Abstract

ABSTRACT:
The current paper investigates the problem of structural progressive collapse.A two-bay small scale reinforced concrete frame has been casted without the intermediate column and dynamically-loaded until failure in order to investigate its behavior and strength under column loss condition. During the test, deflection, cracking, longitudinal strains in both steel bars and concrete, ultimate loads and mode of failure have been monitored. Additionally, an F.E model, using Abaqus 6.13 program is presented.In the numerical model, strain rate effects have been considered. The tested frame was prepared and casted in the reinforced concrete laboratory, faculty of Engineering, Menoufia University while the testing process took place in reinforced concrete laboratory, faculty of Engineering, Tanta University.
