Response to Blast Loading of Concrete Wall Panels with Openings
Publication: Journal of Structural Engineering
Volume 125, Issue 12
Abstract
The assessment of reinforced concrete wall panels subject to blast loading may be based upon the formulation of a dynamic, ultimate flexural resistance-deflection function for the element. With the exception of situations in which the explosion occurs at very close proximity to the panel, the ultimate blast resistance is normally based upon the static resistance, which is subsequently modified for dynamic effects. A previous paper by the writers has shown that the static resistance of panels with door and window openings may be determined by the application of a modification factor to the resistance of a similar panel with no openings. In this technical note the method is validated against the results of blast trials using model reinforced concrete wall panels with openings subject to impulsive loading. It is shown that the impulsive blast capacity of wall panels with openings may be determined by applying a factor to the static ultimate resistance.
