TTT Limit States Level I is an introduction for wood truss design technicians, estimators, and salespeople to acquire the design and engineering fundamentals of metal plate connected trusses. The course uses metric measurements and references to the 2005 National Building Code of Canada. Students will be expected to perform calculations, solve problems, review presentations, and respond to interactive quiz questions interspersed throughout the sections. The purpose of the course is to examine industry design standards and factors affecting truss fabrication from design to installation and to prepare truss technicians for the Level I Certification Exam.

Upon completion of this course, attendees will have a better understanding of the truss design and manufacturing process, the application of trusses, basic math, trigonometry and load development as it relates to truss design.
