Project 2_Analyze and Design the RC office building as per IS standard code in TEKLA STRUCTURAL DESIGNER

PROJECT 2

AIM:

• To Develop general arrangement for the RC office building.
• To analyze and design the building as per IS standard code in TEKLA STRUCTURAL DESIGNER.
• To generate report of each member and to extract drawings for structural plans, beam reinforcement details from the software

INTRODUCTION:

      Tekla Structural Designer is used for analysis and design of structures. The first step is to model the structure,then to apply dead load,live load, wind load, seismic load over it and to study the response of the structure. The response of the structure can be its deflection, shear force or bending moment. Accordingly suitable measures are taken. Finally all the members are checked for failures.

PROCEDURE:

• Launch TSD
• Go to Home – Settings to check the default settings

• Go to Model – Construction levels to create 4 levels – Base, GF, FF , RF

• Model – Grid lines to draw the grid lines

• Draw parallel grid lines at 6m spacing

• Now draw horizontal grid lines by using perpendicular option

• Home – Manage Property Sets

• Go to Base level
• Model – Concrete column and start placing columns in the grid intersections

• Then place the beams in the ground floor

• Repeat the same for first floor too

• Go to Construction levels and set the roof level source as first floor
• Later delete the portico beams by changing it to unique again

• Now when you try to delete the portico beams notice that the first floor beams also get deleted
• So change the RF source to unique and then delete the beams

• Now model secondary beams by drawing appropriate construction lines

• Similarly move to the FF and RF level and model secondary beams

• Validate the model for any errors in beams / columns
• Now lets model the staircase beams
• The inclined planes are first created connecting the GF beam and the midlanding beam as shown

• Connect GF beams with the FF beams

• Now draw one more IP connecting midlanding beam and FF beam
• Draw beams connecting both floors as shown below

• Repeat the same procedure till roof is reached

• Now select all the inclined beams,Edit – Copy, Pick the reference point and copy the beams to grids 5 and 6

• Now slabs on beams are modelled

• Similarly slabs are modelled for the staircase beams too

Load Calculations:

Dead Load:

• Lets now apply the floor finish load and brick loads to the panels and members

• Repeat the procedure for first floor and roof floor also

Live Load:

• Apply the live loads for each and every levels

Wind Load:

• Create Frames and then model the wall and roof panels

Calculations:

On Walls:

On roofs:

• Go to Load – Loadcases and add the wind loads

Wind + Y + Cpi:

On Walls:

On Roofs:

Wind + Y – Cpi:

On walls:

On roofs:

Wind + X + Cpi:

On walls:

On roofs:

Wind + X – Cpi:

On walls:

On roofs:

Seismic loads:

• Load – Seismic load – Seismic wizard

• Now the combination generator opens.

• Now also generate the wind load combinations

• Also apply staircase loads of 4 kN/m2

Analysis:

• Analyze – 1^st order analysis

Deflections:

BMD:

SFD:

Member Design:

Slab:

• Right click on the slab and select check panel

• Now increase the bar size and decrease the spacing to pass the slab

• Using Review – Copy properties , copy the property of the slab that has passed to all the remaining slabs and check panel one by one
• Similarly repeat for all the slabs

Beam and Column:

• Click on any frame
• Right click on any beam – Interactive design

• If you see that a member fails in other checks, click on check

• Notice that the section fails by torsion

• Notice that by increasing the b and d, the UR can be reduced
• So try increasing the size of members

• Now check the member

 

Other checks failing

• Note that the link checks are failing

• Now click on Check

Foundation design:

• Go to Base level to design the foundation
• Foundations – Catalogue

• Then pick the column one by one to place piles

• Now right click on every footing and check the member
• Adjust the no of piles accordingly

Report generation:

• Go to any floor, right click any member- Report for member
• Member report

• Model Report – Choose the information to be added in the report and Show report

• Go to Draw – Settings
• From the Layer configuration tab, check the available configuration – General Arrangement
• We can also select the desired colour from the colour palette available

• Go to a particular level and click on General Arrangement

Beam reinforcement:

Result:

Thus a thorough analysis and design of a industrial structure has been carried out by following the below steps:

• Modelling grid lines
• Modelling concrete columns from the ground floor
• Modelling concrete beams(primary and secondary)
• Modelling slabs
• Modelling wall and roof panels
• Applying dead loads (floor finishes load to floors, brickwall loading, roof level loading)
• Applying live loads to each floors
• Applying wind loads in both X and Y direction
• Generating seismic loads
• Generating load combinations
• Running the analysis
• Checking the deflection
• Checking SFD and BMD
• Slab design
• Interactive design of beams and columns
• Footing design
• Report generation
• Generating plan drawings and beam schedule
