SOHN, Jung Min  e  KIM, Sang Jin. Numerical Investigation of Structural Response of Corrugated Blast Wall Depending on Blast Load Pulse Shapes. Lat. Am. j. solids struct. [online]. 2017, vol.14, n.9, pp.1710-1722. ISSN 1679-7825.  https://doi.org/10.1590/1679-78254060.

Hydrocarbon explosions are one of most hazardous events for workers on offshore platforms. To protect structures against explosion loads, corrugated blast walls are typically installed. However, the profiles of real explosion loads are quite different depending on the congestion and confinement of Topside structures. As the level of congestion and confinement increases, the explosion load increases by up to 8 bar, and the rising time of the load decreases. This study primarily aims to investigate the structural behavior characteristics of corrugated blast walls under different types of explosion loadings. Four loading shapes were applied in the structural response analysis, which utilized a dynamic nonlinear finite element method.

Palavras-chave : Explosion loads; loading pulse shape; nonlinear finite method; structural characteristics.
