Abstract
The detrimental effects of blast loads can lead to severe damage in buildings, causing the collapse of structural components. This study focuses on a parametric analysis of blast loads on a Reinforced Concrete (RC) structure in SAP2000 for analysis. The research aims to assess how blast pressure, base reaction, and deformation vary with changes in explosive mass and standoff distances. To determine blast reactions, non-linear time history analysis is conducted through 16 different cases, involving varying distances and explosive masses. The findings reveal that an increase in explosive mass and a decrease in standoff distance result in elevated blast pressure, rendering the structure more susceptible to performance deterioration.
期刊介绍：
The Asian Journal of Civil Engineering (Building and Housing) welcomes articles and research contributions on topics such as:- Structural analysis and design - Earthquake and structural engineering - New building materials and concrete technology - Sustainable building and energy conservation - Housing and planning - Construction management - Optimal design of structuresPlease note that the journal will not accept papers in the area of hydraulic or geotechnical engineering, traffic/transportation or road making engineering, and on materials relevant to non-structural buildings, e.g. materials for road making and asphalt. Although the journal will publish authoritative papers on theoretical and experimental research works and advanced applications, it may also feature, when appropriate: a) tutorial survey type papers reviewing some fields of civil engineering; b) short communications and research notes; c) book reviews and conference announcements.
