OPTIMAL DESIGN OF NON-PRISMATIC REINFORCED CONCRETE BOX GIRDER BRIDGE: MINIMIZATION OF THE COST AND CO2 EMISSION
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 کاملPost-buckling analysis of non-prismatic columns under general behaviour of loading
The paper shows the effects of behaviour of loading during the buckling process on the value of critical force and initial stability of post-buckling path for elastic, non-prismatic columns. Perturbation method combined with Croll’s manoeuvre makes it possible to derive general formulae for the first or the second correction of the force, and hence to analyze stability in the post-buckling rang...
متن کاملNumerical investigation of the parameters of a prismatic lithium ion battery under load for electrical vehicle
Electric vehicles and hybrid electric vehicles are a suitable alternative for vehicles with hydrocarbons fuels to reduce pollution and fossil resources. The batteries operate as the driving force for these vehicles. One of the most critical parameters of the battery is computing the state of charge (SOC). The best range for SOC of lithium-ion battery is between 20% and 90%, and charging and dis...
متن کاملPARAMETRIC 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...
متن کاملNumerical Investigation of Heat Transfer and Pressure Drop in a Corrugated Channel
The influence of variation in rib-height to channel-height ratio (e/H) on the heat transfer and pressure drop characteristics inside a channel with corrugated upper and lower plates was investigated numerically in the present study. The governing equations were solved by using finite volume approximations for a wide range of (0.06 < e/H < 0.26) and Reynolds numbers (5400 < Re < 23000), with a m...
