Nonlinear dynamic analysis is a crucial tool for assessing how structures respond to blast loading. In this study, a G+7 building was analyzed using the SAP2000 software. The objective was to understand the behavior of the building and assess its integrity and safety under blast loading. The nonlinear dynamic analysis took into account the interactions between various structural components, such as beams, columns, and slabs, as well as nonlinear material behavior, time-dependent effects, and influences on the environment. The blast loading was applied in the form of a pressure-time curve, mimicking the effect of an explosion. To determine the dynamic reaction of the building owing to blast load, a parametric research is conducted on a multistory G+7 building. Software called SAP2000 has a model of the structure. The outcomes are shown as Time Histories for various Charge weights of 10 kg, 20 kg, and 30 kg as well as various Standoff distances of 10 m, 20 m, 30 m, 40 m, and 50 m. The analysis' findings offer insightful information about the structure's dynamic behavior and performance under blast loading. This information can be used to optimize the design and retrofit strategies for enhancing the blast resistance of similar structures and improving the safety of occupants during such extreme events.
