Bannosu Viaduct, one of the Honshu Shikoku Bridges, neighboring to the Bisanseto Bridge, is planned to carry 4 lane roadways and 4 railway lines. This viaduct has such high piers as 40 to 70 meters height and its supporting layer is 30 to 70 meters deep from ground surface. This viaduct is therefore essentially liable to oscillate, and the earthquake resistant design is important in structural design. The pier is adopted the type of I section with earthquake resistant wall to secure the rigidity perpendicular to the bridge axis. In this paper, it is feared the shear rigidity of wall is reduced with crack of concrete by drying shrinkage or earthquake. ƒL[ƒ[ƒhi‰pjF R.C. pier with wall, reduction of shear rigidity, experimental study, FEM ‹LŽ–‹æ•ªF - ‹æ•ª @@@@˜_•¶W
