To model beams and bracings for industrial steel structures using TSD

Model Beams and Bracings for Industrial Steel Structures Using TSD

 Aim: To model beams and bracings for industrial steel structures using TSD

Indroduction: General Arrangement: 

. Planning column positions in the layout as per intput drawings considering the openings.  To provide expansion joints as per IS: 800:2007

. Provide primary beams to tie columns and break the effective lenght

. Provide seondary beams to syupport floor and brick wall.  Model slab on beams

. Plan the moment connections framing and provide bracing bracings for lateral stability

 Modeling: Start by creatuing a new model with the desing codes and parameters set as per codal provision

. Setting and materials commands on the HOME ribbon tab to be reviewed to ensure the required options are selected

. Define constriction levels indicating the spacings of the floor as per the architectural drawings.  Here we have a Challenge-2 Drawing have  3 Level from ground floor

. The spacing from ground to first floors is 5.2 meter and first floor to Top roof Beam level is 6.8 m, then Top Roof Beam level to Top Roof Level is 4.880m

. Column & Beam Creating: Creati coumn property (size, height, grade of steel) using properties window. The properties to be created using manage property for each type of column.

. Select plan view to model the columns

. Define and review the properties of the column

. Insert columns on grids or constrcution lines as per the planned generalk arrangement

. Model promary and secondary steel beams using storey level on plan. Manage properties beam and assign the properties to each type of beam

. Rafter:A rafter is a structural component that is used as part of a roof construction. Rafter are generally laid in series, side by side, providing a base to support roof decks, roof covering 

. Bracing: A roof truss is made of several pieces of steel that are joined together.  Each piece of the truss is referred to as a Member. A brace is a member that prevetns a structural element from buckling  or racking.

. Purlins: A purlin is a longitudinal, horizontal, structural member in a roof

. Then Edit (Fn+F2)

. To give the Offset value oh 2.66 Each Beam

To Creat the Staircase Spacing: Similarly To creat the Construction line for to providing Staircases Space on Frst Floor

. Now to creat the Secondary beam Construction line

. Select the Parallel(Quick)

. Then Edit (Fn+F2)

. To give the Offset value Of 3m Distacne from 1st Grid line

. Now to Creat the Secondary Beam by using Propertiess of B4

. Now Go to the Model Tab

. Slect Steel Beam--> Select Properties of B4

. Pick Point 1

. Pick Point 2

. Escape

. Similarly  All the First Floor beam are created By using B4 Properties As Shown in Below Diagram

 Step-5

To creat Frames:

. Select The Frame Option Form Under the Model Tab

. Then Pick The Grid Line for Given Diagrame of ou plan 

. Pick the Grid Lien 1, 2, As shownin below Diagram

. Similarly All remaining Grid Line of 3, 4, and A-G Gird line as gioven below diagram 

. Press Escape.
