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 required calculations for all of the site specific design loads (forces) which will be applied to the structure is not within the scope of this course, however these site specific forces, which have been previously calculated in a case study, will be used in this course to design a structure that can withstand these forces.
To determine these site-specific design loads it is suggested that the design professional should refer to pertinent sections of the IRC 2000, in addition to those sections of the IBC 2000 which may be cited within this course. Additional reference sources should also include one or more of the following sources in high wind zones.
- Minimum Design Loads for Buildings and other structures (ASCE 7-98)
- American Forest and Paper Association (AF&PA) Wood Frame Construction Manual for One and Two- Family Dwellings (WFCM)
- Southern Building Code Congress International Standard for Hurricane Resistant Residential Construction (SSTD 10)
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 design process involves the following steps after determining all of the site-specific design loads (forces):
- 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
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.
The student must take a multiple-choice quiz consisting of sixty (60) questions at the end of this course to earn PDH credits.
