Abstract

In this study, by using ANALYTICAL METHODs, new formulas for calculating natural frequencies of RETAINING WALLs with variable cross section are proposed. Different methods for calculating NATURAL FREQUENCY, such as analytical, numerical and experimental methods, are described. Then, using the exact solution of the problem, new formula for calculating the first mode of vibration in RETAINING WALLs with constant cross sections is proposed. The RAYLEIGH APPROXIMATION method was used to obtain the NATURAL FREQUENCY of RETAINING WALLs with varying cross sections and taking the effect of backfill soil into the consideration. The results obtained from the proposed formulas are compared with the result of numerical analysis using finite element software and good agreements have been found.
