INTRO & LIMITATIONS

 

The software performs Analysis, Design, Estimation & Costing of RCC Multi-Storey Building Columns, Isolated Footings and Floors at a given Level (2D).

The Software basically requires a User to enter floor data for Joints, Columns, Beams, Slabs, Point loads & Continuity. The rest of the things are taken care of by the software.

The results are displayed in the form of BM & SF, Beam, Slab, Column & Footing Schedule, Reinforcement Summary, Quantities, Cost, Bar bending Schedule for Beams & Column Loads.

Graphics option are available for display and tabular Format is available for Editing and Deleting Data.

A User should Delete / Edit Input-Data through the various Program Options only. If any editing is done outside the design environment than Data files may become corrupted. All Data should be Strictly "Entered" as explained in following steps.

Extensive Printing options are available under each display. Printing is straight forward with default set of values ( Arial Font, 8 mm Thick, Bold, Portrait ).
Only Beam Schedule will be Printed in Landscape Orientation.

The best way to go about the software is to Mark on the Floor Plan, Joint, Beam, Column and Slab Numbers. A Joint represents a Column location or an intersection between 2 Beams. The Beams are represented by its location in the form of Right Hand Side (RHS) & Left Hand Side (LHS) Joint numbers. The Slabs are represented by LEFT BOTTOM & RIGHT TOP joint numbers. All Joints will have X & Y Co-Ordinates, Top Left corner is taken as origin (0, 0). Joint / Beam / Column / Slab numbers should start with " 1 " and should not be repeated.

The Program will generate automatic Joint, Beam, Column & Slab Numbers from the information given in Project File. Some of these Numbers / Members may not be required & shall be deleted in a systematic manner as explained in the " LEARN RCF IN 18 STEPS ".  The Final Plan Graphics should look exactly as the Floor Plan.
Cantilever beams cannot be analyzed.
Beams / Columns / Slabs shall be along two mutually perpendicular axis (X & Y). Polygonal (Multi-sided) slabs cannot be analyzed.
Only three (3) Load Cases can be analyzed per File, Viz :

● DL + LL

● { DL + LL + Wind Or Seismic End Moment (WL1). } * 0.80

Wind Or Seismic End Moment shall be entered by the user on individual beams having Columns supports.

● { DL + LL + Wind Or Seismic End Moment (WL2).  } * 0.80

Whatever will the value of WL1, the program will reverse its sign (Multiply it by
 - 1) and use it as the default 3rd Case.

● Multiplication Factor of 0.80 will be applied within the Program by default.

End Moments (Wind or Seismic) are obtained by running 2-D or 3-D Portal Frame Analysis programs separately. User may use our 2-D Frame Analysis software for calculation of End Moments.

More cases can be obtained by manipulating initial values as given in the project file or individual Beam and Slab files. For example Analysis option can be re-run with LL decreased by 0.8 (0.5* 0.8 = 0.4 T/M2). Similarly masonry thickness can be decreased or default Partition load can be changed to get desired loading on the floor. However a designer has to 1st Copy the original file in to another file (using Copy Option) & do the above mentioned modifications.

Facility to Sort Analysis results (BM & SF) in A / D Order.
 
Export to Excel :

When the " Analysis Result -> Bending Moment & Reaction " option is Run, a Text file is automatically created. This File will open in Any Text Editor. You can also Open this Text File in EXCEL.
Start Excel -> File -> Open -> Delimited ->Next : Delimiters -> Comma ->Next -> Finish.
Now you will notice that Complete Data is displayed in Excel Spread Sheet.
If more than One File is Created, Corresponding to Each of Load Cases, than Open Excel Sheet for Each File (Load Case). In Excel Sheet Editing, Deleting, Sorting, Printing & Merging of Data/Files/Excel Sheets is Extremely Easy. This way any no. of Load Cases can be Manipulated.

Similar Text files are created in " Shear Corrected BM & SF " (Design BM & SF),
" Beam Schedule ", " Slab Schedule " & " Column Loads " option for Exporting Results to Excel Spread Sheet & its subsequent Manipulation.
 
Intersecting Joints between two Beams (Main & Secondary) is assumed as Hinged. Hence no Moment transfer is envisaged.
Connection between End Column and Beam is considered as Hinged. Hence no Moment transfer is envisaged between Column and Beam. However End Moments can be applied at joints as mentioned above under Load Case WL1.
After data input, the user has to switch over to graphic option for visual checking of joints / columns / beams / slab nos. When the data is error free the user can  run the Analysis, Design and Quantity options in strict order. The various results are also available through display or print options.
Beam & Slab Design is as per IS 456 - 2000. For rigorous Beam / Slab design taking in to account Durability aspect, refer our " Super Civil CD " software.
Beam Bar bending codes and details are as per standard drawings.
Beam Width / Depth < 150 mm not permitted.
Beam Width / Depth > 3500 mm not permitted.
Links (Stirrups) Area > 22.4 cm2 for Beams is not permitted.
Beam Reinforcement > 4 % not permitted.
Slab Thickness > 600 mm not allowed.
Age factor is considered as 1.1 .
skin reinforcement is provided when web depth is more than 750 mm.
All Columns are placed Centrally with respect to Beams in either direction. There is no provision to offset the column in either direction. If the offset is large than user should re-workout the Beam Span. Column design is fully automatic, Input from the User is not required. Column Size is governed by Initial size given by the user and allowable standard size and reinforcement Percentage. Columns under axial Compression and Bi-Axial Moments can be designed.
All Foundations are designed as Isolated Footings under Pure Compression. No moments are allowed in any direction. User should Analyze all Building frames considering Base as Hinged. Isolated Footing design is fully automatic, Input from the User is not required. Footing Size is governed by allowable bearing capacity (SBC) of soil and the initial size given by the user. Footing is optimized by having offset in either direction from column as equal, hence footing reinforcement in both direction is same. Overlapping footings should be corrected by changing the footing dimension, keeping the required base area constant.
Minimum Computer RAM memory of 1 GB is recommended.
Use Laser OR Ink Jet Printer.
