4. Objective
To propose two solutions for the design of the structure.
To analyze both solution and to adopt one solution that is
more feasible.
To make rough estimate of time for the completion of
construction works.
To determine the construction cost of project.

5. Problem Statement
■ Design of covered market with following
Specifications.
The roofed area is to be 650 x 260 feet with a clear roof height of
30’.
Entrance 10.0 ft wide are required between 23 ft long sections of
wall.
The roof is required to overhang the perimeter enclosure by
32.75 ft on all sides.
Supporting columns are to have a minimum spacing of 45 ft
internally and externally
The ground floor will be raised above general ground level by 4
inches.

6. Imposed Loading
■ Roof generally: 13 psf
■ Ground floor: 105 psf
Site Conditions
■ The site is flat.
■ The wind load on the structure can be taken as 35 psf.
■ Ground Conditions:
■ 0 ft to 16.5 ft – very soft clay and silt (Allowable soil pressure = 1 ksf)
■ Below 16.5 ft - strong limestone and hard sandstone (Allowable
pressure = 80 ksf)

7. Proposed Designs
We proposed two solutions for the design of the structure:
■ Design using steel frame with concrete foundation.
■ Design using reinforced concrete.

8. Design of light weight Steel
Structure
■ First proposed structural designs on which we decided to work was
steel design.
■ It was like a hipped roof to which a steel frame was supporting.
■ We provides 15 degree slope on each side.
■ The highest point of the slab was the middle section and gradually
decreasing towards the edges in all directions.

9. TopView
■ We drawn the whole covered area of the building inAutoCAD
software.

11. Limitations
This idea was rejected because of some limitations.
■ HighWind Load
■ Limited Software knowledge

13. Design Of Concrete Structure
■ Second proposed solution was to design it using reinforced
concrete and following the ACI code.
■ We divided our slab into small huts of sizes 49.56 x 49.85.
■ Each hut was further divided into smaller panels of sizes 15.52’x
16.44
■ By using cross beams to reduce the required depth of the slab.

14. ■ There are total 48panels and 65 columns (13 along 650’& 5
along 260’) supporting these panels.

15. Design Approach
■ The shape of the building was drawn in AutoCAD ,we divided it
into panels of 49.6’x 49.58’.
■ Each panel was of hut like shape.
■ We calculated the total load that is applied on the structure.
For example, wind load of 35 psf and imposed loading of 13 psf.
■ Slab, was divided into panels in the first step. Slab type was
coming out to be one-way.

17. ■ Load from slab was transferred on to the beam
including the dead load of the slab.
■ There are three types of beams.
■ Then load transferred from beams to columns, now
this load was including the dead loads of slab
