The effect of impact force of different heights on steel beam element behavior

Steel and reinforced concrete structures can be exposed to dynamic loads as well as being subject to the effects of static loads. Static loads; loads that change over time or occur suddenly are called dynamic loads. The structural carrier elements can break suddenly when subjected to dynamic loading by another object having an acceleration under static load. Stress changes occur on colliding elements when the objects come into contact with the impact force. Deformations can occur on the elements due to stress changes and these deformations occur in a very short time. Ductility, expressed as the deformation tendency for structural elements, is an important feature for element behavior. The area under the ductility curve is the energy damping capacity that will occur in the element, in other words its toughness. As the dynamic and static loads formed in the elements are different from each other, their deformation capacities and their toughness will be different from each other. Many methods are used to measure the toughness caused by dynamic loads, one of which is a weight reduction method from a certain height. In this study, the behavior of the beam which is one of the structural carrier elements under the impact load is investigated experimentally by weight reduction method. In this study, impact force was applied with the same weight hammer at different heights from steel box profile having the same cross section.
