Abstract

Objectives: To accurately describe the blast loads on the buildings, the ten storey building is proposed in this study. The primary reaction of the design is analyzed by utilizing the SAP2000 program. Based on IS 4991-1968 code the impact waves are evaluated. To achieve low base shear the proposed method compared with the existing methods like 3, 5, 7 and 9 storey buildings. Methods: The Dynamic exploration is prompted by time history analysis. The tall building structures of RC frame are analyzed with the standoff distances of 30m, 40m, 50m and 60m respectively. The four distinct framework’s sidelong removals, float, and base shear are investigated in this study. Findings: The balanced RC framed constructions are more stable under impact stresses than non-even RC framed structures. The base shear under an earthquake is easily decreased by using the best-sized beams at the top levels of the building. When compared to the conventional techniques, the proposed method achieves low shear base by using the better sized beams. Novelty: The importance of a structure subjected to blast load increased due to accidental events or natural occurrences. It is inevitable that blasting will produce vibration waves, which cause the structural damage. The majority of earlier research has focused on 3, 5, 7 and 9 storey buildings and it not exactly predict the blast load. In order to accurately describe the blast loads on the buildings a more in-depth analysis is required. Therefore this study proposed the 10 storey building, which accurately describe the blast load on buildings and achieves less base shear (3200KN) compared to the existing methods.
