Non-linear dynamic analysis and design concepts for RC beams under implusive loads

Abstract

The behaviour of reinforced concrete (RC) beams under impulsive loading was studied in both the elastic and elasto-plastic regions by use of the finite element analysis. The calculations were then compared with experimental results for verification. Various impact force-time characteristics, beam geometries, material strengths and steel fibre contents were altered to study the effects on items such as behaviour in the critical region, energy absorption at failure and local deformation. These factors were then used to draft out a guideline on design concepts necessary for RC beams under impulsive loads.
