		ABCD's Bridge Design Tips for Kids ^Votes:0 ABCD's Bridge Design Tips for Kids [ Form of Bridge \| Connections \| Properties of Balsa Wood \| Additional Resources \| Further Reading ] So, you've been given a project to design and construct a bridge that will hold the most weight for a given span. Now you are probably wondering where to start. What type of bridge is the strongest? (We get that question frequently from kids.) That question doesn't really have an answer. There are too many variables involved for the question to be meaningful. For example, what are your material constraints? Certainly, it would not be of much use to you were I to tell you that stone arches were the strongest, while you were instructed to build your bridge out of toothpicks. The idea of "constraints" is an important one. The teacher did not tell you that you Read More Go to Site

		Bridges - their structure and function ^Votes:0 Bridges Basic notes about bridges ==== Detailed notes about bridges Other notes about structures ==== All pages about structures Alphabetical index of bridges and other topics Please note that all thumbnails have been replaced by blank rectangles, to reduce bandwidth, because of the heavy usage of these pages. Introduction to the contents of this web-site Although the notes in these pages are about structures, they are not about engineering practice. They simply represent an attempt to understand simple structures. The explanations are not intended as a logical and formal set, like a text book, and they use little mathematics, but every possible effort has been made to make them accurate within their limitations. There is little in these pages about the actual practice of building structur Read More Go to Site

		Geometry of Bridge Construction ^Votes:0 Geometry of Bridge Construction Geometry of Bridge Construction The four kinds of bridges and some combinations A. The beam or truss bridge is, in effect, a pair of girders supporting a deck spanning the gap between two piers. Such a beam has to withstand both compression in its upper parts and tension in its lower parts. Where it passes over supports, other forces come into play. A beam may be a hollow box girder or an open frame or truss. B. An arch bridge can be designed so that no part of it has to withstand tension. Concrete is well suited to arched bridge design. When reinforced concrete is used, a more elegant and sometimes less costly arch can be designed and most concrete arch bridges are reinforced. C. A suspension bridge consists, basically, of a deck suspended from cables slung Read More Go to Site

		Structural Engineering Slide Library: Set B ^Votes:0 Structural Engineering Slide Library Set B: Arch Structures This set of slides covers many of the important aspects of arches as used in the design of buildings and bridges. It includes the following general topics: Masonry arches: historic Masonry arches: 18th and 19th century Three-hinged arches: bridges Three-hinged arches: roof structures Two-hinged arches Tied arches: bridges Tied arches: buildings Fixed arches: historic Fixed arches: modern Various arch structures As arch construction is one of the oldest means of spanning rivers and forming the roofs of large buildings, it is appropriate that this set should start with illustrations of a number of historic arches, including Roman and Medieval. It was inevitable that the arch form should dominate the early history of building as with Read More Go to Site
