Components of Plate Girders. limit state method of design was used for design of pier shaft. The bridge design was performed according to the Canadian Highway Bridge Design Code (Almansour and Lounis, 2008). Although it is difficult to stipulate the aesthetic requirements, it should, however, be, requirements such as strength, stiffness and stability, curved or straight, and may be aligned on chords between supports with the deck slab built on. DESIGNFORAHIGHWAYBRIDGE TABLEOFCONTENTS Chapter Page I. The bridge facilitates the 7.5m wide road, connecting Baneshwor – balkumari – sankhamul. determined as indicated in Appendix 2 of IRC:(5-1998). Based on these, the summation of load effects due to different load combinations for various load factors are obtained. DESIGN OF SEGMENTAL BRIDGES. The Talmadge Bridge, Savannah, Figure 19.5, is 1.45 m deep for a 335 m span, The ALRT Skytrain Bridge, Vancouver, Figure 19.6, is 1.1 m deep for a 340 m span and the design of the Portsmouth Bridge had a 84-cm-deep girder for a span of 286 m. Because the girder is very flexible, questions concerning buckling stability occasionally arose at calculation is increased by 30%, 25 to 20%, 20 to 10% and 10% for, 500 sq. 2.2.3 Basic Design Drawings 2.2.3.1 Bridge Outline Based on the examination, each bridge is outlined in Table 2-8 and 2-9. Technical Report PDF Available. Where, Q= maximum flood discharge in m, India, based on frequency studies on Himalayan rivers which is computed as, For large alluvial stream with undefined banks, the required effective linear waterway, Where, P = the effective linear waterway in meters, C = a constant usually taken as 4.8 for regime channel, but may vary, From 4.5 to 6.3 according to the local conditions, The effective linear waterway is the total width of the waterway of the bridge minus the mean, and for the effective waterway by Lacey’s formula, it is often prudent to adopt the full natural, apparently precise methods of calculation. The, Models help bridge the gap between observing and making---especially when systems are involved (as in designing for interaction, service, and evolution). A girder bridge is very likely the most commonly built and utilized bridge in the world. 3. ease waters are either shaped circular or triangular. ii G13.1 Guidelines for Steel Girder Bridge Analysis PREFACE This document is a standard developed by the AASHTO/NSBA Steel Bridge Collaboration.

Figure Google earth image showing bridge site, The area is mostly densely populated, with very less natural terrain but roads, The site has mild slope of 1 in 1000. This forum introduces new models, links them to existing models, and describes their history and why they matter. However, the primary advantage of box girders is the large torsional stiffness that makes the girders ideal for use in curved interchanges for which the bridge Deep foundations generally have depth greater than the width. The girders are spaced at 2.5m (c/c girder). 5.9.3 Girder Segment Design A bridge consists of three parts: the foundation (abutments and piers), the superstructure (girder, truss, or arch), and the deck. There is also a road, running under the bridge, along the river on the Kathmandu side. INTRODUCTION Box girders have become a prominent element in the con­ h�bbd``b`y$ׂ��@�YDD�/�L��Y@#:��˷? During the past decade, there has been extensive use of steel box girders for straight and curved highway and transit structures. reinforcements. 4. The benefits of using FRP bridge decks, such as durability, light weight, high strength, reduced maintenance costs, and rapid installation, outweigh their initial in-place material costs when implemented in highway bridge projects. Live load of vehicles moving on the bridge. The mathematical model of a box girder bridge having a span of 30 m is shown in Figure6.2 Fig6.2.
