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

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

Optimization of design- Joiunt is optimized to the utilization ratio 0.86 as shown below-

Report- Various design data are shown below-

Report- Design results and their permissible values-

• As seen from above the Column splice joint is 86% utilizes which is less than 100% but close to it.
• Thus design is safe from geometrical consideration as well as from strength criteria
