Investigation of the effect of impact load on steel box elements filled with fiber concrete at different rati̇os

Steel is the most widely used construction material today. In our country until 2000s, the composite construction method was not common nowadays the development process of the composite materials is accompanied with the lighter, more durable and economical modeling of the structural designs. The advantage of steel constructions is that they are less exposed to earthquake-induced forces, they are robust, they have labor and time gains in production and assembly stages, they are applicable in different construction systems, they can be disassembled and reassembled many times and they are long lasting. Steel is recyclable and it is known that the number of times this process is done does not change the characteristics of steel and does not harm the environment. The purpose of this study is to be able to determine the behavior of composite beams in relation to instant loads such as impact. Calculations were done taking into account the fixed and moving loads in the project calculations up to the sun. However, in the case of no sudden impact in our country, there are no specifications in our country and TSE and 2007 Earthquake Regulation do not give information on this issue. This study contains information on the state of impact loading that the structures may encounter. The work done for this reason will be enlightening on national and international platforms. In the study, behaviors against impact force were investigated by using different parameters. The study was conducted on different concrete classes, different proportions of fiber material using weak and strong axial loads on the samples. By using the obtained result, graphs of acceleration-time, velocity-time and position-time are reached with various utilities program. True results have been Achieved by comparing with the obtained data.
