AN ANALYTICAL APPROACH AGAINST PROGRESSIVE COLLAPSE AFTER EXPLOSION RC BUILDING

Reinforced concrete structures may be subjected to uncontrolled sudden loads such as weight or rock fall, industrial or transport accidents, military or terrorist activities, controlled or bottled gas, natural gas, fuel tanker or fuel station explosion. It is difficult to predict how the structure will react under dynamic impact loading. However, creating scenarios taking measures against dynamic loading is a simple solution for behavior impact prediction. In this study was investigated to remove of the middle column in the reinforced concrete structure after the internal explosion. Static analyzes were carried out with IdeCAD Static software according to the load distributions after the carrier element removed in the typical building. In this study, load distribution principles are reviewed in accordance with ASCE 7-10, GSA 2016 and ACI 318 recommendations after subtracting elements. As a result, element remove scenarios are required as a design principle for structures.
