Week 7 Challenge

1. Modelling of a structure with following details

• Bay spacing 5 m
• Span of Truss 30 m
• Shape of Truss – Pratt Truss
• Slope of truss 20 degree
• Height of the column 15 m
• Floor Beams at 5 m from base
• Secondary beams at 1.5 c/c
• Length of the building 50 m
• Column Supporting Floor Beam @ 6 m c/c Along the frame.

2. Applying Specification and member property for modelled structure.

• Columns - ISMB 500
• Truss -Top & Bottom chord – ISA 110x110x12, Diagonal member – ISA 75x75x8
• Purlins – ISMC 150
• Tie Beam – ISA 120x120x10
• Floor Primary beams – ISMB 300
• Secondary beams - ISMC 150
• Floor beam supporting columns – ISMB 300
• Assume bottom of the main column as Fixed support & intermediate floor beam supporting column as pinned
• Orient the Angle sections by applying Beta angle.

3. Creating a group for following members

• External column
• Internal columns
• Roof Frames
• Top chord of the Truss
• Primary Beams
• Secondary Beams .
