted on several building models. These models consisted of 5 single-core buildings with varying shear wall areas: 100% shear wall area (abbreviated as SC1), 90% shear wall area (abbreviated as SC2), 87.5% shear wall area (abbreviated as SC3), and 83.33% shear wall area (abbreviated as SC4).Furthermore, the Response Spectrum Analysis was extended to include six single-core structures with different shear wall areas: 100% (denoted as DC1), 90% (denoted as DC2), 87.5% (denoted as DC3), 83.33% (denoted as DC4), 75% (denoted as DC5), and 50% (denoted as DC6).The seismic impacts of all structural cases were examined, involving seismic shake in both the longitudinal and transverse directions, as required by clause 6.3.3 of IS 1893-2016, to ensure compliance with the specified conditions.

In order to identify the most efficient case, various loads and load combinations were applied to all buildings, and the resulting outcome parameters were compared. The study presents the results in both graphical and tabular formats. The analysis findings, generated using the Staad Pro software, are presented in tabular form alongside multiple graphs with different parameter values.It is important to acknowledge that these research findings provide valuable insights into the effects of opening area in single and dual-core type walls in multistoried buildings under seismic loading. However, further research and validation are required to establish the practical implications of these findings in real-world construction scenarios.
