Sandeep Shrestha (066/BCE/70)
Santanu Shrestha (066/BCE/73)
Shyam Kumar Sinkemana (066/BCE/80)
Supervisor:
Asst. Prof. Prachand Man Pradhan
2. Objectives
• Learn the concept of lateral and vertical loading
on the building.
• Identification of structural arrangement of the
plan.
• Modeling of the building for the structural
analysis.
• Detail structural analysis using SAP 2000.
• Sectional design of structural components.
• Structural detailing of members and the system.
3. Major Scope
• Seismic coefficient method is used
• Code of practices: IS456:2000,
IS875:1987(Part 1,2), IS1893:2000,
IS13920:1993, SP16,SP34
• The bearing capacity of foundation is assumed
to be 140 kN/m2.
• The project does not take into account the soil
pressure in elements at the basement as well
as the possible impact loads due to vehicles
4. Salient Features
• Name: Bharbhacho Complex
• Location: Dhudhpati, Bhaktapur
• Building Type: Commercial
• System: RCC framed Structure
• No. of storeys: 7
• Floor ht: 3.3m

5. Preliminary Design
• Design of Slab :
as per deflection control
Slab Depth Effective depth (d) Total depth (D)
Without secondary
beam
190 mm 220 mm
With secondary
beam
120 mm 150 mm
6. Design of beam:
as per deflection control
Beam type Width (b) Total depth (D)
Primary Beam 400 mm 550 mm
Secondary beam 250 mm 300 mm
7. • Design of column
– Loaded from slab, wall, beam and self weight of
column considered
– Factored load calculated
– 20% EQ load considered
– Equating total load with Puz=0.45fckAc+0.75fyAst
– Assuming Pt=3%
– Ag calculated and size of column adopted
Column Type Dimension (B×D) mm2
Type I 400×400
Type II 400×400
Type III 500×500
8. Manual calculation
• Dead Load
– Slab
– Beam
– Wall
– column
• Live load
• Centre of mass
• Centre of rigidity
• Eccentricity
