Design Of End Girts

End girts, also known as end wall girts or end wall framing, are horizontal structural members used to support the cladding or siding at the end walls of a building. The design of end girts involves determining their dimensions and spacing to provide adequate strength and stability. Here are the general steps involved in designing end girts:

Determine the loads: Identify the applied loads on the end girts, including wind loads, snow loads, and the weight of the cladding material. Consider any additional loads specified by the design requirements.

Select girt material: Choose the appropriate material for the end girts based on factors such as structural requirements, available materials, and design code provisions. Common materials for end girts include steel, wood, or composite materials.

Calculate girt dimensions: Determine the required dimensions of the end girts based on the applied loads and the selected girt material. Consider factors such as the span length, spacing between girts, and allowable deflection criteria specified by the design code.

Evaluate girt strength: Calculate the required strength of the end girts to resist the applied loads. This involves assessing the bending moment and shear forces acting on the girts. Use structural analysis methods, such as moment distribution or finite element analysis, to determine the internal forces.

Design reinforcement (if applicable): Depending on the girt material and design requirements, you may need to consider reinforcement elements such as bracing or connectors to enhance the girt’s strength and stability. Follow the relevant design code provisions and guidelines for reinforcement design.

Check for code compliance: Verify that the designed end girts meet the relevant design codes and standards for strength, stability, and serviceability. Consider any additional requirements, such as fire resistance or seismic design provisions, if applicable.

Connection detailing: Develop detailed drawings and specifications for the end girts, including connection details to the adjacent structural elements, such as columns or beams. Ensure proper load transfer and stability at the connections.

Documentation: Prepare detailed design calculations, drawings, and specifications for the end girts to provide clear instructions for fabrication and construction.
