Determining the value of the fundamental period of vibrations of reinforced concrete structures is a complex task. In order to have certain data on the fundamental period of vibration in the earliest design stage, engineers use various approximate methods, which can quickly and simply, but still sufficiently accurate, provide an estimate of the required parameter.The paper presents the most frequently used empirical expressions describing the dependence of the fundamental period in the function of the number of storeys, or the height of the building. All of these expressions, with greater or lesser accuracy, give an estimate of the required value, as shown by a number of examples. A graphic representation of all expressions and their comparison with experimental and numerically derived values has been performed.
