On the Assessment of the Dynamic Response of Soils

Abstract

The paper discusses two approaches for determining the dynamic response spectra of structures in which the effect of site conditions are taken into consideration. From the response spectra the estimation of maximum base shear is indicated. In light of the presented discussion, the earthquake loading as stipulaled in the Ethiopian code of practice was examined. It has been found out that the loading criteria given in the code for structures founded on soft soils need modification and in consequence thereof a recommendation is proposed.
