Bridges

Bridges Types Assessment There are five main types of bridges, these include the truss bridge, the arch bridge, the suspension, the beam bridge and the cable-stayed bridge. Each of these categories has various strengths, weaknesses and defining features and these are listed and clarified in the following report. The Truss Bridge Truss bridges are a reliable, economical and easy-to-build variety of bridges as they use a combination of tension and compression to provide a high level of…

A beam bridge or known as a girder bridge, is a bridge structure that consists of horizontal beams spanning supported by pillar at each end of the deck. The weight of the beam including the structure itself, plus any load it carries are supported by the downward force into the pillars. The beam bridge works on the principles of compression and tension, where on top of the bridge bends, it undergoes compression and at the bottom it is subjected to a horizontal tension. Therefore, the bridge must…

Analytical Study of the Brooklyn Bridge Throughout the 19th century, there was a considerable amount of public interest in building a bridge that spans connects the City of New York and Brooklyn, which are separated by the East River. This is due to the fact that at the time, the only modes of transportations between the two cities are ferries and boats. The demand for a bridge grew strongest during the winter of 1866-1867, when it was said that “the river was so choked with ice as to render…

November 7th, 1940, the Tacoma Bridge collapsed into the Tacoma Narrows straight in Washington State. The bridge connected the town of Tacoma and the Kitsap Peninsula, and was one of the first major suspension bridges in the western United States. Unlike other suspension bridges constructed around this time, the Tacoma Bridge failed to withstand wind speeds over 40 miles per hour, due to unequal stress on parts of the bridge. The construction of a suspension bridge must include geometric shapes…

Students must also follow directions and understand the prerequisite requirements associated with creating a truss bridge. This lesson plan meets these conditions because it leverages a variety of resources to assemble information about student learning as well as a wide range of appropriate assessment strategies to evaluate student progress. Students are required to…

construction of the bridge Yangmingtan Bridge was a major construction project of the Heilongjiang province. It is the longest river suspension bridge in the north of the Changjiang River in China, so the government gave it great attention. It breaking ground on 2009 December 5th and completed at a marvelous speed and opened to traffic on November 6th, 2011, with an estimated investment of 1.882 billion Yuan (about 300 million dollars) . Considering the traffic around the bridge would increase,…

a. The bridge is in Banff, Alberta within Canada’s first national park (Structure Craft, 2013). It was completed in 2013 by Structure Craft Builders and is one of the longest timber bridges in the world, achieving a span of 80m within its total length of 113m (Structure Craft, 2013). b. Principle Structural System The principle structural system is comprised of drilled piers to support 40m long glulam girders cantilevered (Structure Craft, 2013). The elevation of the bridge displays stepped…

The Ink Bridge by Neil Grant is a compelling novel written in third person about two boys from two different worlds on a journey of silence, Omed was de-tongued by the Taliban for his defiance while Hec experienced a traumatic family event that lead him to silence, fate played its part and the two boys met and were forever connected. We learn just how important it is to build bridges to the world rather than building walls around ourselves, and the significance that friendship and communication…

For the purpose of this project we will be discussing mainly the truss bridge. A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. (john, 2013) A truss is assumed to comprise of members that are connected by means of pin joints, and which is supported at both ends by…

Introduction: The bridge lab project was based on the given scenario in which a reliable bridge needed to be constructed over a river in order to alleviate traffic. The objective was to design a bridge to relieve traffic flow that was also safe, cost effective, and aesthetically pleasing. The constraints for this project included the budget and minimum height and width requirements. The max budget to purchase wood was $200, the minimum height at all points of the bridge was 3 inches, the…
