infrastructure have severely damaged property and lives, necessitating in-depth study of the progressive collapse analysis of multi-story buildings subjected to blast loading. Typically, much of the research is centered on Alternate Path Method (APM) with sudden column removal, ignoring the optimal site of the blast loading. A 3D model of a 12-story steel building with a direct simulation of the blast load is suggested in this thesis. Additionally, the effect of blast loading at various places has been investigated.
Building damage from bombs is influenced by the type and design of the structure, the material utilised, the location's explosive device's range, and the charge weight. The case studies, which are drawn from a variety of nations, are by no means exhaustive because there may be many more explosions in the future and more reports of collateral damage to building subsystems.
Vehicle-borne and package-borne blast events have both been taken into consideration. The blast load is analytically determined by the numerical model of the structure, which was developed using the "SAP 2000" software. The published example of a tubular steel beam subjected to blast loads is used to validate the numerical model. On the basis of the results of the final analysis, suggestions have been made to prevent the collapse of steel buildings.

The purpose of this paper is to examine a study of the progressive collapse of a steel frame building with a ten-story seismic design that was attacked by a vehicle-borne explosive device. In this study, the collapse potential of a structure is assessed using a two-step process.
1. INTRODUCTION While it may not be possible to totally prevent terrorist attacks on buildings, there are many ways to greatly reduce the damage that these assaults do to buildings and other facilities. Finding the approaches that are most likely to be successful in limiting the negative impacts of the assaults requires an understanding of the building, its intended use, and any potential hazards brought on by terrorist attacks. When compared to the total lifetime costs of the building, the cost of enhancing it for a "certain level" of resistance against terrorist attacks may not be considerable (including the land value and security monitoring). Several components of terrorism risk management are discussed in this chapter together with related financial and technological legal concerns.
The sophisticated Delayed Rejection Adaptive Markov Chain Monte Carlo Simulation algorithm first assesses the structural damage. With the aid of the program LS-DYNA, a numerical model of a steel building is created in the second step. In second stage, two case studies are selected for numerical model analysis. In the first case study, the basement-level column C6 and B6 are immediately targeted by the explosive explosion.
A bomb explosion inside or around a building can have catastrophic results, causing interior or external building components to be damaged or destroyed. Large framework, walls, doors, and windows are destroyed, and building services are interrupted.
