000010601 520__ $$2eng$$aEquivalent linear one dimensional site response analysis, which approximates the nonlinear soil behavior within the linear analysis framework, is widely used in practice due to its simplicity and ease of use. However, the equivalent linear method has been known to be unreliable in case of propagating strong ground motion or in soft soil columns. Various frequency dependent algorithms have been proposed to improve the accuracy of the approximate solution and better simulate the wide range of shear strains within the duration of the seismic loading. However, the effectiveness of the modified schemes has not yet been fully verified. In this study, the results of the modified equivalent linear analyses are compared to evaluate the degree of improvement and the applicability of the modified algorithms. Results show that there is a significant difference between the developed procedures and they do not always provide improved estimates.
