The backfill behind a retaining wall above the water table consists of a sand of unit weight 17 KN/m3‚ having shear strength parameters c / = 0‚φ / = 370 . The height of the wall is 6 m and the surface of the wall backfill is horizontal. Determine the total active thrust on the wall according to the Rankine theory. If the wall is prevented from yielding‚ what

members in Diagrid structures act both as inclined columns and as bracing elements‚ and carry gravity loads as well as lateral forces‚ due to their triangulated configuration‚ mainly internal axial forces arise in the members‚ thus minimising the shear effects. To begin with the behaviour of basic Diagrid module is discussed‚ followed by construction process. Then the advantages and disadvantages of Diagrids are listed. The History of the Diagrid Although the Diagrid is now seen as a modern new

2.3. Pulsatile Flow Pulsatile flow is such a flow that varies with time. Another property of pulsatile flow is that it is usually periodic in nature that is‚ a specific flow pattern is repeated over time. This type of flow can be found in the cardiovascular system of chordate animals‚ where the heart produces the pulsatile flow [9]. The phenomenon of de-polarization and re-polarization of atria and ventricles is an example to produce pulsatile flow in human hearts. An electrocardiogram (ECG) plot

The diameter of the shaft must be uniform throughout and there are two further design requirements : - the angle of twist between A and C must not exceed 1.5o; - the maximum permissible shaft shear stress is (MAX = 60 MPa. Determine the minimum shaft diameter that may be used‚ G = 77 GPa.

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
