| Abstract | ||
| The aim of this study is to investigate a procedure for the analysis and design of reinforced concrete walls (back and two sides) as part of the structure to resist internal blast pressure. The effect of the blast pressure on the strength, serviceability, ductility, energy absorption capacity of reinforced concrete members (back and two side walls) and their behavior has been studied. This evaluation will specify the required thickness of the two side walls and back walls as part of the structure in addition to the quantity, shape and connection mechanism of steel reinforcement. To achieve the goal of this study, all the variables can be evaluated, experimental program was set up. It was intended to carry out a field test for the structure (box room) which is made of reinforced concrete having the internal dimensions of 3.3m*3.3m*2.6m (10.82 *10.82*8.52) ft. with strip footing having the dimensions 0.53m (1.76 ft). width and 0.54m (1.8 ft). thickness. The structure was subjected to a blast pressure due to a charge of weight 1.5kg (3.31 ib). for a recommended degree of protection in terms of ductility ratio = 2.00 .The objective of the test was justified since no scabbing at all was observed. It was found that the thickness 25cm (0.82 ft). for side walls and back wall can keep all the outside individuals, equipment and buildings safe and away from the danger of fire and fragmentation during the period of blast pressure. Good agreement was found to exit between the theoretical and the experimental results. | ||
