URGENT HELP- COLUMN LAYOUT

[karma134]

Dear All,

I am a starting engineer and I wanted your views on the column layout. Basically, it is a one storied house and I wanted your advice for the layout of column. These are the few facts on the building, the external wall and partition wall are 200 mm and 100 mm brick masonry wall respectively. The owner has asked me to check 2 options which are as follows:

1. Option A : With only single storied what will be the cost.
2. Option B: With G+1 what will be the cost.( For this I am planning to provide 250 x 250 mm column)

I just wanted your views on the layout of the column for the options given. The arrangement of rooms will be same as the ground floor and the stair case will be provided outside. So you may kindly leave the staircase.

For that I am attaching a autocad screenshot. Your help will be highly appreciated.

What are the construction materials? Wood, Steel, or Concrete? Other than the 6m x 6m central area, spans are short and any number of framing schemes can be used. Can you use wood bearing walls? What is the soil or can you bear the structure directly on a concrete slab?

Lots of questions.

For a rather simple question and incomplete site information as well as use of CAPS in title (means big problem here) a useful answer is unlikely the result.

OG: I found the biggest issue was him using millimeters to 4 decimal places...

A 250x250 column sounds like concrete. That would be an unusual choice in my locale. The usual construction for a house would be wood. Whether one or two stories, the roof would probably consist of prefabricated wood trusses at two foot centers covered with wood deck, either plywood or particle board.

For the second floor, the maximum span is 5.9 m, so TJI would likely be selected to clear span. Columns would be either built up studs or Parallam and would be situated in the walls.

I'll assume that this is a concrete framed home located in a region where that kind of residential construction is common.

I general, vertical structure is cheap compared to horizontal structure. So I'd seek to minimize slab depth and then introduce as many columns as are necessary to make that that slab depth possible. From what I've seen of these structures, you'll be targeting a slab depth of 125-150 mm.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

BART: Pretty much the way I'd have framed it in this locale. TJI's or parallel chord trusses.
