Analysis and design of balanced cantilever prestressed box girder bridge considering constructions stages and creep redistribution . Assoc. Prof. Dr. Amorn Pimanmas . Sirindhorn International Institute of Technology . Thammasat University . 1. Introduction . The cantilevering construction method is recommended for medium to long span bridges (span length from 60 to 150 m) The major advantage … After completion the reader should have: a better understanding of the balanced cantilever method of bridge construction and the associated equipment needed, an understanding of the staging and some details of the phases to complete bridge spans, and lastly, the understanding of the method will assist the engineer in cost, schedule, quality
This method is a flexible method of bridge construction where complex and unusual geometrical shapes of dams can be constructed easily. Situations when it is hard to transport pre-fabricated elements either due to size or unreachability, this method is a good choice. Read More: Cast-in-situ Method of Bridge Construction. 2.

Prestressed concrete balanced cantilever bridges are often built using segmental construction. Construction methods. Some steel arch bridges (such as the Navajo Bridge) are built using pure cantilever spans from each side, with neither falsework below nor temporary supporting towers and cables above. These are then joined with a pin, usually after forcing the union point apart, and Civil Works Construction Technology 2 INTRODUCTION Bridge cantilever construction method can be executed both with prefabricated an in-situ concreting. The method does not require false work or centering which leaves traffic under the spans widely unobstructed during construction of the bridge. The only access from the ground is when constructing
