Project 2 - Review of Shear, Moment & Splice connections in StaadPro Connection Module

1. Q. Design and optimize typical shear, moment and Splice joints in Staad Connection module for the following structure modelled in staadpro. Generate Report.

Design and optimize braced connection (use US standard connections) in RAM Connection. 

Structure: A 2D portal frame fixed support spanning 15m with a pitched roof ridge height of 12m with eaves Height of 11.5m. A uniformly distributed load of 10kN/m is applied on the roof beams. Optimize the beams and columns for 85% utilization and consider splice joints at 6m from base and 3m from beam column joints. Consider a hanger beam shear connected with column support of 4m height at 3m from beam-column corner joint carrying 5kN/m vertical load and 5kN horizontal load, hanger beam end is tied with a brace to the eave. 

Aim :

• To determine the Typical shear, moment and Splice joints in Staad Connection module for the following 2D portal framed structure modelled in staadpro are required to be designed  with following inputs/data-Also report to be Generated.

Given data:

• Supports o 2D Frame                      :    Fixed support
• Spann                                               :    15m
• Roof                                                :    Pitched roof
• Ridge height                                     :   12m
• Slope                                                :   4 degrees 
• Load                                                 :   UDL of 10 kN/m on roof beam
• Stees Section                                    :   Hot rolled
• Splice joint location                          :   At 6 m from base 
• Hanger beam                                     :    Shear connected with column support of 4 m height from splice joint with a length of 3m with a beam column corner joint carrying 5 kN/m load and 5 KNhorizontal force 
• Also Design and optimize base plate connection. Optimise beam and column for 85% utilization

Procedure :

2D portal frame as per given data  and loading is shown below-

3D view of 2D portal frame- 

Load assignment 

(i) Dead load-Self weight

(ii) Live load- 10 KN/m on roof beam

(iii) Live load- 5 KN/m on hanger beam

(iv) Live load- Horizontal force of 5 KN

Joints are created and will be designed one by one in the steps to follow[-

Up to the steps  are common to all joint design

DESIGN OF COLUMN SPLICE JOINT AT NODE NO. 7 BETWEEM MEMBER 1 & 8
