 Posted: Tue Aug 22, 2017 3:04 pmPost subject: design a very high rcc wall type structure |
 |
|
sir,
i want to design a concrete tank like structure. it is rectangle in shape having 4 sides are provided with rcc walls of 32m height. columns are provided at 6m c/c distance.
the load inside the tank is in linearly varying in nature having maximum at bottom. how can i start the design? please give an idea |

Dear Er.Shaji
If you have started practicing, it is better if you get associated with some senior engineer for this project
If you are a student doing a project work, my suggestion is to introduce horizontal beams at about 4 to 6m c/c
The wall panels may be designed for the average pressure in each panel, or to get more accurate result, you can split the trapezoidal pressure into a uniform pressure and a triangular pressure, both of which can be analysed.
The columns and beams can be modelled in STAAD and the reactions from the panels can be applied as loads in the appropriate directions

thank you sir for the replay
当我把墙可以作为碾压混凝土设计slab?
in that condition what are the support conditions?
can i take the moment coefficients from is 456 for uniform pressure? |

Dear Er.Shaji
Yes, you can design the wall panel as an rcc slab. If top and bottom slabs are present, there will be continuity on all four edges for all panels. For uniform pressure, moment coefficients can be from IS:456. For triangular pressure, Reynold's handbook can be referred
