سلوك هيكل إنشائي خرساني عرضة للانفجار على الأرض

Abstract EN

In the present scenario, terrorist activities are increasing day by day and they mainly target structures and crowded places.

The buildings are generally not designed to resists the explosive loads and these loads causes disastrous damage to structural members or results in collapse of buildings.

Thus, it is essential to understand the performance of structures under explosive load to know which element needs to strengthened.

In the present work, a RCC building of G+5storey subjected to RDX (Research Department eXplosive) (cyclonite) explosive of 150kg is considered for the study.

The positive phase parameters of explosive load of various standoff distances are determined as per UFC 3-340-02[5] and per India code IS:4991-1968[6]..

The linear static analysis is performed using ETABS 2016software.

Has been determined :1.

Story drift, 2.

Column and beam forces 3.

Displacement of the building.

It was observed from the results of this study that by maintaining the explosive charge and changing the standoff from the source, structure is safe at a distance of 70m.
