Intro to Structural Analysis - Loads and LRFD

This first video in structural analysis introduces the forces of nature (loads) that structural engineers use to compute the demands on a building. These loads are considered in three different design contexts:
- Serviceability
- Strength
- Extreme Events

The Load and Resistance Factor Design (LRFD) method for Strength design is discussed in more detail, including how the variety of loads are combined and factored.

For reference, please see ASCE/SEI 7 - Minimum Design Loads and Associated Criteria for Buildings and Other Structures. Load combinations are also discussed in the relevant material-based code requirements, for example ACI 318 - Building Code Requirements for Structural Concrete.
