To model columns for industrial steel structure using TSD

AIM:

To create column properties for different types of pedestal members and model in the grids created as per the assignment 1

Introduction:

The pedestal is the block of concrete that supports the column. It transfers the load from the column to the foundation safely. It is also provided to avoid contact between the soil and the metal element. The concrete pedestals start from the BL and end at GF level

For the above question, let us first assume the pedestal dimension and model it on the grids created as per the previous assignment

Procedure:

• Open Tekla Structural Designer 2023
• Open the file created in challenge 1
• first of allcheck the settings from Home – Settings as follows

• Click on design codes and select the head code as India.check the year of design code and change it to latest year

• click on analysis and change the settings

• Select reinforcement layout and change the bar size

• Also ensure the auto design is off

• Also check the material settings from Home- Materials

• Check the construction levels and grids. construction levels can be seen in Home > left top corner

• Create grid lines using grid option

• To create a concrete pedestal, Home – Manage Property Sets – New – Members – Concrete column

• We are going to create 2 concrete pedestals, PD of size 400 * 800 and PD1 of size 600 * 400 mm

• Check for major alignment to be at centre, releases- fixed at both top & bottom and nominal cover as 50mm
• As we check the column positioning in the previous assignment , 2 construction lines are to be drawn to place the columns

• Along grid E, place PD
• Along other grids place PD1
• Check whether the pedestals start from Base level and ends at GF level

• Note that longer dimension of the column has to be placed towards longer side

• We can also view the structure in 3D view

Result:

• The column properties are created by Manage Property Set
• The construction lines are created
• The columns are created by using Model – Concrete – Column option

2. AIM:

To create column properties for steel columns and model columns in the grid created as per assignment 1.

Introduction:

The steel column is used to transfer the loads from the steel beams down to the pedestal. ISMB sections are to be used for steel columns. The steel columns level is from the GF level till the Roof beam level RBL

Procedure:

• Go to Home – Manage Property Sets – New – Members – Steel Column
• Go to Section and modify it as ISMB 350

• Pick major alignment as centre
• Releases – Bottom pinned and Top fixed

• The steel columns in grid line C are modelled with C1 using Model – Steel – Columns
• Click on the intersecting point of the grid C to place the columns
• After placing it could be viewed in 3D also

• Another set of columns C2 of ISMB 350 but with rotation as 90 deg is to be modelled for the remaining grids

• Model C2 for the remaining gridlines/construction lines

Result:

• The COLUMN properties are created using Manage Property Set
• The columns are modelled in the appropriate grids by using Model >Steel>Column option
• Validation is done to check for any errors/warnings

3. AIM:

To create beam properties and model primary and secondary beams on the ground floor

Introduction:

Primary beams are those which transfer load to the columns. They directly rest on columns

Secondary beams are those which transfer load to another beam necessarily a primary beam. They rest on the primary beams. Secondary beams are provided to break the slab length

The beam properties are first created using Manage Property Set. Then they are modelled in the grids

Procedure:

• Model a ISMB 350 beam as a primary beam connecting columns as shown below and name it as B1
• 

• View it in structure 3D

Result:

Thus the primary beams B1 Modelled between columns 

• Validate the model once again
