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

The impact toughness (AKA Impact strength) of a material can be determined with a Charpy or Izod test. These tests are named after their inventors and were developed in the early 1900’s before fracture mechanics theory was available. Impact properties are not directly used in fracture mechanics calculations‚ but the economical impact tests continue to be used as a quality control method to assess notch sensitivity and for comparing the relative toughness of engineering materials. The two tests use

55-mile (89 km) long railroad bridge across the Bering Strait.[16] At the time‚ Strauss had completed some 400 drawbridges—most of which were inland—and nothing on the scale of the new project.[3] Strauss’s initial drawings[15] were for a massive cantilever on each side of the strait‚ connected by a central suspension segment‚ which Strauss promised could be built for $17 million.[9] Local authorities agreed to proceed only on the assurance that Strauss alter the design and accept input from several

weight of the striker corresponds to the amount of energy that is absorbed in fracture. WEIGHT HOLDER Figure 1. Schematic of a conventional Pendulum Impact Tester 1 Izod Impact Test: In the Izod impact test‚ the test piece is a cantilever‚ clamped upright in an anvil‚ with a Vnotch at the level of the top of the clamp. The test piece is hit by a striker carried on a pendulum which is allowed to fall freely from a fixed height‚ to give a blow

REPAIRS‚ REHABILITATION AND RETRO-FITTING | Significance of Ferrocement repairs | After‚ we in India‚ started manufacture of concrete in years 1930’s‚ the negative aspect of concrete started showing after sometime as below:- | - Deterioration due to poor workmanship‚ particularly high water content and corrosion of reinforcement and R.C.C. Technology being new. | - Leakages in concrete due to rain water as well as in water retaining structures | This menace become conspicuous after construction

Microscope Microscopes are instruments that produce a magnified image of a small object. They are used in many scientific and industrial applications. Some common applications for microscopes include manufacturing inspection and high-technology quality control. Specific quality control applications for microscopes include semiconductor processing‚ medical imaging‚ cell research‚ and metallurgical analysis. Microscopes are supplied in one of three common configurations‚ student‚ benchtop‚ and research

IMPORTANCE OF SELECTION The best selected pump for any duty condition may be most Hydraulically fit or with best efficiency but it may not be most suitable or cost efficient. The selection criteria must include maintainability and reliability as a foremost factors.Engineers overlook systems where the pump has to be used and lack of experience often results in under performing and oversized or wrong pumps with higher operating costs .Considering pump as a plug and play device will always add cost
