LEARN COMPOSITE STEP BY STEP
STEP NO. 10
 Beam Design, Quantities, Cost Estimation
and Column Loads
 
After entering Data & Checking it thoroughly, Relax, let the software do its Job.
The 1st milestone is Analysis.

When Program starts, the Menu above is displayed.
Under the Beam + Column Design + QTY Heading following options are displayed.

● Beam
● Beam Log File
● Column Loads
● Script
● Column
● Column Log
● Standard Details
● Quantities


Now Click on " Beam " Option.

Following Graphics is displayed.
 
Now select " Example _1 File & Press Open Button.
Following Warning is displayed.
This is a very Important Message. In case a user has edited or added any Joint / Column / Beam or Slab Member after performing analysis then he should re-perform the analysis, else old (in-correct) results will be displayed.
However Re-Analysis is not required for Beams Provided:
● Only Beam Type & Section is Changed.
● Project File Parameters are Changed.

Re-Analysis is required for Beams if Loads & Floor Geometry is Changed.

Click " Yes " if you have not revised any member after analysis or click " No " if you are not sure.

If " Yes " is clicked then following message will be displayed.
 
 
Now Click the " Log File " Button. Following Design Results (Part) is displayed. The LOG file will display Beam results (Safe / Unsafe) & various parameters on which Beam is evaluated. User should study the each parameter in order to redesign the beam for safety or for economy / Optimization.
 
The Composite Beam Design is carried out as per following Codes,

Construction Stage:

As per IS 800 : 2007.

Composite Stage:

(a) Section Classification and BM as per Euro 4.

(b) SF, Axial Load, Deflection, Slenderness, Bolt, Weld Design as per IS 800 : 2007.

 
Profile Deck design by Deck manufacturer.
 

 

Note that Step by Step design is given for Construction & Composite stage. If Beam is Unsafe, all the parameters will be displayed indicating why beam is unsafe. A designer shall study & correct the various parameters such as Concrete Grade/ Concrete thickness, Profile Depth / Thickness and Beam Size.
Now Click " Quantity " Option. Following Graphics is displayed.
Now Double Click " Floor Beams + Slabs " Option. Following Graphics is displayed. (Quantities and Cost of Column Project and Total Project will be discussed in later Steps).
Now Double Click " Quantity, Cost Summary " Option. Following Graphics is displayed.
DISPLAYING QUANTITIES AND COST SUMMARY
The above display gives cost summary as per the Rates Put-In during creation of Project File.
Now Double Click " Structural Steel Summary " Option. Following Graphics is displayed.
Note that the above steel weight does not include end connections & member splice. We have taken C/C distance between columns as member length, which may offset the connection + splice weight.
Now Double Click " Column Loads " Option from the Main Menu. Following Graphics is displayed.
UN-FACTORED COLUMN LOADS
PART DISPLAY
The above Column Loads Graphics is self explanatory. Self Weight of Column is not included.
When " OK " button is clicked following vital Statistical Check is displayed.
The Difference should not exceed say 10 %. 
The major difference should calls for closer look at the Data-Input.
When " OK " button is clicked, following Important Message is displayed.
The above message describes how any number of Load Cases can be Run & Manipulated once the File is Exported to Excel Spread Sheet. Note the File Name Carefully.
Click " OK " button.
Now we have come to the end of Step # 10.
Let us proceed to Step No. 11.
 
STEP NO. 10 IS OVER.
