# Advanced Math/Building construction without Staircase.

Question
QUESTION: Dear Prof Scott

http://en.wikipedia.org/wiki/Building

Is it possible to construct a Building i.e. residential or commercial complex without Staircase ?. Is it feasible to built ?.

The people will always use Lifts / elevators instead of alternative of staircase.

i.e. The space occupied by the staircase will be replaced by additional Lifts / elevators.

What are the pros (advantages) and cons (disadvantages) if such a building model is constructed without staircase (if feasible) ?.

Examples : 10 floor commercial complex, 6 floor residential complex etc.

Thanks & Regards,

ANSWER: Yes, it is possible, but it is not done due to one reason, and that is power failure.

A really important one is in the case of fire in the building.

The power could also fail due to the weather, a car accident hitting power lines,
or something else, so it is necessary to have another form of exit.

This is why it is in the laws that any building with more than one floor is required to have a manual exit off each floor.  In some case, the building is next to a slope and has exits to the ground from differing floors.  For large buildings, they are required to have two exits.

An example of this was when the twin towers were hit in New York,
the stairways were used for the exit.

QUESTION: Dear Prof Scott

Thank you.

The Key to this Building model success i.e. Building construction without Staircases would be Elevators robust fire protection systems as well as should be in running condition even in emergency situations such as main power breaks for several days so that people should not get stuck up inside the elevator. I am confident that in the 21st century we will be able to have these modern elevators or they may be already available manufactured by Schindler, Otis etc cos.

If Modern elevators provide these capability, the staircases may not be required
in future building constructions.

It will be also interesting to have a Building Plan without staircases by the architects.

Thanks & Regards,

Yes, but have they made fire resistance wiring for the elevators, or is it too expensive.
All could be well and good in an elevator in a fire, but what about the power.

Now that I think about it, with modernization of everything, it might be possible to run an elevator just like Wi-Fi.  That is, make the elevator wireless as well.  There still might be some concerns about the motor in the elevator ... but maybe that could be made in the middle of a fireproof box ...

Perhaps the people will need to go a museum to see special things this world use to use ...
like cars that start with a metal key, lights that require a switch (you mean clapping didn't always work?), doors that use a standard key to open, appliances that require an electrical chord, plug ins, etc.  All I can say is that people in the future will look back at us just the same way we look back at history before they developed the engine or machines of mass production.

#### Scott A Wilson

##### Expertise

I can answer any question in general math, arithetic, discret math, algebra, box problems, geometry, filling a tank with water, trigonometry, pre-calculus, linear algebra, complex mathematics, probability, statistics, and most of anything else that relates to math. I can also say that I broke 5 minutes for a mile, which is over 12 mph, but is that relevant?

##### Experience

Experience in the area; I have tutored people in the above areas of mathematics for over two years in AllExperts.com. I have tutored people here and there in mathematics since before I received a BS degree back in 1984. In just two more years, I received an MS degree as well, but more on that later. I tutored at OSU in the math center for all six years I was there. Most students offering assistance were juniors, seniors, or graduate students. I was allowed to tutor as a freshman. I tutored at Mathnasium for well over a year. I worked at The Boeing Company for over 5 years. I received an MS degreee in Mathematics from Oregon State Univeristy. The classes I took were over 100 hours of upper division credits in mathematical courses such as calculus, statistics, probabilty, linear algrebra, powers, linear regression, matrices, and more. I graduated with honors in both my BS and MS degrees. Past/Present Clients: College Students at Oregon State University, various math people since college, over 7,500 people on the PC from the US and rest the world.

Publications
My master's paper was published in the OSU journal. The subject of it was Numerical Analysis used in shock waves and rarefaction fans. It dealt with discontinuities that arose over time. They were solved using the Leap Frog method. That method was used and improvements of it were shown. The improvements were by Enquist-Osher, Godunov, and Lax-Wendroff.

Education/Credentials
Master of Science at OSU with high honors in mathematics. Bachelor of Science at OSU with high honors in mathematical sciences. This degree involved mathematics, statistics, and computer science. I also took sophmore level physics and chemistry while I was attending college. On the side I took raquetball, but that's still not relevant.

Awards and Honors
I earned high honors in both my BS degree and MS degree from Oregon State. I was in near the top in most of my classes. In several classes in mathematics, I was first. In a class of over 100 students, I was always one of the first ones to complete the test. I graduated with well over 50 credits in upper division mathematics.

Past/Present Clients
My clients have been students at OSU, people who live nearby, friends with math questions, and several people every day on the PC. I would guess that you are probably going to be one more.
