Effect of Different Bracing Systems on the Multi-storey Building Subjected to Blast Loading
Abstract
The recent terrorist attacks and bomb attacks either in India or elsewhere in the world have shifted the attentions of structural designers towards the safety of the occupants and the structures. Especially the terrorist attack on the Twin Towers of America has resulted in an alarming situation and many researchers have focused their attention on the analysis and design of structures subjected to blast loadings. Many softwares available to structural engineers will also enable one to analyze the structure for the blast loading and design accordingly. In this project an attempt is made to analyze a G+6 storied symmetrical building which is subjected to blast loading. A comparative analysis is given when the structure is fitted with X Bracings, Diagonal Bracings, V bracings. For the analysis SAP2000, Version 18 is used along with RC Blast Software. Push over analysis is carried out for all the different cases. The results in the form of Storey Displacement and Storey Drift are compared for all the different cases considered.
Keywords Blast Load, Bracing System, RC Blast, SAP2000, Standoff Distance, Terrorist Attack.
