An investigation of cracks caused by concrete shrinkage and temperature difference in common reinforced concrete bridge structures.
Van-Hau Nguyen
Abstract:Cracking phenomena commonly occur in reinforced concrete structures of bridge and culvert components. While some bridge design standards, such as the AASHTO LRFD standard from America, allow for the presence of cracks, they do not provide direct quantitative limits on permissible crack widths. This research analyzes the crack formation mechanism of reinforced concrete structures under the influence of shrinkage and temperature loading, using the "tension-chord" model from the fib MODEL CODE. The research findi… Show more
