ESTIMATING FUNDAMENTAL PERIOD OF SOIL PROFILES

A method for estimating the fundamental period of soil profiles is presented. The profile may have either stepped or continuous variation of soil properties along the depth. Vibration is assumed to be in shear mode. The profile is assumed to be divided into two segments. The stiffness matrix of a segment is obtained by recognising the soil layers in it to be in series and the mass matrix is obtained by assuming the mode shape to be linear within a segment. An eigenvalue problem of small size (2 x 2) results irrespective of the number of layers. A set of numerical examples are solved to demonstrate the accuracy of the method at minimal computational effort. (A)
