A cellular sliding gate is composed of an inner and outer thin plates having plane rectangular geometry and separated by a combination of horizontal and vertical stiffening plane webs. Cellular sliding gates have strength and stiffness besides their lightweight. The main objective of the present research will be concentrated on the study of the structural behavior and responses of the sliding gate under hydrostatic and wave pressures. The simplified structural method of grillage analysis will be tried. The hydrostatic and the wave pressures distributed to the gate are converted into...
