Beam to column connection , end plate splice connection

4 Bolt ColumnsThe beam to column connection and the end plate splice connection can have 4 bolt columns. The program will identify all the bolts that can form a T-Stub and calculate the moment and axial resistance of the connection. The inactive bolts (that do not belong to a t-Stub) will be taken into account for the shear resistance of the connection, according to the user defined settings.

Calculation of resistance in axial force

Beam to column connections (or end plate spices) that their beams are subjected to axial forces bigger than 5% of the plastic resistance of the beam must be evaluated for their capacity in tension or compression. The program calculates the axial strength of the connection and the axial – moments interaction. The calculation is available for 2 and 4 bolt column connections.

Optimization

The calculation of the resistance of a beam to column connection is a very complicated procedure for inexperienced engineers. The program offers a very agile and easy to use auto-optimization feature. After selecting the desired reinforcements, the range of bolt rows and bolt qualities and other design criteria, the program automatically proposes a series of solutions that resist the envelope of the applied forces. Each solution is different and the user can have a visual representation of it for easier selection.

User defined calculation

The program allows the user to select between a variety of options that alter the calculation methods:

o TStub model that develops pryingforces or not

o Two different lever arm calculations for The minor bending

o Reduction or not of the strength of a preloaded bolt because of tension

o User defined criteria of the shearresistance of the connection

Welds capacity

The program uses an advanced method for determining the strength of the weldings by taking into account not only the stresses by the internal forces but also the localized stresses because of the t-Stub actions. A capacity design option for the welds is also available.

Weak axis bending

The program will calculate the strength of the connection in moment and shear in both strong and weak direction of the connection.

Shear Connections

Weak axis loading

The program will calculate the strength of the connection in shear in both strong and weak direction of the connection. The axial strength will also be calculated.

Fin plate connections

Fin plate is not a different connection type allowing the user to instantly switch between angle cleat and fin plate connection type to find the most suitable configuration.

Footing Plate

Weak axis bendingThe program will calculate the strength of the connection in moment and shear in both strong and weak direction of the connection. Furthermore the program calculates the rotational capacity of the connection for major and minor bending.

Reinforcement in the concrete socket

Adaptation of the CEN/TS 1992-4-1 and CEN/TS 1992-4-2 technical specifications. This allows the user to take into account the existing reinforcement of the foundation when calculating the anchorage strength.

Anchor types

The program offers a variety of anchor types and allows the user to design the anchorage by the T-Stub resistances instead of the anchor’s strength.
