Abstract

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.

Highlights

  • Reinforced concrete structures have to detailed static and dynamic loading scenarios, as well as industrial or transport accidents or military or terrorist activities due to accidental or deliberate impact or blasting loads (Figure 3)

  • In the study, reinforced concrete problems occurred in neighboring axles, where the element was removed in M8-C and M8-EC prototype buildings

  • In this study indicated that there is no record for comprehensive information about the deterioration of explosion elements in the regulations on buildings to be constructed in earthquake zones in 2007 and 2019, TS 5002000 and TS 498-1997 regulations

Summary

Introduction

Reinforced concrete structures have to detailed static and dynamic loading scenarios, as well as industrial or transport accidents or military or terrorist activities due to accidental or deliberate impact or blasting loads (Figure 3). It is usual for building elements to appear as detailing criteria in case of structural damage by shock as a result of weight drop, vehicle crash on vertical carrier elements or explosion. For this reason, both theoretical and experimental studies have been conducted on the behavior of structural elements subjected to impact loading from past to present. Nowadays, preferred reinforced concrete structures are generally designed considering static, moving and dynamic loads such as earthquake/wind in project stage. Structural analysis generally not include the effects of sudden dynamic impact loads (Figure 1)
