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...
متن کاملHeavy Movable Structure Health Monitoring: Case Study on a Bascule Bridge in Ft. Lauderdale
Heavy movable bridges have different design, operation and maintenance characteristics compared to fixed bridges. This is mainly due to the complex interaction between their structural, mechanical and electrical systems. Movable bridges are viable options in certain terrain conditions and their unique operation provides versatility. At the same time, their intricate interrelation also produces ...
متن کاملNumerical Investigation of Effect of Rock Bolt Angle on Shear Behavior of Rock Bridges
In this work, the effect of rock bolt angle on the shear behavior of Rock Bridges is investigated using the particle flow code in two dimensions (PFC2D) for three different Rock Bridge lengths. Firstly, the calibration of PF2D is performed to reproduce the gypsum sample. Then the numerical models with the dimensions of 100 mm * 100 mm are prepared. The Rock Bridge is created in the middle of th...
متن کاملProceedings of the 57 Annual Conference of the Japan Society of Civil Engineers (25-27 September, 2002) Dynamic Features of End-cross Beam Reinforced Twin-girder Bridge
INTRODUCTION The lower ratio of dead load to live load than existing multi-girder bridges, wide girder spacing and simplified structural system of the twin-girder bridges can give rise to change of dynamic characteristics of the bridges. Wider girder spacing and changing of dynamic features will also effect on a vibration serviceability of the bridges. What is worse, according to running vehicl...
متن کاملComparative Study of PSC Box Girder Multi Cell (3-Cell) Bridge of Different Shapes : A Review Paper
A bridge is a structure providing passage over an obstacle without closing the way beneath. The required passage may be for a road, a railway, pedestrians, a canal or a pipeline. Now a days, bridge deck section of Box shapes are used widely. Most of the bridges constructed are of Box girders. Method of post-tensioning in the construction of bridges is very common today. Most of the bridges are ...
