| Abstract: | Some vibration issues of externally prestressed concrete beams under dynamical loads are discussed in the paper. The formula presented by Ayaho Miyamoto is improved and extended. Some formulae for frequency calculation are given when external tendons are arranged in three different configurations. Many factors are considered in the analysis of the beam vibration frequency, and some effective antivibration measures are provided in the end. |
