TH02 - Sizing and Placing Concrete Deck Footings - Codes and Best Practices

Thursday, October 11 from 10:30 AM to 11:30 AM « Back

Concrete deck footings are an industry mainstay but are often undersized or oversized. Learn two methods to right-size footings to adequately support a deck, tributary load calculation, and footing tables for comparison. Learn how to determine the soil bearing capacity. Moreover, learn best practice footing forming and pouring tips to ensure a stable deck.

Topics Include:
Soil bearing capacity (IRC code table).
Soil bearing capacity (penetrometer measured) Calculating tributary load on a footing.
Footing size calculations based on tributary load and soil capacity.
Footing size based on footing tables.
Best practice footing forming and installation Alternative footing types/systems.

Learning Objectives:
1. Calculate tributary load on a deck footing.
2. Determine deck footing size using the 2018 IRC and DCA 6 tables.
3. Avoid pitfalls of poorly installed deck footings.
4. Determine whether a deck needs footings that reach to frost depth.
