Beams And Plates Subjected To Blast Loads

F. Qin, G. Dong & X. Hengbo
Abstract
In this paper, the dynamic shear force in beams and plates in the range of elastic
response is firstly analysed analytically. Then the widely used simplified
analytical method proposed by Biggs [1] for the dynamic shear force is evaluated
and its computational accuracy is presented. Finally, the shear magnification
factor (SMF) of a beam in the range of elastic response is given analytically, and
the effects of the ratio of depth to span and elastic-plastic deformation on the
shear force are analysed by the Timoshenko beam theory and nonlinear finite
element procedure respectively.
Keywords: shear magnification factor, Biggs method, beam, plate, blast load.
1 Introduction
The response of shear force in reinforced concrete (RC) structures subjected to
blast loads is quite complicate and different from
