EVOLUTION OF HIGH-RISE BUILDINGS 1.Historical Development In High-Rise Buildings Ancient Skyscrapers - The Great Ziggurat of Babylon Perhaps the most impressive structure in the ancient Middle East‚ the Great Ziggurat of Babylon was built over a span of several decades in the Sixth Century BC. Its seven stories‚ built upon a square foundation‚ stretched 300 feet into the sky. Some think it was the inspiration for the infamous Tower of Babel in the Book of Genesis. In this illustration‚ King Nebuchadnezzar

rotational force that occurs when force is applied at any place away from at any point perpendicularly. A bending moment will occur when a moment is applied to a system so that the system will bend. According to Hibbeler‚ beams develop different internal shear force and bending moment from one point to another along the axis of the beam due to applied loadings. A bending moment experiments may be vary according to experiments. The moment is calculated and measure as force times distance of the force applied

grades to compare different particle size distributions – from wide to very narrow. Dextrose was used because of its wide size distribution and by sieving analysis‚ sections from particle size distribution were removed to be tested in the shear tester. Sodium chloride and maltodextrin have a narrower particle size distributions and the presence of very fine particles gave us the possibility to study the effect of particles below 45 m. Three samples were tested for each flow property measurement

The longbow has been used over the years‚ first as a weapon to hunt‚ later as a war weapon‚ and now its used as a sport‚ but its physics had always been the same over the years‚ regardless of its use. This physics involves two components: bow mechanics and arrow flightBow mechanics: when an archer pulls back the string‚ he does work on the bow‚ and is converted to potential energy. Upon release of the arrow‚ this potential energy is converted into kinetic energy‚ most of which is transferred to the

True slump occurs when the concrete remains in mainly the same shape with maybe a minor slump taking place‚ and is the only test of use. Shear Slump occurs when the top of the mix comes off and slips towards the side. During a collapse slump the concrete completely falls or collapses. If the later of the slumps occur‚ in the case of the shear slump‚ a new sample should be taken and the test should be repeated. A collapse slump will show that the mixture is too wet and the workability of

Literature Review Kevin‚ this is largely unfinished with some of the journals which I have written about not being relevant. My main basis of literature review will be on Terzaghi‚ vesic‚ a thesis‚ and lau and Bolton. Terzaghi‚ K. (1943). Theoretical soil mechanics. New York: Wiley In this book‚ Terzaghi introduces the idea of bearing capacities‚ the critical load over a given area which a soil takes to fail. The concept of bearing capacities became fundamental in determining the ultimate
