Determination of Site-Specific Loads for
Residential Buildings in Coastal Areas
Jeffrey Havelin, P.E.
Overview
This course will review the
procedures and formulas required to determine the appropriate forces which
residential buildings could become subjected to during hurricanes, earthquakes,
tsunamis
and other severe
natural hazard events. The design procedures required to determine the site
specific design loads (forces) which will be applied to the structure, is the
basis of this course.
Various case studies of
residential buildings will be analyzed with sample calculations demonstrating
the procedures are covered in this course.
The design professional should be familiar with the 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. Specific sections of the code and
tables have been referenced in these various sources; calculations outside of
the confines of this course would require these reference materials, however the
various references would not be required to complete the test for this course.
-
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 starts by determining
all of the site-specific
design loads (forces):
-
Dead loads
-
Live loads
-
Snow loads
-
Flood loads and the
various components
-
Tsunami loads
-
Wind loads and the
various components
-
Earthquake (seismic)
and the various components
The
student must take a multiple-choice quiz consisting of thirty (30) questions at the end of this course
to earn PDH credits.
Specific Knowledge or Skill Attained
This course teaches the
following specific knowledge and skills:
Determination of
various types of loads which could be applied to a one to three-story
residential buildings during hurricanes earthquakes or other severe natural
hazard events,
which would include
• Dead loads • Live loads • Snow loads
Detailed
formulas and procedures for determining the various components of Wind, Flood Tsunami,
and Seismic loads as follows are included in this class:
-
Determine Lateral Hydrostatic Loads
-
Determine Vertical (Buoyant) Hydrostatic Force
-
Determine Breaking Wave Load on Vertical Piles
-
Determine Breaking Wave Loads on Vertical Walls
-
Determine Hydrodynamic Load From Flood Flows
-
Determine Debris Impact Load
-
Estimate Localized Scour Around Vertical Pile (Non-Tsunami Condition)
-
Estimate Localized Scour Around Vertical Enclosure (Non-Tsunami Condition)
-
Seismic Base Shear by the Simplified Analysis Procedure
-
Vertical Distribution of Seismic Forces
Fact:
The
National Flood Insurance Program (NFIP) regulations state that for buildings in
V zones, “a registered professional engineer or architect shall develop or
review the structural design, specifications and plans for the construction, and
shall certify that the design and methods of construction to be used are in
accordance with accepted standards of practice” for meeting the provisions of
the NFIP regulations regarding buildings in V zones.
