This section focuses on how plan reviewers verify the required amount of wall bracing using IRC wind and seismic bracing tables. We will learn how to review project information and confirm that the correct bracing tables have been applied based on wind speed, seismic design category, and building characteristics. The section also covers applicable adjustment factors and how to check that required bracing lengths shown on the plans properly reflect these modifications.
This section focuses on evaluating whether proposed braced wall panels qualify to count toward required bracing. Plan reviewers will learn how to verify minimum panel length requirements, apply contributing length rules, and confirm the proper use of partial credit where permitted. The review process also includes checking panel location, spacing, and distribution along braced wall lines. Additional topics include code requirements for mixing bracing methods and reviewing the impact of interior finishes and horizontal blocking.
This section focuses on verifying that a continuous load path is maintained through required prescriptive connections. Plan reviewers will learn how to review connection details that transfer lateral forces from roof sheathing to wall sheathing, from walls to floor framing, and from floor systems to supporting walls or foundations. The section also covers verification of wall-to-sill plate connections, sill plate anchorage to foundations, and top plate splice requirements. Emphasis is placed on identifying missing, incomplete, or inconsistent connection details on construction documents.
This section addresses the plan review requirements associated with foundations supporting braced wall systems. We will learn how to verify foundation details at braced wall locations, including provisions for cripple walls and narrow concrete or masonry stem walls. The review process focuses on confirming that required support conditions are clearly documented and that foundation elements are consistent with IRC requirements for braced wall support.
This section focuses on identifying irregular building conditions that affect wall bracing compliance. Plan reviewers will learn how to recognize irregular structural configurations as defined by IRC Section R301.2.2.6 and verify whether proposed layouts qualify under prescriptive provisions. Emphasis is placed on identifying irregularities during plan review and determining when prescriptive wall bracing provisions are no longer applicable and additional review or engineered design may be required.
