Structural Design

Excellent idea! How do you propose to solve the problem of span?

You must have some calculations that you can share.....Let us know soonest.

You've done soil compac..............................

Never mind.

Let's see what you've got.

Er Dude, I would seriously suggest you employ the services of a qualified architect who is well across the various "building codes" relevant to where ever it is you are.

Asking this question on the interweb and expecting a comprehensive answer from very random strangers (who don't have a vested interest in your success) is very wishful if not quixotic....

Building codes vary between countries sometimes even between states. So you need to engage someone professional that is "local" to where you want to build this apartment block. Anything else is an absolute liability.....

The fewer columns you have means that the price is going to increase.

The height will probably increase.

You should consult a professional architect.

I serious hope that you're not a DIY'er, 'cause you need to hire a Licensed/Registered Architect and Professional Engineer (in this case a QUALIFIED Structural Engineer).

I am a retired engineer! They all tell the truth. You, or someone, need to know the local building code--they may not follow the IBC. They must be registered, or it will be illegal. The column sizes will increase, and the soil loads will increase. The supporting beams will have longer spans, thus will have to be deeper to limit deflection and provide strength, thus the building will be taller. You will also have to provide outside parking, because the tenants may not drive vehicles that will fit the garage--my van is too tall for a standard parking garage, and the roof rack makes it even taller. With all that, the $$ will go up.

Thank you sir

Anyone else notice that the OP didn't even ask a specific question. All he did was make a statement. So ah...Sowmya, what exactly is your question?

Try a suspension type roof with columns at periphery.

Thank u very much, Since it is a G+3 Apartment will suspension roof take the load of the beams and the above floors.Pls reply

Iam not a civil or structural engineer but a suggestion only.

Well since you have reduced the number of floors to 3, that will make it much easier!

Quite simple. Design what YOU want, and then let the architect make it legal.

You may have to compromise (a little) for safety, but essentially you will get
the building you desire. (I have done this many times.)

You sketch exactly what you wish for, and the pro. builds it safe and legal.

jt.

I have morons on my team.

Thanks a lot Sir. I am very much convinced by your answer.

Hire some licensed professionals. Not doing so can lead to some nasty consequences.

Not worth getting someone hurt or killed.

designing frames, or asymmetrical structures, the solution is....

1) to separate the flexible columns, from the rigid columns
2) amortization method of seismic energy in the vertical and horizontal axis of the frame.
3) nodes to move freely round the rigid column

Oh yeah ... why columns at all - Make is all parking. Why not try a Baloon Building like in Dubai .. the Baloon city - proposal underaway! Cheers Sowmya!

EXPERIMENTthis video shows the medium accelerations .https://www.youtube.com/watch?v=8ubLKyyO2q0Even greater accelerationhttps://www.youtube.com/watch?v=zOyoEWpvsjMEven greater speed than the other two times .Look towards the end of the video that gets the beam base !https://www.youtube.com/watch?v=Q6og4VWFcGAIn this video got the beam broke the bearing of a bar that makes the transmissionreciprocating motion, and I had after 3.5 minutes that nodded to stop.The model did not suffer the slightest , the base dissipated .https://www.youtube.com/watch?v=iUH5OBd64vcno cracking ... not suffered the slightest .After the experimenthttps://www.youtube.com/watch?v=FBJi...ature=youtu.behttps://www.youtube.com/watch?v=xNfB...ature=youtu.behttps://www.youtube.com/watch?v=EnsC...ature=youtu.behttps://www.youtube.com/watch?v=7XH-...ature=youtu.be
THIRD EXPERIMENT WITHOUT THE SYSTEM SEISMOSTOP
https://www.youtube.com/watch?v=Ux8TzWYvuQ0
After the third experiment (Control structure model and base)
https://www.youtube.com/watch?v=dTBr0CtjRoM

If the system I have is strong or not, by anchoring structures will be discussed later with another different experiment .
Consider if the foundation of the project with the ground and the roof is better seismic design of the existing earthquake regulations .
Imagine that fat in this experiment https://www.youtube.com/watch?v=Q6og4VWFcGA there is only the construction and soil.
The construction in our model starts from the raft and above, and the ground of the iron based seismic and down.
I think that in the depths of a drilling anchors if the anchor is impossible for construction to pick up all this ground.
Since I consider the seismic base as ground very powerful clamping , in our experiment, think that soil is the seismic base, bearings , the W of the iron beam, the beams O.S which rests the foundation, and whatever else may be.
The model ground ( seismic base) join the tendons .
During the oscillation of the model tendons reacted to rising roof and raised the iron seismic base. The iron seismic base in turn raised his bearings which rests , bearings found resistance at the anode were in F the iron beam , and this is well anchored to the beam from the O.S lifted upwards.
All this is a result of chain torque model.

Removing the screws from the bottom of the base changed the whole scene .
https://www.youtube.com/watch?v=Ux8TzWYvuQ0

The model not having the screws to hold it began to wobble dangerously . The bearings were no longer in the upward tendency of the beam Π, because the model of oscillated only on the basis of seismic iron . Instead of upward trends bearings took percussive strokes of the oscillation of raft on the seismic base. Bearings are dyed and not withstand the impact. For this and broke .
The model does not fight happened almost anything, because it was very powerful nodes ( horizontal and vertical ) and because it was not possible to test the accelerations tested the previous experiment with the bolts , because we would have complete reversal .
The conclusion I make myself is that if the model was more multi storey would have even more sway than that of two floors .... The first conclusion is that this earthquake is very much necessary for the fine buildings to stop the oscillation from the air, and the earthquake .
If this model O.S experiment was made ​​of bricks ( bricks ) without columns, imagine for yourself what would happen if there were no screws and rods . Conclusion necessary that the earthquake in the continuous construction.
This is my opinion .... I would be happy to know and yours .
Basically what makes this invention is that it makes far more powerful rigid large vertical elements , giving them greater resistance to both cutting as well as the lateral loads .
There are many designs for installation , which depend on the architectural design needs .
