Abstract:
A review of the structural performance of single-family,
wood-frame houses is presented. The performance of these
structures in selected earthquakes and hurricanes is
summarized. In general, wood-frame houses performed well
with relatively few instances of structural failures and
without serious loss of lives. Failures mainly resulted
from poor construction practices and noncompliance with
building codes. The issue of repair costs due to
non-structural damage suggests that different
performance objectives are needed for residential
structures. The review of experimental research covers
studies on full-scale houses, shear walls and
intercomponent connections. The database for full-scale
house tests is sparse while there are numerous studies
of shear walls and only a limited number of studies on
intercomponent connections. Test methodology for shear
wall tests has evolved from prevalent use of ASTM
Standard E72 to more frequent use of ASTM Standard
E564-76. Within the last ten years there have been
adaptations of E564 for cyclic and dynamic test
procedures: however, the wide variation in test
procedures for cyclic and dynamic tests points to a need
to standardize these procedures. The development of
analytical procedures to predict component and
structural behavior under different types of loading is
also presented. It is found that while significant
progress has been made in recent years in analytical
modeling of shear walls and horizontal diaphragms, only
limited progress has been made on the modeling of a
complete house and intercomponent connections. Most of
these analytical procedures are used primarily as
research tools rather than design tools. Based on this
review, a multi-year research program is proposed to
determine the baseline performance of single-family
houses.
