A considerable amount of research has focused on load-sharing and system effects in repetitive-member wood floor systems subject to transverse loading. However, relatively few studies have been conducted to investigate load-sharing and system effects in repetitive-member wall systems which may be subject to combined transverse and gravity (vertical) loading, and...

Performance-based design has gained interest in recent years among structural designers and researchers. Performance-based design includes selection of appropriate building sites, structural systems and configurations, as well as analytical procedures used in the design process, to confirm that the structure has adequate strength, stiffness and energy dissipation capacity to respond...
Friction dampers have been used successfully to dissipate seismic
energy in steel and concrete structures. The application is new to timber
structures. The objectives of this research were to design a slotted bolted
connection (SBC) and evaluate its potential as a passive energy damper in
timber brace.
The research was...
The objective of this project was to develop an analytical model of a light-framed wood structure using a prevalent structural analysis computer program in order to evaluate system effects and define load paths within the structure, especially under extreme wind events. Simplified modeling techniques and material definitions were developed and...
Structural design codes have evolved continuously since modern codes were established. The allowable stress design format has been widely used since the late 191h century. During the past two decades, probability-based limit states design concepts have evolved and are increasingly being used for various material and structural types. Limit state...
