Abstract
After the attacks of 11th of September 2001 in the United States,
the attention of the world was directed to study the behavior of structures
under extreme loads, which can lead to failure of structures in a very
short time. Recently, numerous experimental and numerical
investigations were conducted in the literature to study the behavior of
different reinforced concrete structural elements such as walls, columns,
slabs, beams and other structural elements under extreme loads.
The review of previous investigations on structures subjected to
extreme loads has shown that 3-D experimental and numerical study that
investigated the behavior of reinforced concrete structures are limited.
Therefore, in the current work, a two-bay small scale reinforced concrete
frame has been casted without the intermediate column and dynamicallyloaded
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.
Although most of the previous experimentally investigated
progressive collapse problems were conducted on 2D structures, the
current work was applied on a 3D structure in order to study the effect of
out of plan elements on the total behavior. Additionally, a 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.
