Analysis of a cofferdam support and design implications

The procedure used for the analysis and design of a single reinforced concr ete ring beam supporting a large diameter sheet pile cofferdam is presented . A simplified two dimensional model on a powerful commercial structural an alysis program was employed. Non-conventional techniques were used to analy se the ring beam tinder non-uniform loadings of the cofferdam during the va rious stages of construction. Design implications of reinforcing the beam t o cope with these loads is also discussed. (C) 2001 Civil-Comp Ltd. and Els evier Science Ltd. All rights reserved.
