Temperature is one of the important reasons causing cracks on bridge structure during construction and operation. In this paper, temperature field produced by hydration heat early thermal stress a 64 m simply supported channel-box girder are simulated casting process, considering time-varying characteristics concrete shrinkage creep, elastic modulus, tensile strength. Then, various parameters i...

Composite box girder bridges may be a competitive solution under certain constraints due to their efficiency and torsional capacity. However, the cross section deflects transversally, creating longitudinal stresses which reduce capacity of section. Those controlled using cross-frames, but detailing those elements become expensive. The procedure described herein provides useful tool for an effic...

Given the increasing age of our built environment, including concrete structures, stakeholders in construction industry require innovative and effective strengthening methods. In several studies onsite applications, iron-based shape memory alloy (Fe-SMA) reinforcements have proven to be competitive alternatives well-established materials. The objective this investigation was study effectiveness...
