This course provides comprehensive training on wood framed wall bracing design according to the International Residential Code (2021). This is the second part of a two part series on wall bracing design.
The course covers the determination of the amount of bracing required, factors affecting the capacity of bracing, load path, wall bracing foundations and irregular structures as defined in the International Residential Code.
7 Hours [ 0.7 CEUs ]
This is an On-demand course which means that you can take it at your pace.
In this section, we will look at how designers determine the amount of bracing needed. We will look at the following:
The determination of the amount of wind bracing needed.
Wind bracing adjustment factors.
The determination of the amount of seismic bracing needed.
Seismic bracing adjustment factors.
In this section, we will cover the following:
Minimum length of bracing and contributing length.
The partial credit concept.
Spacing and location of wall bracing panels.
Minimum number of bracing panels.
Distribution of wall bracing panels.
Mixing bracing methods.
Interior finish.
Panel joints and blocking.
A project example where we will verify that a design project is code compliant with respect to the factors affecting the capacity of bracing.
In this section, we will cover the requirements for the transfer of lateral loads from the roof and floor diaphragms to the foundations. Our scope includes.
Load path from the roof to the top plates.
Load path along the top plates.
Load path from the top plates to the wall (and through upper floors) and to the sill plate.
Load path from the sill plate to the foundations.
Example project where we will verify if the load path construction details provided on a project are code compliant.
This section covers the code requirements for the construction of foundations and cripple walls along braced wall lines.
The requirements for continuous foundations.
Bracing requirements at cripple walls.
The limitations on other foundation systems supporting braced walls.
An example project on wall foundations where we will examine if the foundations provided on a project are code compliant.
In this section, we will cover irregular structures as defined in the residential code. We will cover the following:
Out of plane offsets at braced walls.
Lateral supports for roofs and floors.
Inplane offsets of braced walls.
Floor and roof openings.
Floor level offsets.
Non-perpendicular braced walls.
Portions with masonry and concrete construction.
Hill-side construction.
In this section, we will continue with the conventional structural design of a two story residential structure in Seismic Design Category D2 (Very high seismic hazard risk) and a wind speed of 120 miles per hour.
This is the final section in this design project where we will design the wall bracing at the second story and the first story. Additionally, we will develop the structural drawings showing wall bracing layouts and construction details as is typically required for permit issuance and construction.
