the project is to build a truss that would be able to take a specific amount of downward force remarkably with respect to the weight of the truss itself‚ i.e. to construct a truss that would hold a relatively high efficiency score. And construct the bridge in such a way to as to keep the deflection of the structure at minimal. Introduction First of all‚ what is a truss? In an engineering view‚ a truss is a structure that is made up of series of triangular unit made of straight members that are connected

CHAPTER 1 INTRODUCTION 1.1 Introduction A bridge consists of super structure of steel or reinforced concrete member that is supported on one or more points by cables extending from one or more tower is known as cable stayed bridge. The cable-stayed bridge is one of the most modern bridges. It consists of a continuous strong beam (girder) with one or more pillars or towers (pylons) in the middle Cables stretch diagonally between these pylons and the beam‚ these cables forms intermediate supports

Starting from its size and ending with the structure of the bridge‚ It was considered to be an outstanding bridge at that time. It looked perfect and flawless as it started

Case study 7.2 The Tacoma narrows Suspension Bridge. In the Tacoma narrows bridge project the project planning was fairly planned‚ developers and Engineers did not coordinate proper strategies and a scope management for this project‚ even before its inauguration and opening‚ the bridge exhibited strange characteristics that were noticeable right away. I think the only appropriate project planning was the budget that was obtains by the federal

The very first bridges were made by nature itself‚ as simple as a log fallen across a stream or stones in the river. The first bridges made by humans were probably spans of cut wooden logs or planks and eventually stones‚ using a simple support and crossbeam arrangement. Some early Americans used trees or bamboo poles to cross small caverns or wells to get from one place to another. A common form of lashing sticks‚ logs‚ and branches together involved the use of long reeds or other harvested fibers

the basic design was sound and the suspension bridge had been constructed competently. The project’s original plan and scope management may have been an appropriate one if it was for a shorter bridge. Since this bridge was so long The planners started taking unknown and unnecessary risks when they determined the width of the bridge would be single lane versus double and when they changed the girders from round to flat‚ preventing the wind to pass thru the bridge properly. When the location was chosen

Gate Bridge in San Francisco‚ United States Opened on 27 May 1937 and was the longest suspension bridge span in the world at the time. This remained until Verrazano Narrows Bridge was built in New York in 1964‚ Golden Gate Bridge is now the seventh longest main span in the world. Construction of the 8‚981 feet or 2‚737 m bridge commenced on January 5‚ 1933. The projected cost was $35 million‚ however it was completed at $1.3 million (in 1937) below the projected cost. The Golden Gate Bridge weighs

Basic Research 1. What is a truss and how are trusses used in bridge design? Include the importance of triangular shapes in truss design. A truss is a formation produced by triangular components. The triangular units forming the truss are slim and straight in form. The truss bridges consist of a grouping of triangles. Trusses are used in bridge design to form a series of strong supports using triangles‚ and have the forces of tension and compression acting on them. The importance of triangular

Golden Gate Bridge Lead Designers/Engineers. The First proposal for the Golden Gate Bridge came from James Wilkins‚ who at the time was an engineering student. The cost of James Wilkins Bridge was unrealistic at the time which was 100million dollars‚ but none the less it set the bar for other bridge engineers to try to work out a cheaper solution. During this time a young Joseph Strauss had graduated from the University of Cincinnati with a degree in Business and Economics. Joseph was an avid

The Golden Gate Bridge is a suspension bridge spanning the Golden Gate‚ the opening of the San Francisco bay into the Pacific Ocean. The Golden Gate Bridge was the longest suspension bridge span in the world when it was completed in 1937‚ and has become one of the most internationally recognized symbols of San Francisco‚ California‚ and of the United States‚ San Francisco’s city engineer estimated the cost at $100 million‚ impractical for the time‚ and fielded the question to bridge engineers of whether
