The structural response and manner of progressive collapse in RC buildings under the blast and Provide approaches to retrofitting columns against blast

In accidents caused by explosion, the initial damage is usually caused by direct hit blast that it causes damage and serious destruction of structural components. In this state, the collapse of structural components and the subsequent progressive collapse may cause an increase in damages and eventua...
