Abstract

Designers are drawn to a fresh challenge of improving the capacity of military and civil infrastructures in order to protect lives and properties during blast attacks which is becoming frequent in occurrence throughout the world. However, there seem to remain an ambiguity as to the accurate assessment of threat levels associated with any blast case which may be due to shortage in experimental data of blast loading and its effects on structures as a result of cost. This study therefore evaluates the nonlinear dynamic response of a shear wall structure member subject to blast loading. The extent of damage or response of the wall as per stresses, strains, pressures and displacements were effectively measured with the aid of finite element (FE) which is simulated in ABAQUS software. The laminated wall performed better with an average of over 90% improvement over the control wall in all the response categories considered. Also, while the walls may be damaged, the CFRP laminates contains it in order to save lives.
