Prerequisite: Graduate student or Instructor permission; content knowledge of structural analysis (such as CEE 3700) assumed.

Prereqs: CEE 3700; Open to PACE students with instructor permission; Design and Technical Elective/ Design Elective (CivilE);

Analysis and design of solid and glue-laminated timber members and structural systems including tension members, beams, columns, beam-columns, diaphragms, shear walls, and connections; LRFD and ASD design methods; application of IBC for timber 1. Analyze and design timber structural members and various timber structural systems. 2. Identify and define design loads according to building codes applicable to wood framed structural systems. 3. Describe the inherent nature of solid lumber, its physical and structural characteristics together with other wood products such as glued laminated timber and plywood. 4. Analyze and design tension members, beams, columns, beam-columns, diaphragms, shear walls and connections (using nails and bolts) using both Load and Resistance Factor Design (LRFD) and Allowable Stress Design (ASD) methods. 5. Review and discuss the current developments in structural wood design and construction techniques by exploring real-world timber structures (term paper).

This course combines lecture and discussion formats. Students should expect to spend 6-8 hours a week on coursework outside of class, with additional time for the semester-long project and the term paper. EXAM AND HOMEWORK POLICIES: Make-up exams will be given at the discretion of the instructor, and appropriate documentation of absence will be required for consideration of a make-up exam. It is strongly encouraged to obtain prior permission from the instructor. Homework assignments will be assigned weekly and will be posted on the class website. No late homework will be accepted without a valid reason and there will be no make-up RATs.

GRADING: RATs (Readiness Assessment Tests) and quizzes: 5%(will be assigned periodically) Homework: 15% (will be assigned periodically) Midterm Exams: 30% (two hour exams, each counts 15%) Group Project: 25% Final Exam/review paper: 25% ---------------------------------- Total: 100% The minimum passing grade is 73%.
