Design and optimize typical shear, moment and Splice joints in RAM Connection for the following structure modelled in Staad Pro. Design and optimize base plate connection.
Structure: A 2D portal frame fixed support spanning 15m with a pitched roof ridge height of 12m, slope of 4 degrees. 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 4m from beam column joints. Consider a hanger beam shear connected with column support of 4m height from the splice joint with a length of 3m from beam-column corner joint carrying 5kN/m load. Use hot rolled sections.
SOLUTION:
- Create the geometry according to the data given.
- Assign the property to the member
- column: ISHB 350
- Rafter: ISMB 500
- Hanger beam: ISMB 150
- Assign the load as per given in load data.
- Dead load: self weight of a member with 1.1 factor
- Live load: 10KN/m on rafter beam & 5KN/m on hanger beam
- After applying all the loads we have to assign the design parameters to the member
- Once all the design parameters are applied, Perform analysis command is given and the structure is analysed.
- Utilization ratio of a member can be seen once a structure is analysed successfully.
- Utilization ratio for this structure is shown in below image
- Once all the member is utilised we have to design the given connectconnection template ions
- Here in STAAD connection no connection temoplates are shown the the connection is designed in RAM connection using member end forces
- SHEAR CONNECTION BETWEEN COLUMN & HANGED BEAM
- The connection is passing with the ratio of 0.4
