Review on Applicability of Box Girder for Balanced Cantilever Bridge Sneha Redkar1, Prof
International Research Journal of Engineering and Technology (IRJET) e-ISSN: 2395 -0056 Volume: 03 Issue: 05 | May-2016 www.irjet.net p-ISSN: 2395-0072 Review on applicability of Box Girder for Balanced Cantilever Bridge Sneha Redkar1, Prof. P. J. Salunke2 1Student, Dept. of Civil Engineering, MGMCET, Maharashtra, India 2Head, Assistant Professor, Dept. of Civil Engineering, MGMCET, Maharashtra, India ---------------------------------------------------------------------***--------------------------------------------------------------------- Abstract - This paper gives a brief introduction to the 1874. Use of steel led to the development of cantilever cantilever bridges and its evolution. Further in cantilever bridges. The world’s longest span cantilever bridge was built bridges it focuses on system and construction of balanced in 1917 at Quebec over St. Lawrence River with main span of cantilever bridges. The superstructure forms the dynamic 549 m. India can boast of one such long bridge, the Howrah element as a load carrying capacity. As box girders are widely bridge, over river Hooghly with main span of 457 m which is used in forming the superstructure of balanced cantilever fourth largest of its kind. bridges, its advantages are discussed and a detailed review is carried out. Concrete cantilever construction was first introduced in Europe in early 1950’s and it has since been broadly used in design and construction of several bridges. Unlike various Key Words: Bridge, Balanced Cantilever, Superstructure, bridges built in Germany using cast-in-situ method, Box Girder, Pre-stressing cantilever construction in France took a different direction, emphasizing the use of precast segments. The various advantages of precast segments over cast-in-situ are: 1. INTRODUCTION i. Precast segment construction method is a faster method compared to cast-in-situ construction method. -
Design and Construction of Extradosed Bridges in Cold Temperature and Seismic Zones
Design and Construction of Extradosed Bridges in Cold Temperature and Seismic Zones Dr. Matthias Schueller, P.Eng. Vice President Parsons Structures Session 2020 TAC Conference & Exhibition Abstract Extradosed bridges are often described as a cross of a conventional prestressed concrete girder bridge and a traditional cable-stayed bridge because most extradosed bridges built combine a prestressed concrete superstructure with stay-cable technologies. However, this simple definition does not capture the various possible structural systems and different materials that can be found and used for extradosed bridges. Extradosed bridge technology is much more than a prestressed concrete girder with external tendons. The Deh Cho Bridge in the Northwest Territories and the Canal Lachine Bridge in Montréal are two Canadian extradosed bridges featuring steel superstructures with slender composite concrete decks using full-depth precast panels. Although both bridges are very different, they share one important design aspect which governed the design of their superstructures: Both bridges are located in regions with prolonged extreme cold winter periods. Temperatures below 0 °C and cold weather periods lasting up to five months can be a major hindrance when erecting long bridges with conventional concrete superstructures. On the contrary, steel superstructures are light and can be quickly erected, even at cold temperatures without heating and hording given that field welding is avoided. To avoid delays along the critical path in the erection of major superstructures in extreme cold temperature zones, designers should consider erection schemes which make best use of short warm weather periods and reduce negative impacts related to harsh weather conditions as best as possible. -

Systematic Thesis on Network Arches 2013 by Per Tveit, Dr. Ing. Uia, Norway
Systematic Thesis on Network Arches 2013 By Per Tveit, dr. ing. UiA, Norway Co-authors: B. Brunn, M. Chan, W. Graße, F. Millanes, M. Ortega, R. Presland, R. Lee, L. Šašek, F. Schanack, P. Steere, G. Wollmann, T. Zoli. The author prefers network arches with concrete ties and H profiles in the arch. A network arch of this type normally saves around ⅔ of the steel weight needed for other steel bridges. If there are steel beams in the tie, around 1/3 of the steel weight is likely to be saved. Network arches look nice. Network arches have been designed in many different ways. See chapter H: Network arches built or planned. My main publication: “The Network Arch” can be found on my homepage: http://home.uia.no/pert/ under the button “The Network Arch”. It was started in 2000 and is the result of an organic growth. Thus readers will often have a hard time if they are seeking information on specific items. The present publication should be more readable and should lead interested readers more directly to what they are looking for. This publication can only be found on the internet. It will be updated at least till 2014. There are many references in the text. They are supposed to lead to more information on the same subject. Thus the system of references at the bottom of the page is important. Contents Chapter A is a general chapter. The network arch is an arch bridge where some hangers cross each other at least twice. The hangers give the arches efficient support and high buckling strength. -
Polydron-Bridges-Work-Cards.Pdf
Getting Started You will need: A Polydron Bridges Set ❑ This activity introduces you to the parts in the set and explains what each of them does. A variety of traditional Polydron and Frameworks pieces are used in each of the activities. However, they are coloured to produce more realistic effects. For example, the traditional squares are black and used to represent the road on the bridge deck. Plinth ❑ On the right you can see the plinth or bridge base. All of the bridges use one or two of these. They give each bridge a firm base and allow special parts to be connected easily. Notice the two holes in the top on the plinth. These holes are for long struts. These can be seen in place below. ❑ The second picture shows the plinth with two right-angled triangles and a rectangle connected. All three of these parts clip into the plinth. Struts ❑ There are three different lengths of strut in the set. There are 80mm short struts that are used with the pulleys with lugs to carry cables. These are shown on the left. The lugs fit into long struts. On the Drawbridge 110mm short struts are used with ordinary pulleys and a winding handle. ❑ Long struts are also used to support the cable assembly of the Suspension Bridge and the Cable Stay Bridge. This idea can be seen in the picture on the right. ❑ Long struts are also used to connect the two sections of the Drawbridge. ® ©Bob Ansell Special Rectangles ❑ Special rectangles can be used in a variety of ways. -

Department, Sanjay Ghodawat Institutions, Atigre, Shivaji University, Kolhapur, India Abstract: This paper presents study of cable-stayed bridge and extradosed bridge. For analysis 100m, 150m, 200m, 250m and 300m spans are considered. Extradosed bridge is a novel idea bridge between Girder Bridge and cable-stayed bridge. This paper is concluded with study of various parameters of these types of bridges. The parametric study includes response of deck, deck moment, study of pylon, how the response of bridge varies span wise, from aesthetics point of view feasible bridge structure, pylon height and span length to thickness of girder ratio. The parameters of extradosed bridge are compared with cable-stayed bridge. Keywords: CSI Bridge, cable-stayed bridge, extradosed bridge, bending moment, shear force, pylon height, girder depth, aesthetic view. I. INTRODUCTION During XIX century, one of the most relevant contributions to bridge engineering has been the introduction of prestressed technique, which is a solution to the need of controlling stress on elements in bridges. Initially this technique was employed by means of internal and external prestressed tendons, until 1925 when modern cable-stayed bridges appeared –the Tempul Aqueduct, which was developed and built by Eduardo Torroja (Torroja, 1927).
