Is the triangle the strongest shape?
No. The Circle is. The Circle is common in all of those trusses as well, the Triangular shape is made up of tubular steel. The Circle has no weak points like the Triangle. The Triangle is weak at the center of the flat sides and the joining of the points. Unlike a Rectangle a Circle will not collapse. A Circle distributes any force applied to it across it's entire surface. Force on a Triangle is carried by it's points.
Old answer:
YesYes, it is. The triangle is common in all sorts of building supports and trusses. It is strong because the three legs of a triangle define one and only one triangle. If all three sides are made of rigid material, the angles are fixed and cannot get larger or smaller without breaking at the joints, unlike a rectangle, for example, which can turn into a parallelogram and even collapse totally. If you take a rectangle and place one diagonal piece from corner to corner, you can make that strong and stable, too, but doing that makes two triangles!! Think about it! so yes, it is the strongest shapeHow many exits in an electrical room with a 480volt 1200amp service?
Per NEC 110.26, two exits are required unless: 1) the working clearance is double what is required, or 2) there is a "continuous and unobstructed way of exit or travel"
What is romantic architecture?
Architecture that was built during ther Renaissance Period 18th century
UHm no. That's wrong. ROMANTIC Architecture would be achitecture that was built during the ROMANTIC period.........not the Renaissance.
Who designed the capital building in Washington dc?
The capital building in Washington DC was designed by Dr William Thornton. The plan had three sections to house the House of Representatives, Congress as well as the main building.
What buildings are made of wattle and daub in the Medieval Times?
Certainly a lot of peasant homes were made this way, but so were a lot of nicer buildings, both in cities and towns and in the countryside. Churches were made this way, and according to writers shortly after Augustine of Canterbury's mission to the Saxons, the oldest church in Britain was made of wattle and daub on a wooden frame.
A lot of buildings, both of the very poor and the very wealthy, were built of stone. And in certain periods, many buildings, even castles, were made of fired brick. There was a lot of variation. But I would say almost anything but a castle or the palace of a king could have used wattle and daub in its construction.

What was the Distance between the North Tower and the South Tower of The World Trade Center?
NT (known as North tower) to ST (South tower) is approx. 50 metres width, Just like a normal race pool........
But problem is: Land is not flat, It bit steep... so, Which means
50"10. That's means 50 metres and 10 degrees slope, So which means 60 metres...
ANSWER IS: 60 metres for distance from North Tower to South Tower.
When is it best to renovate remodel or demolish an old building?
There are so many variables involved with this question...the simple answer is: If the cost output to renovate is less than demolition and rebuilding, taking into account your emotional attachment to the structure and what you would potentially rebuild in its place.
If a structure still has good "bones" (framing, beams, foundation, and general squareness of structure) then you might ant to renovate. Big ticket items will be: Foundation work $20,000 to $30,000 on an average house, Electrical Upgrade $5,000 to upgrade the service panel from fuse to breakers, $10,000 to $20,000 to re-wire the whole house, roofing $10,000 to 20,000 depending on square footage and materials...so you can see how it adds up. Good value Reno projects are basements, kitchens and bathrooms...if they are crappy, gut them and replace with new stuff. Upgrading windows and doors, upgrading insulation etc. in old houses adds huge value.
You could easily sink $100K into an old house to bring it up to modern standards (insulation, mechanical, electrical) plus whatever you have to repair on the exterior. In the end it comes down to your budget and what your plans for the house are....
And don't forget to take into consideration the zoning ordinances and property restrictions. It may be cheaper to demolish and rebuild, but the difficulties in getting permission could make it a much longer process. Buildings on waterfronts and in historical areas are often restricted.
What are the restrictions for development of a grade 2 listed building?
Almost anything your local Planning/Conservation Office can dream up. There is apparently no limit to the areas the Local Authority Planners/Conservation Officers can interprete that they have responsibility for any category of Listing. The initial listing need only refer to your residence by name and include minimalist information on one feature and you can rest assured that this will be diligently applied to all aspects the that the Local Authority Planners/Conservation sees fit. I speak from bitter experience as a joint owner of a Grade II Listed residence. It really is time to shake up Local Government to make them responsible for their actions. They are reimbursed with "industry indexed" salaraies, terms and conditions, have a Gold Plated Pension courtesy of the TaxPayer and absolutely no responsibility for their actions
How are cranes removed from the roof of tall buildings?
From what I have read: The crane "grows" using a jib, hydraulics, and sections. When the building is completed, the arms are dissassembled on the roof (they may be removed by another crane attached to a truck, or by other equipment on the roof?), and the process is then reversed (each section removed floor by floor by equipment inside the building). The jib is lowered as each section is removed, until there is nothing left, and the jib assembly is removed at ground level. I may need correction on this one though
What is the place called that operas are performed in?
Usually, operas are performed in opera houses. However, operas are sometimes also performed outdoors in open amphitheatres.
There are several good websites on skyscrapers and proposed skyscrapers. I don't know the names off hand but if you type "proposed skyscrapers or future skyscrapers" and or just "skyscrapers" in google or yahoo's search engine, you should be able to find what you're looking for. I've seen plenty of info on some of the bigger skyscraper websites with info on buildings not yet built or even under construction. If that doesn't work try " future or proposed NYC skyscrapers".
Building a stairwell what are dimensions?
that would depend upon the distance between floors. with a distance of approx. 9' it would be around 37" wide and 8' long.
The floor to floor height is only 1/3 of the solution for figuring out the stairwell length. That, with the tread, will give you the angle of the staircase. The less slope of the stairs, the bigger the well size needs to be for headroom clearance at the bottom. The other thing that needs to be figured in is the thickness of the floor system. The taller the joists, the sooner you'll hit your head and so the stairwell will need to be longer. For instance, 7 3/4"riser, 10"tread and 2x10 joists the well size needs to be 118 1/2" from the stair nosing edge to the head joist. For 2x12 joists it's 121". You'll need to add a little to this depending on how you hang your stingers for the actual framing of the stairwell. Check out stairwell-lengths.com for a book on all stairwell lengths for every angle and joist size.

How do you repair red rubber bricks?
If you want a perfect match you need to allow the mixture to dry on a mortar board overnight to see if the colour is going to be right when dry. If the mixture is correct, you can then mix up a large batch to fill in the cut out or imperfections.
The brick cavity needs to be well watered to make it damp, then you fill in the hole with a semi wet mixture of the brick repair material and allow the mortar mix to soak into to the host brick. Once the surface of the repair material becomes less shiny,which means that the mix is soaking into the host brick, you can then use a piece of timber or small wood float to shape and make the surface of the repair blend in with the adjacent bricks. Do not use metal trowels to form or surface the repair because this brings water to surface and makes the material too shiny or smooth. After forming the repair to the correct shape you then need to cut around the repair material with a straight edge and a pointing trowel to form a false chase for the pointing to match up with the existing pointed courses. As the material is drying you can also carefully rub in some more ground up brick dust to blend in the colour. When you are on the final finishing of the red brick repair you must use a soft paint brush to keep all of the surfaces Matt and give the repair a blended appearance. Once the repair is dry you can carefully clean out the pointing around the brick and point up as normal. You can short cut this procedure by using red brick dust on a sand and cement repair but in time the ground/base material will show through, by using a red coloured ground/base material the repair will last as long as the brick itself. One note of caution is that red bricks are normally very brittle and if repairs are made to the brick they might break or spall on the other side of the repair if a heavy frost happens soon after the repair is made, bricks have been repaired in this way in the UK for many years. Please try not to use chemical additives because they make the repair material too hard and more likely to hairline cracking over the long term.
Red Pigment can be also used to touch up the repair but in time this will wash off, so alway try and use fine ground red brick rather than colouring.
Solid plastering is the occupation of covering surfaces and producing a finish ready for painting.
There are several methods including but not limited to;
Sand Finish - cement based product that is "floated" then "sponged" to produce a flat and sandy finish
In hot rolling mills the steel bar is passed through a high pressure water quenching system whereby only the peripheral temperature is drastically reduced while the core remains largely unaffected. On leaving the specially designed quenching system, the core heat tempers the peripheral martensite that was formed during quenching. This results in a rebar with a soft core and a uniform hardened tempered martensite periphery - a rebar with high yield strength but with extremely good ductility. Such rebars are ideal for use in high hazard seismic areas.
These bars are produced in bar rolling mills by use of the globally proven and accepted THERMEX Quenching System and Technology of M/s HSE Germany.
In the Indian Region comprising India, Nepal, Bhutan, Bangladesh, Myanmar, Pakistan and Sri Lanka, M/s H&K Rolling Mill Engineers Pvt. Ltd., Mumbai (H&K India) have been given perpetual exclusive rights by HSE Germany to Licence, sell, market, install and commission the unique THERMEX Quenching Systems. As on 1 April 2013, H&K India has received orders for nearly 200 Thermex Systems to be set up in rolling mills - of which about 29 were under excecution. The installed capacity of Thermex QST rebars in India alone is over 14 million tonnes (65% market share). Each Thermex Licensee in Indian Region is subject to strict quarterly audit. Qualified QST engineers visit each Licensee to ensure that the rebar properties are as per the strict standards laid down by HSE Germany and H&K India besides meeting the Standrards of the country.
The Thermex 500 QST rebar meets most global standards and codes and is widely accepted by leading users of rebars because of the uniform properties obtained from the various Thermex Licensees.
In India, the registered trade mark/name THERMEX is owned by H&K India as per permission given by HSE Germany.
Unfortunately, in India, these QST rebars are incorrectly referred to as 'TMT' bars. 'TMT' is an acronym for Thermo-Mechanically Treatment even though no mechanical treatment is involved in the process. This has lead to a number of improper 'TMT' rebars being sold in India with non-uniform tempered martensite periphery at the rebar cross-section - encouraged by this non-uniformity "not being a ground for rejection" as per latest rebar code IS:1786-2008!
