Project 1_Analyze and design a steel building to 10T CRANE as per IS standard code using TEKLA STRUCTURAL DESIGNER.

Aim: To analyze and design a steel building as per IS standard code.

Given data:

• Assume the wind speed as 39 m/s.
• The thickness of the wall is 150mm.
• wall and roof loading to be considered as 1.5 KN/m^2.

Procedure:

• Open the Tekla software.
• To define construction levels.
• Click on the construction levels icon in the model toolbar.
• Define the levels as per the details given in the cross-section.

• To define gridlines.
• Click on the gridlines icon in the model toolbar.
• Specify the first point and draw the first grid line.
• Then select parallel quick option and draw all other gridlines by specifying the distance.

• Go to home>manage property>define pedestrial column.

• Model-concrete column>click on grids to add
• Define the steel column of ISMB suitable size.
• From model toolbar>steel column>click on grids

• Define beams for the ground floor and model beams where required.
• Similarly, model the beams for the first floor.

• Now add the frames at each grid for adding braces and loading purpose.

• Define rafter beams and model the roof truss.
• Define a rafter for modeling on the roof.
• Define steel bracing and add at required places.

• Define slabs for all the floors, and model them based on the size of beam connection.

• Define brackets to carry the crane load and model them on the first floor.
• At last modeling, part is adding wall and roof panels to ease aplication of wind load.

• Once the modeling part is done, the calculation of loads, defining in software and applying them.
• Define the load cases and generate load combinations.

Calculation of loads:

Dead load:

• Finishing load (50mm thick)-0.05x24=1.2kn/m^2.
• Brickwall+cement plaster thickness=150mm.
• Unit weight of brick wall=20kn/m^3.
• Brickwall load on ground floor=0.15x5x20=15kNm.
• Brickwall load on the first floor=0.15x7x20=21KN/m.

Applied the loads on the ground floor, in the load toolbar>select area load and enter 1.2 as finish load.for brick wall load, select full udl load and enter values as per caluculation.

Crane load calculaton:

Result:

• Given the plan is analyzed and the column is decided.
• The structure is modeled using the model toolbar and the property of an element is defined in a property manager.
• Load is calculated and applied to the structure.
• The model is analyzed and the failure beams are resized.
