Abstract

In determining the response of structures under dynamic loads, the response of the free vibration range is considered a special case due to removing the load from the equations. Since the maximum response of structures in the range of free vibration usually occurs under the effect of shock loads such as blast load, knowing what characteristics the blast load and the structure itself must have so that the response of the structure is in the range of free vibration. , is considered an important issue in the analysis of structures against dynamic loads. For this purpose, in this research, reinforced concrete beams were investigated using the equations of motion governing single-degree-of-freedom systems. After solving the equations of motion in the free vibration state and extracting the yield relations, the correctness of these relations was ensured by using valid laboratory research, finite element model and UFC 3-340-02 guidelines. In the following, relations and diagrams were presented to determine the range of responses affected by impulse.
