Impulsive loading on reinforced concrete slabs - modelling considerations
Structural modelling has been widely and successfully used for assessing the characteristics and behaviour of materials and structures produced at different scales. There is great economic and practical advantage in using smaller structures exposed to scaled loads that represent the real structure and loads. Additionally, when tests require the use of explosives as in this research, structural modelling provides the powerful tool for avoiding use of greater amounts of explosive, so eliminating unnecessary risks. A structural model is usually described as structural element or assembly of structural elements built to a reduced scale (in comparison with full size structures) which is to be tested, and for which laws of similitude must be employed to interpret test results. This paper describes 'gravity neglected - adequate model' method used to study structural response of RC slabs exposed to close range explosion. Blast parameters were modelled using cube root scaling laws. The results of experiments at two different scales are presented and comparison made between them. Recorded deflections, local and overall damage and crack patterns have been examined.
