Non Linear Dynamic Analysis of G+10 RCC Building Subjected to Ground Blast

In recent decades, use of vehicle bombs and air attacks to destroy nationally important buildings in a city has become a distinct signature of various terrorist organizations around the world. A bomb explosion not only damages the structural frame of the building but also results in collapsing of walls, flying debris, breaking glasses, thus threatening human life. Due to such threats, now a days efforts are made to develop methods for analysis and design of high importance buildings to resist blast loads. This study is about nonlinear analysis and design of typical tall building under blast loading. In this study, the building under consideration is an existing building – Bajaj Brand View building in Wakadewadi Pune. An extensive literature review is carried before carrying out the above analysis so as to understand the methodology of blast analysis and also the codal provisions related to the same. The response in terms of various dynamic parameters and also the performance of the sample building is studied. Response of blast excited building is studied and reviewed for 500kg of TNT placed on ground. The review mainly emphases on nonlinear dynamic response and performance level of building under blast loads. The blast load is calculated IS 4991-1968 criteria for blast resistant design of structures for above ground explosions. The dynamic response of a building is unsystematic and not concentrated at top storey.
