In this study, the dynamic behavior of crane beams subjected to moving load is inspected. Moving loads on their system cause significant dynamic effects. This problem called as the moving load problem affects a wide range of applications in engineering. One of the application areas is cranes. By increasing of worldwide production and consumption of goods, so much faster loading and transport is required. This fact has created a need increasing running speed of the cranes. Therefore, in the design of the crane, the dynamic effects arise from the moving loads should be known accurately. Therefore, in this study, the moving load problem is dealt with as part of the crane beams. The objective of study is to detect dynamic effects arise from the moving load and to contribute to the development of numerical approaches for solving this problem in the literature. For this purpose, theoretical and experimental study is performed in two sections. In the first section, the moving load problem in beams is solved by creating a theoretical model as part of the finite element method. In the second section, an experimental setup is created and the dynamic behavior of a crane beam subjected to moving loads is investigated experimentally. Then, comparing the theoretical model and the results obtained from experiments, the effectiveness of the developed theoretical models is discussed. The results of the study indicate that the numerical model developed for crane beams is usable and efficient.
