Effect of Cross-Section Shape on RC Specimen’s Behavior Under Asymmetrical Impact Loading

Abstract By applying asymmetrical lateral impact forces on RC specimens, the specimens’ cross-sectional shape is analyzed. The effectiveness of resistance to was examined using a drop hammer. Performing research factors that led failure various specimen shapes and dynamic responses they exhibited. In experiment, eight circular square specimens were used. Includes method failure, force, deflection time history. findings point shear fractures between adjacent support. right side has suffered significant damage, tests all failed. peak force can bear may be greater than ones. Protecting concrete core reducing maximum are benefits specimen. When ratio stirrups raised, there only little variation in specimen’s damage range. This cause slight reduction but it not significant. plateau increased, little. An increase stirrup energy use.
