Effect of Shear Deformation at Segmental Joints on the Short-Term Deflection of Large-Span Cantilever Cast Prestressed Concrete Box Girders
نویسندگان
چکیده
The excessive deflection of large-span cantilever cast prestressed concrete (LCCPC) box girders has always been a complex problem to be solved in bridge engineering. To analyze the effect shear deformation at segmental joints on LCCPC girders, comparison tests were carried out three (PC) I-girders with and PC I-girder without joints, finite element simulation method was proposed based tests. Subsequently, analysis conducted test girder Assistant Shipping Channel Bridge Humen (a continuous rigid frame main span 270 m) using this method. experimental theoretical results showed that compared midspan specimens negligible. Deformation would not significantly increase, even if rigidity reduced or there more specimen. quite small thus insignificant.

Effect of Construction Method on Shear Lag in Prestressed Concrete Box Girders
Most of the previous researches conducted on shear lag of box girders were only concerned about simple types of structures, such as simply supported and cantilever beams. The structural systems concerned in these previous researches were considered as determined and unchangeable. In this paper, a finite element method considering shear lag and creep of concrete was presented to analyze the effe...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Prediction 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...

The monitoring of a precast, prestressed girder bridge during fabrication and service provided the opportunity to observe temperature variations and to evaluate the accuracy of calculated strains and cambers. The use of high curing temperatures during fabrication affects the level of prestress because the strand length is fixed during the heating, the coefficients of thermal expansion of steel ...
