A Study on Cope Hole Details Considering Fabricaiton

Abstract

Various cope holes are employed in Japanese highway bridges. The shape and size of the cope hole, however, depend on the authority if the hole is applied to the same. In this paper, reasonable shape and size of the cope hole according to a structual details has been discussed in taking account of bridge fabrication process, its efficiency and fatigue strength. Especially, diaphragm details are discussed though stress analysis using finite element method. Finally, how to select cope hole details is proposed.
