Parametric study of RCC bridge superstructure under blast loading

Abstract

The paper presents the performance of a Reinforced Concrete bridge under blast loading. IRC has specified probability based design methodology and load factors for designing bridge piers against ship impact and vehicular collision. Currently, no specific IRC design guideline exists for bridges against blast loading. Structural engineering methods to protect infrastructure systems from terrorist attacks are required. Bridges are unique in terms of materials used, length, width, skewness, span, loading, traffic conditions, and overall geometry. This paper investigated the most common types of concrete bridges that is the slab on girder bridge. The analysis and design of structures subjected to blast loads require a detailed understanding of blast phenomena and the dynamic response of various structural elements. Blast load was stimulated as a time history load using STAAD Pro. Software. The reinforced concrete bridge was thoroughly investigated and the results provide insightful information regarding the damage.
