Anchorage Zone Stresses Model of Interior Diaphragm for Segmental Box Girder Bridge

Polytechnic Journal, 2019
Post-tensioning tendons in segmental box girder bridges are usually anchored in very massive diaphragms. This paper presents an analytical investigation of the anchorage zone stresses for an interior pier diaphragm and a rectangular block model (model of

Compressive behavior of prestressed SFRCFST stub columns after heating: Effect of fresh concrete compression technique

Case Studies in Construction Materials
One innovative and effective technique to enhance the compression response of concrete-filled steel tube (CFST) columns is the compression of the fresh concrete, which actively confines the concrete core by prestressed steel tubes.

Experiments with Externally Prestressed Continuous Composite Girders

Acta Polytechnica, 2001
Steel-concrete composite girders have attractive potentials when applied in bridge construction. The serviceability performance of continuous composite girders is becoming more and more a deterministic parameter in the design of this type of structures ...
