    how to design a column to up 4 metre height of 10 m3 water tanker

    • BenzuJK

      That would be complicated. Water tanks are different than regular structures, as most of the weight and bulk is concentrated at the top. 10 m3 of water would mean 10 tons of water (10000 kilograms). Add to it weight of structure, and you can easily reach and even cross 25 tons of total weight.

      You must contact a qualified engineer for this design.

      Dear Abera
      your query is not a simple one. it needs more details. apparently required structure in very heavy and it would require pretty healthy columns to support the structure. roughly each column would have to bear a load of 3 to 3.5 ton which is not a small burden. moreover, as the height required is 4 meter which is again a challenging factor is mandatory to be addressed to avoid the columns from bring slender. so it is advised to get a proper design of this facility before even thinking to construct it at site.

    Thanks for sharing this.In-situ concrete slabs are commonly used. They are a typical method of construction of RCC slabs. And ofcourse they are less expensive than the prefabricated or precast construction methods.

    Hi I have encountered a hard rock very large while excavating for building foundation for 3 storey RCC building. The rock has been found at 1.2 m depth. I am thinking of inserting Steel rods in hapazard manner before casting of the concrete and hooking it to the mesh. The width of the mesh is 1.8m. I have not calculated exactly but I think since the rock is stable it should do fine and I am thinking of using M30 for the PCC at foundation. Please advice.

    I`m from Korea, and I need some information of other country`s foundation work. Plz help me.
    In our country, we use PHC(pretensioned spun high strength concrete pile) for most building foundation construction. And there are many method of foundation work such as RCD(Insitu method), PHC pile, Steel pipe …
    I wonder how do you usually do on your work?

      Hello Manish,
      You do not require a machine for RCC construction. It is a framed construction. You only need a machine if you are going for prefabricated or precast construction.

    Hi, I’m planning on building a G+1 villa house by the sea. The structural eng decided to go with shallow strip raft foundation which would lead to partial load bearing walls.The strip raft foundation has columns which are of lesser thickness & depth, and use minimal steel than what you have in regular RCC column footings but then it goes through the entire set of house walls and is 3-4′ wide and 1′ thick with steel bars.

    Is this the cheaper than going for individual RCC footings ?? if so then by how much in % terms??

    August 8, 2012

    how shall I calculate Reinforcement detail e.g. shape of bending, cutting length while considering a footing with trapizidal section?????

    Dear Benzu,

    Can you tell me if the number of rods in the columns reduce for higher floors? I find in construction of a seven storied building, the number of rods inside a column were 11 for the ground floor whereas it has reduced to 10 for the first floor. Will it continue to be reduced for 2nd , 3rd floors and so on?

    Can the full length of the column (10′) for a particular floor be constructed at a go or it is better to construct a 10′ column in two stages, i.e 5′ each?

    • BenzuJK
      July 26, 2013

      Hello Tameem,
      It completely depends on the building plan. If the building plan is the same throughout, then the number of columns should not change from floor to floor. The dimensions of the column might change but not the number.

      Also, you can seek expert advise on the your project at minimal costs.
