Development of Self-Consolidating Concrete for Bridge Girders and Evaluation of Its Fresh Properties
Self-consolidating concrete (SCC) has been developed for use in precast prestressed concrete bridge girders in the state of Minnesota. Locally available materials were used with a number of cementitious and filler materials, including ASTM Type III cement, Class C fly ash, and blast furnace slag. SCC was successfully proportioned with both natural river gravels and crushed stone as coarse aggre...
متن کاملOptimization of Precast Prestressed Concrete Bridge Girder Systems
60 A practical approach to the optimal design of precast, prestressed concrete highway bridge girder systems is presented. The approach aims at standardizing the optimal design of bridge systems, as opposed to standardizing girder sections. Structural system optimization is shown to be more relevant than conventional girder optimization for an arbitrarily chosen structural system. Bridge system...
متن کاملConstruction of Nagisa Bridge Hybrid System of Cable-stayed Pc Bridge and Steel Suspension Bridge
Nagisa Bridge, a single span footbridge, was recently completed in Aomori prefecture, Japan. The structure of this bridge is a hybrid structure of cable-stayed prestressed concrete bridge and steel suspension bridge. It is the first application as this structure type of bridge in the world. Concrete girders near pylons are supported by stay cables. Steel girders are supported by suspension cabl...
متن کاملPrediction of Deflection for Prestressed Concrete Girders Using a Bayesian Approach
To control the alignment of prestressed concrete bridge during construction, it is reasonable to treat the prediction of the deflection as an uncertainty. This paper presents a Bayesian updating approach to predict the deflection of prestressed concrete girders. A prior distribution is developed by using Monte Carlo stimulation with a proposed deterministic model under a variety of prestressing...
متن کاملApplication of Nanotechnology in Self-Compacting Concrete Design
In this study, first, different mix design of four types of Self-Compacting Concrete (SCC), 1. SCC consisted of only nanosilica, 2. SCC included only microsilica, 3. SCC consisted of both microsilica and nanosilica and 4. SCC without microsilica and nanosilica called as control mix, were casted and tested to find out the values of the Slump Flow, L-Box and 7 and 28 days compressive strength. Th...
