To model beams and bracings for industrial steel structures using TSD

1. Create beam properties for First floor and model the beams

Ans :-

Aim :- To Create Beam Properties And Model Primary And Secondary Beams On The Ground floor , First

Floor , Roof Level

Introduction :- Tekla Structure , Basic Building Objects Are Provided And Detailed Further. Columns Beams Is

Modelled And properties Are Assigned Such as Materials , Alignments , Supports Design Code Etc. Certain

Configurations Are Assigned Before Modelling The Objects Such As Design Code , Analysis Type , Scenes , Materials

Etc.

Procedure :-

- Open Tekla Software

- Click On Mange Property Sets

- Click On New

- Select Steel Beam

- Create Three Types Of Beams And Assign Steel Beam Proprtie

- Three Types Of Beams Are taken : Beam 1 - ISMB250 , Beam 2 - ISMB350 , Beam 3 - ISMB500

- Untick Autodesign In Each Of The Beams

- Major Alignment Is Taken As Bottom In The Beams

- Now Place Beams At The First Floor

- MB 500 Beams Are Placed Horizontally On Plan

- MB 350 Beams Are Placed Vertically On Plan

- MB 250 Beams Are Placed As Secondary Beams

Results :-

2. Create rafter beam on second floor as roof and moment frame action in one direction and add bracings at

locations as per the design intent

Ans :-

Aim :- 1. Create Rafter On Second Floor As Roof And Moment Frame Action In One Direction

2. Add Bracings At Suitable Locations

Introduction :-

Bracing System : Function Of Bracing Is To Provide Stability And Resist Lateral Loads , Either From

Diagonal Steel Members Or From a Concrete ' Core '. For Bracing Frames , Beams And Columns Are Designed Only

To Support Vertical Load , Since The Bracing system Should Carry All Lateral Loads.

Rafters : A rafter Is A Structural Component That Is Used As Part Of a Roof Construction . Typically , It Runs from

The Ridge Or Hip Of The Roof Of The Wall Plate Of The External Wall .

The Ridge Beams Is The Horizontal Timber Beams At The Apex Of The Roof . It Has No Structural Function But Is

The Member Against Which The High Ends Of The Rafters Lean . It Ensures That The Rafters Meet In A Straight

Line And Stay Upright .

Procedure :-

- Go To Model tap

- Go To Manage Property Set

- Assign Properties To The Beam : Section Is ISMB 500 , Untick Autodesign , Major Aligment Is Bottom And Under

Releases Both Ends Are Fixed

- Create Another Steel Beam : Ridge Beam

- Assign properties To The Beam : Section Is ISMB350 , Untick Autodesign And Major Aligment Is Bottom

- Now Click On Frames

- Select All The Grids And Assign Frames.

- Now Open FRAME 4

- Draw Construction Line At Midpoint Between Grids E And F

- Draw Another Construction Line Above Firrst Floor Level As Show Below

- From The Intersecting Point Draw Rafter Beam Connecting To Both The End Points

- Draw Similar Rafter Beams At Remaining Grids

- Now Place Ridge Beam On Top Of The Rafter Beams.

- Go To Manage Property Sets

- Add New Member : Steel Brace

- Assign Section As : Equal Angle 75X75X8 Size And Connection As Bolted , Untick : Autodesign

- Select Brace - X From Model And Draw Bracings In Frame C And G As Shown Below.

- Go To Model And Click On Wall Panel

- Draw Wall Panels At Frame c , G As shown Below - Similarlt Draw Wall Panels At Grid 1 And 4

- Now Click On Roof Panel In The Model Tob And Draw roof Panels At Rafter Beams

- Go To Manage Property Sets

- Click On New And Create Slab item

- assign Properties To The Slab : Slab type : Slab On Beams , Decomposition : Twoway , Depth Taken As 200mm ,

Grade Taken As M25

- Untick Autodesign

- Reinforcement Details : For Tap And Bottom Bars ( Both Inside And Outside )

- Bar Size 10mm

- Bar Spacing 150mm

- After Assigning Properties , Go To Model : Click On slab On Beams.

- Assign Slabs In The Ground Floor , First Flooor And Top Floor ( Angle 90 )

Result :-
