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
