چکیده
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 influencing analyzed, corresponding measures controlling proposed.

PARAMETRIC STUDY: COST OPTIMIZATION OF NON-PRISMATIC REINFORCED CONCRETE BOX GIRDER BRIDGES WITH DIFFERENT NUMBER OF CELLS
In this paper the parametric study is carried out to investigate the effect of number of cells in optimal cost of the non-prismatic reinforced concrete (RC) box girder bridges. The variables are geometry of cross section, tapered length, concrete strength and reinforcement of the box girders and slabs that are obtained using ECBO metaheuristic algorithm. The design is based on AASHTO standard s...

This paper presents a computational framework for optimal design of non-prismatic reinforced concrete box girder bridges. The variables include the geometry of the cross section, tapered length, concrete strength and reinforcement of box girders and slabs. These are obtained by the enhanced colliding bodies optimization algorithm to optimizing the cost and again CO2 emission. Loading and design...
متن کاملAerodynamic Admittance Research on Wide-body Flat Steel Box Girder
Abstract: Aerodynamic admittance is a key parameter affecting the analysis accuracy of the bridge buffeting response. However, few articles have covered the issue of the wide-body flat box girder with much smaller depth-width ratio (such as 1/12 studied in this paper). Therefore, to explore the real buffeting force of the wide-body flat box girder, experiments of the static force coefficients a...
متن کاملBinary Effect of Fly Ash and Palm Oil Fuel Ash on Heat of Hydration Aerated Concrete
The binary effect of pulverized fuel ash (PFA) and palm oil fuel ash (POFA) on heat of hydration of aerated concrete was studied. Three aerated concrete mixes were prepared, namely, concrete containing 100% ordinary Portland cement (control sample or Type I), binary concrete made from 50% POFA (Type II), and ternary concrete containing 30% POFA and 20% PFA (Type III). It is found that the tempe...
