What are some Geometric Buildings/Structures in Real Life? Question: I need geometric buildings/structures that are real life and need to explain why they are geometric. Real life buildings/structures, such as the Twin Towers (not sure if thats geometric) but something like that and need to understand why it is geometric. Thanks! Answer: Look at Robert Maillart bridge structure called the Salginatobel Bridge http://en.wikipedia.org/wiki/Salginatobel_Bridge The underside of the bridge is essential an arch which is in complete compression. Because of the way it is design, there is low stress in the sections due to the flexing being limited and increase in compression force. Another structure is the Federal Reserve Bank in Minneapolis. It is an inverted arch that acts in the sidewalls of the building. It act like a catanary supporting the walls meaning that it hangs like electrical wires on the side. Because it acts like this, it is in complete tension on the sides. This design allowed the building to have no columns in the parking area below the building |

Did the Japanese earthquake and tsunami hit Tokyo? What buildings or structures were not demolished? Question: What buildings or structures in Tokyo (or where it hit if it didn't hit Tokyo) were demolished because of the earthquake and tsunami? If it hit Tokyo then i already have the Nintendo building. Answer: The earthquake was felt in Tokyo but there was no damage there and there was also no tsunami damage in Tokyo. |

Can anyone link me to tutorials dealing with perspective in buildings structures and other architecture? Question: I'm having a little trouble with perspective on these things. I can fake it, but I'd like to know if there is a method to drawing structures with precision using math, a ruler, and maybe a compass. Answer: This is my response to a similar question posted a few months back: ******************************************************* Here is a link to a guide for one-point perspectives: http://www.olejarz.com/arted/perspective/ Two -point: http://mathforum.org/workshops/sum98/participants/sander s/Persp.html One, two, and three-point perspectives: http://www.khulsey.com/perspective_basics.html Good luck! |

What Techniques are used to ensure that buildings and other structures remain stable in a earthquake? Question: What Engineering Techniques have been used to ensure that buildings and other large structures remain stable in the event of an earthquake in San Francisco? Answers needed soon please. Answer: First, geologists need to be consulted, and in conjunction with civil engineers, establish a proper base for the building's foundation. In San Francisco, the dangers of building on sediments and literal trash piles (down by the Marina) are enormous - liquefaction occurs in every large earthquake. If the soil liquifies beneath your foundation, then nothing else matters, no matter how clever your building is (unless you've sunk large/many pilings to distant bedrock). You need to find the real bedrock (which, assuming you could build anywhere, is readily available). Since the motion of earthquakes is vibrational in nature, the principle of vibration isolation can be utilized to protect a building is decoupled from the horizontal components of the earthquake ground motion by mounting rubber bearings between the building and its foundation. Such a system not only provides protection to the building but to its contents and occupants as well. These systems are known as "seismic isolation" systems. They come in a few different flavors. The early systems were basically just large pans of large ball bearings that allowed a building to move on the horizontal plane. Others were basically just vertically bouncing springs. Today, the SI systems have advanced so that commonly, there is a shallow bowl-shape with rubber ball bearings between the bowl and the foundation. Because of this shape, the building can "float" over the earthquake's seismic waves, with the SI system essentially keeping the building in the same place in space, while the earth moves beneath it. Recently, dynamic seismic isolation systems are being put into place that actively react to seismic events, swinging large pendulums or other weights with high-speed, high-power, computationally-complex piston systems. These dynamic systems are exciting, because they're quite safe. From my perspective as an engineering geologist, though, I would always leave my building with a passive backup system. An active system can possible fail (no electricity, not properly maintained, etc.), while a passive system is very maintenance free, and just... works, when it needs to work. All of these methods are better than the singular construction steps of stiffened, bolted, and unbolted attempts to allow the building's skeletal structure to flex with the earthquake. All of these SI methods are also known as base isolation. Incidentally NORAD command at the hollowed-out Cheyenne Mountain, Colorado, pioneered the SI mechanisms back in the 1960s when it was completed. The area is not prone to earthquakes, but it made a prime and obvious target for a large (or multiple) nuclear warhead strike in the event of a nuclear war. The isolation mechanisms we intended to allow the entire massive internal structure to bounce and roll, taking the impact energy without significant damage. |

Does the Disabled Access tax credit only apply to modifications made to existing buildings/structures? Question: Or can expenses incurred to ensure easy access for disabled individuals for a NEW building be deducted as well? Answer: Existing only. The costs of adapting an existing structure can be significant. The added costs of compliance in a new structure (most of which need to be ADA compliant under most building codes these days anyway) is negligible by comparison. |

How Are Buildings And Other Large Structures Made Earthquake Resistant? Question: I need to know how buildings and other large structures such as roads and bridges are made earthquake proof or earthquake resistant. This is for my homework. Thanks (: I've done all the homework except that part. I have to make a leaflet, and my teacher didn't teach me that part Answer: There are 2 main approaches for making structure earthquake proof. SOme things are built with tremendous strength and mass and reinforced rigidity so that the structure will not move at all. If there is no bending there is no breakage. Other structures ae built to be flexible, sort of like a tree giving way before a wind rather than snapping. Some very large buildings and bridges are anchored deep into the ground to be rigid right from the base and flexibility is built into the building with increasing flex the higher you go. Other buildings are built sitting on huge rigid slabs without being anchored at all.. Right from the base of the building movement and flexibility are used. Which method the engineers choose to use depend on the ground they are building on and what use the structure is going to have. It is a complicated problem and often the engineers do not agree on what approach is best. And the price of the method involved is also important. Both methods work well if designed well and built well when applied to the right circumstances, the ground conditions and the predeicted strength of earthquakes are accurate. |

What are some famous tourist spots in Germany with ancient buildings/structures? Answer: Guten Tag. The Rhine Valley is full of them. Full of Gothic castles that blow your mind. The Lorelia Rock Deutsches Eck (German Corner) is the name of a headland in Koblenz where the Mosel joins the Rhine. Town of Bopard Town of Rüdesheim. ( visit Stefan's Xmas shop. Open all year round. It is magical) |

Do religious buildings / structures make you feel uncomfortable? Why or why not? Question: Do religious buildings, in general, creep you out? All types or certain ones only? Please explain. What does it mean if a person feels uncomfortable just being inside or near a religious building? Answer: It might because then a person who doesn't have the same concepts of belief may be ridiculed. |
