Clip angles connection


 

The spreadsheet verifies a connection between two horizontal H beams using clip angle sections.

 

The verification is perfomed considering the Eurocode norm EN 1993-1-8:2005.


Features:

  • Sections database for beams and angle selection
  • Possibility to insert User section for primary beam, secondary beam and clip angle 
  • Section characteristics evaluation (area, Inertia moments, Bending modulus resistances, centroid axis position)
  • Possibility to introduce notches for the connected beam
  • Possibility to choose one or two angles for the connection
  • Standard steel and user defined materials
  • Graphical representation of the joint
  • Separate definition of the bolting configuration for the connection on secondary and primary beam
  • Bolts definition (characteristics and geometry).
  • Selection of connection category A, B, C, D and E as per Eurocode
  • Bolts in shear or friction working mode
  • Preload definition for bolts 
  • Graphical output of the bolting and clip angles configuration
  • Ultimate and Serviceability Limit State design loads (shear and tension)
  • Graphical output of forces on bolts
  • Prying effect evaluation for bolts connected on primary beam

CHECKS FOR SUPPORTED BEAM SIDE

  • Bolts shear resistance (individual bolt check from forces resultant)
  • Bearing resistance of the web of the secondary beam (individual bolt check from forces resultant)

  • Tension resistance of the beam (net section)
  • Beam web in tension (block tearing)
  • Tension resistance of the angle cleats in bending
  • Friction bolt resistance (SLS or SLU)  (individual bolt check from force resultant)

CHECKS FOR SUPPORTING BEAM SIDE

  • Bolts shear resistance (individual bolt check from force resultant)
  • Bolts tension resistance (individual bolt check from force resultant)
  • Bolts combined tension and shear resistance (individual bolt check from force resultant)
  • Bearing resistance of the web of the primary beam (individual bolt check from force resultant)
  • Bearing resistance of the connection angles (individual bolt check from force resultant)
  • Punching resistance of the web of the primary beam (individual bolt check from force resultant)
  • Punching resistance of the connection angles (individual bolt check from force resultant)
  • Bolts group verification
  • Shear resistance of the connection angle (gross section)
  • Shear resistance of the connection angle (net section)
