Civil Engineering PowerPoint Presentations
The basic intent of this study is:
The objective of this presentation is to furnish design of curved bridges with a basic understanding of the configuration, geometric approximations and structural behavior and their interrelationship in simple structural loading system.
Why do we need joints?

Live load distribution on highway bridges is a key response quantity in determining member size and, consequently, strength and serviceability. It is of critical importance both in the design of new bridges and in the evaluation of the load carrying capacity of existing bridges.
Live load distribution is a function of the magnitude and location of truck live loads and the response of the bridge to these loads.
The construction of the Millau viaduct in the southeast of France was a colossal engineering effort. The piers rise 803 feet from ground level, and the bridge weighs 400,000 tons.
The bridge is supported by seven huge pillars. When the thickness of the platform (14 feet) and the height of the pillars are included, the total height reaches 1102 feet. That is about 50 feet higher than the famous Eiffel Tower.
Construction of this bridge required more than 350,000 tons of concrete and 40,000 tons of steel. Assembled with the precision of a Swiss watch, this giant was designed to resist winds of up to 130 miles per hour and has cost almost 300 million euros (US$523 million).
Built across the mountainous terrain of the Tarn river valley, the 8071-foot long bridge is part of the A-75 freeway that connects the cities of Clermont-Ferrand and Béziers. It will shorten by more than 60 miles the route connecting Paris with the Mediterranean.
Seven European countries participated in construction of the bridge, the design of which was the work of the prestigious British architect, Sir Norman Foster, of Manchester, England.
A column is generally referred to a vertical member designed to resist mainly compression. In building construction, columns are usually constructed monolithically with beams to form an integral structural frame. Hence, a column will inevitably, in addition to compression, have to take up bending moment transmitted from beams to which it is connected.
Therefore, unlike beam section, which is designed solely for bending, column section has to be designed for combined action of axial compression, N, and moment, M. In this chapter, the basic assumptions for beam in Chapter 2 will be adopted to derive the design charts for column, and then you will learn how to make use of these design charts to design column sections and then extend this method to design R C walls.
