tennis rackets! This site focuses on damping systems in structures, mainly architectural variations of the tuned mass damper. How Tuned Mass Dampers Work A tuned mass damper (TMD) consists of a mass (m), a spring (k), and a damping device (c), which dissipates the energy created by the motion of the mass (usually in a form of heat). In this figure, M is the structure to which the damper would be attached. From the laws of physics, we know that F = ma and a = F/m. This means that when
According to the New York City weather records, the likelihood of a storm with 70 mph winds was one in every sixteen years. By taking the tuned mass damper into account, LeMessurier calculated that the probability of failure could be reduced to one in fifty-five years, but that assumed that the power to the building, which was needed to keep the tuned mass damper working, was maintained without dis...
One great barrier that has stood in front of computer programmers is that of finally realizing a dream of building a computer system that realistically models human thinking. The ethics of realizing such a dream are widely debated. Many believe it would be an extremely dangerous thing to accomplish, but that hasn’t stopped many from trying. The two main systems that have been developed so far that come closest to accomplishing this goal are neural networks and fuzzy logic control systems. This
Stiffness and comfort (steel outrigger trusses) The 101 story building, 500 meters high Taipei 101 is located in Taipei, Taiwan. Taipei 101 is the pride and identity of the people of Taiwan. The building represents “concept of striving for beyond perfection” (Taipei 101 anon 2005) as it outsmarts nature with its technological features. 101 building achieved a remarkable world record for the highest building in 2004 with 101 floors hence the name Taipei 101. Designing and building the 101 building
All humans are selfish on instinct, the will to survive being an innate trait that all humans are born with, but most people don’t give this selfishness a second thought despite having the brain power to do so. It has become so natural for people to act based on their own personal interests that someone who observes more than acts can see the consequences that come with that way of living. In my life I observe far too many people around me making selfish decisions to only benefit themselves. I can
Corvette Vs. Camaro Throughout the years, Corvettes and Camaros have ran a hard race as the ultimate sports cars. Customers have always been hungry for better handling, streamline body styles, and sheer “under your pedal” power. The question we are faced with here is which has lead this race. I. 100+ Years of Performance A. The Camaro B. The Corvette II. Handling Hardships A. The Corner Carver B. A Serious Nosedive III. Pure Power A. Corvette and Camaro Powertrains IV. A Display of Streamline Beauty
