Project 1

1. Design a multi-storey Residential Building located in Bangalore using STAAD Pro Connect Edition. The specification must be as follows:

Building floors	G + 6 + R
Plan dimension	B = 25m , L = 16m
Storey Height	h = 3.5m
Soil	Hard soil
Use	Residential Purpose
Safe Bearing Capacity	180 kN/m2
Maximum slab thickness	150mm

Assume suitable sections for structural elements. Follow IS456, IS1893 and IS 875

1. Prepare a Design Basis Report for the project
2. Create structural model using STAAD Pro Connect Edition
3. Prepare DL, LL, WL and EQL load calculations as per IS 875 standards
4. Design slab element using MS – Excel
5. Design beam and column element using STAAD RCDC. Attach the design calculation report.
6. Design Foundations using STAAD Foundation.
7. Prepare bar bending schedule for beam and column using STAAD RCDC
8. Attach necessary sketches and drawings wherever required.
9. All stipulations, assumptions and design parameter must adhere to Indian Standards.

Aim:- To design a multi-storey Residential Building located in Bangalore using STAAD Pro Connect Edition

Procedure:-

Unit weight of the materials

• Reinforced Cement Concrete = 25 `[kN]/m^3`
• lain Cement Concrete = 24 `[kN]/m^3`
• Cement Concrete Screed = 20 `[kN]/m^3`
• Cement Masonry Units =22 `[kN]/m^3`
• Structural Steel = 78.5 `[kN]/m^3`
• Soil =18 `[kN]/m^3`

Dead Load

Floor slab

• Slab weight = 3.75 `(kN)/m^2`
• Partitions = 1.5 `(kN)/m^2`
• Floor Finish =2.5 `(kN)/m^2`
• Miscellaneous =1 `(kN)/m^2`

Total Floor Load = 8.75 `(kN)/m^2`

Roof slab

• Slab weight = 3.75 `(kN)/m^2`
• Insulaions and Water Proofing = 0.5 `(kN)/m^2`
• MEP Services = 0.5 `(kN)/m^2`
• Miscellaneous = 0.5 `(kN)/m^2`

Total Roof Load = 5.25 `(kN)/m^2`

Live Load

Floor slab

• Common Corridor = 3 `(kN)/m^2`

Total Floor Load = 3 `(kN)/m^2`

Roof slab

• Accessible Roof = 1.5 `(kN)/m^2`

Total Roof Load = 1.5 `(kN)/m^2`

Step.1 Geometry Creation

Step.2 Assign Properties

• Column Size Set as-------->0.6*0.6
• Beam Size Set as---------->0.4*0.25

Step.3 Assign Material

• Assign Material as concrete

Step.4 Creat Support Condition

• Creat support Condition as Fixed
• And assign it at the appropriat position

Step.5 Assign the Loading

• Wind load Deination Created.
• Add the Intencity of Load with respect to the Height.
• Add the Exposure Factor as 1.

• Add Sesmic Defination as per the Codal Value

• Add the Load for the Sesmic Condition

Step.6 Add Load Combination

• 1st add Sesmic Load Condition as per the Code
• Add Sesmic Load for +X ,-X ,+Z, -Z

• Add Dead load for the Structure

• Add Live Load For the Structure

• Add Wind Load For the Structure
• Add wind load in +X,-X,+Z,-Z Direction

Step.7 Add the Mannual Load Combination As per the Is 456

• Assign the Structure

Step.8 Analysis the Structure

• Click on No print Option
• Go to Post Processing Mode

Step.9 Add Design Data for Concrete design

• Select meterial as Concrete
• Select the Concrete Code as IS 456
• Add the Design Data

• Assign the Design data for the Respected Member

Step.10 RCDC Design For the Structure

Design the Beam Using RCDC

• Select the General And Reinforcement Setting and Assign the Data

• Select the Cutailment Setting and assign the Data

• Select the Bending And Axial Force Design in the General And Reinforcement Setting and assign the data

• Select the Basic load case and add it

• Select Load Combination and Select Add for Analysis

• Select the Required Rebar setting Click Ok

• Design the Structure

• Go to BBS and Geting diagram For Beam BBS

Design For Column Using RCDC

• Go to Reinforcement Seting abd Select the Appropriat Data

• Craet the Design Seting For the Column

• Select Design the Column and Select the BBS for Column

• BBS For the Column

Foundation Design

• Select Unfactored Load Combination From the Staad Model File and go to STAAD foundation Design
• Generate the Load Combination as per Indian Standard Code

• Creat Job For by Selecting Mat Foundation

• Add Mashing Region as Rectangular

• Analysis the Foundation Model the I created.

BBS Drawing

• Beam

• Column
