The protection of buildings, petroleum or nuclear plants, and other infrastructure facilities against blast loads is an important design consideration aimed at increasing the safety and the blast resistance of the structure. Furthermore, in recent times, terrorist activities have resulted in extensive blast damage to civilian facilities and inflicted loss of life, social and economic impact [15]. Consequently, the response of structures and their behaviour under and after explosive load, focusing on enhancing the blast resistance, has been of great interest in the past decade [6]. The behaviour of reinforced concrete (RC) structures subjected to explosive loads has been the topic of extensive research [3,6-8] resulting in proposal of design requirements. Furthermore, the dynamic response of structures has been shown to be affected by its configuration ACI370R-2014. Thiagarajan et al. [6] demonstrated that high strength concrete was very effective in reducing the level of response. Wang et al. [8] also observed that an increase in the explosive charge gradually changes the failure mode of RC slab from overall flexure failure to local punching failure. Various codes of practice [9-16], recommended the principles of explosion and strategies for design methods. The static linear equivalent analysis is one of the most utilized analytical design methods for RC structures against explosive loads that are typically governed by the dynamic load factor (DLF), the dynamic factor is the ratio of the dynamic deflection at any time to the static deflection which would have been caused under the maximum value of the load [9]. In this method, typically multiplying the maximum value of the explosive load by the DLF. The dynamic analysis transforms into an equivalent static analysis which can be carried out using the current codes and standards. However, due to lack of a complete and comprehensive study for computing the DLF, the design is carry out based on approximation by applying the diagrams obtained for beams and considering the ratio of the explosive load run-time to the main period of the member vibration (td/T) [10] (Figure 1).
