Elasto-Plastic Response of Beams to Dynamic Loads

Abstract

The sfudy was designed to provide and substantiate a simple method for determining the elasto-plastic response of beams subjected to pulse loads. Design charts are presented, and the theory is compared with the results of over sixty beam tests, it was found that deflection can be predicted by the spring-muss approximation with accuracy sufficient for design purposes. Further, It was found that the dynamic reactions were in the range from 1.5 to 2 times the corresponding static values. Experimental resistance curves have been developed from a simple force-equilibrium relation. The Influence of the rise-time of the load is demonstrated. Definite ranges of behavior have been established for step loading.
