This program introduces basic design and construction methods for single-story residential wood decks focusing on the significant changes for the 2018 IRC. The vertical and lateral load paths of conventional residential decks are addressed in the 2018 International Residential Code.

Specific design guidance includes convenient span tables for joists and beams and charts of post sizing limitations and connection methods. Figures for multiple lateral connections make connection to an existing dwelling simpler and require less removal of existing materials.

Learning Objectives:

1. Identify vertical and lateral load paths of conventional residential decks
2. Identifying the minimum footing size and materials per 2018 IRC
3. Determining appropriate beams and joist span lengths using IRC provisions
4. Determining lateral connection options for the deck to existing dwelling based on IRC requirements
