A STUDY ON EARTHQUAKE RESISTANT DESIGN METHOD OF AN OPEN TYPE WHARF WITH PNEUMATIC CAISSONS

Abstract

 Seismic characteristic of an open type wharf was assesed both by microtremor measurement and two-dimensional earthquake response analysis. It was shown that natural frequencies of an open type wharf estimated by two methods well agreed. Autohrs next studied a simple erthquake resistant design method of an open type wharf using frame model and one dimensional earthquake response analysis considering the applicability to practical design. A setting method of damping coefficient to be used in the simple design method was proposed.
