Designing Using LRFD Principles (2 CPD Hours)

What is LRFD? LRFD (Load and Resistance Factor Design) principles are used in structural engineering applications so structural reliability is more consistent across various materials and loading conditions. This concept becomes particularly important in performance-based design scenarios when the structural engineering solutions are required to address how the structure is used and expected to perform - and not prescriptive building codes.

This interactive, online course will review load factors, resistance factors, and reliability theory. We will also discuss the four material types (wood, steel, concrete, and masonry), looking at how each of these material standards deal with LRFD design.

By the end of this course, you will be able to:

• Identify LRFD principles for concrete, masonry, wood and steel design.
• Explain why this design method will yield more economical results when faced with a performance-based design problem.
• Select factors of safety to avoid collapse or severe structural deformation.
• Compare results of the LRFD design method with the Allowable Stress Method for a limited number of members so a cost comparison of the two solution methods can be made
