SEISMIC RESPONSE OF SOIL DEPOSITS

AN ANALYTICAL PROCEDURE FOR THE EVALUATION OF THE SEISMIC RESPONSE OF HORIZONTAL SOIL LAYERS INCORPORATING EQUIVALENT LINEAR MODULI AND DAMPING RATIOS VARYING WITH DEPTH IS PRESENTED. THE USE OF THIS PROCEDURE IS ILLUSTRATED AND ITS RESULTS COMPARED TO RECORDED VALUES AND TO COMPUTED VALUES USING A CONSTANT DAMPING SOLUTION. THE COMPARISONS INDICATE THAT THE VARIABLE DAMPING SOLUTION OFTEN PROVIDES RESPONSE VALUES THAT ARE IN BETTER AGREEMENT WITH RECORDED VALUES THAN THOSE OBTAINED FROM A CONSTANT DAMPING SOLUTION. THE DIFFERENCE DOES NOT APPEAR TO BE VERY GREAT WHEN THE DEPOSIT CONSISTS OF SOILS THAT ARE ESSENTIALLY OF SIMILAR CHARACTERISTICS. MUCH GREATER DIFFERENCES ARE OBTAINED WHEN THE DEPOSIT CONSISTS OF SUBLAYERS HAVING GREATLY VARYING CHARACTERISTICS. /ASCE/
