Residential Building Design for High-Wind Coastal Areas
In Residential Building Design for High-Wind Coastal Areas, you'll learn ...
- The three most common primary failure modes for buildings
- The four primary structural building systems used in residential construction and their relative merits
- How to apply a load path through a building to the foundation, based on site-specific design loads
- How to calculate loads and stresses at connections and components along the load path
Overview
This course will review the design process required for residential buildings (one to three-story) to withstand hurricanes and other severe natural hazard events.
The design process starts with determining site-specific design loads (forces), which is outside the scope of the course. For guidance on determining site-specific design loads, refer to pertinent sections of the International Residential Code.
After determining all of the site-specific design loads (forces), the process involves the following steps:
- Determining the building’s foundation, structural frame, and envelope
- Determining the connections between individual elements
- Determining the elevation, placement, and support for utilities
- Selecting the appropriate materials
In this course the design method is Allowable Stress Design (ASD), so there are factors of safety (FS) built into the development of the material stresses and the forces at the connections. This design method has been chosen because (ASD) continues to be the predominant design method in light-frame, residential, wood construction.
The course concentrates on determining the actual forces at connections and stresses on specific components, which are applied through vertical and horizontal load paths. The entire design process is based on the fundamental premise that anticipated service and natural hazard loads can and must be transferred through the building in a continuous path to the supporting soils.
Any weakness in that continuous path is a potential point of failure of the building, and any failure creates the possibility for large property losses and the potential for loss of life.
