Introduces the theory and practice of roof framing. Includes calculations to determine rafter lengths for slopes and spans. Addresses erecting and installing trusses and techniques for rafter installation. Prerequisites: MTH 98 or placement into MTH 65; placement into IRW 115 or WR 115. Audit Available.
Upon successful completion of this course, students will be able to:
- Apply math formulas to calculate rafter layouts.
- Classify and describe various roof types.
- Follow local building codes for roof construction.
- Analyze and build a functioning structural roof system.
- Describe the framing methods for different types of roofs.
Suggested Outcome Assessment Strategies
Outcomes are assessed through a combination of hands-on and written assessments. Priority is given to hands-on proficiency based assessment in an environment that requires demonstration of skills necessary for success in industry.
Course Activities and Design
The determination of teaching strategies used in the delivery of outcomes is generally left to the discretion of the instructor. Here are some strategies that you might consider when designing your course: lecture, small group/forum discussion, flipped classroom, dyads, oral presentation, role play, simulation scenarios, group projects, service learning projects, hands-on lab, peer review/workshops, cooperative learning (jigsaw, fishbowl), inquiry based instruction, differentiated instruction (learning centers), graphic organizers, etc.
Outcome #1: Apply math formulas to calculate truss construction.
- Understand the purpose of roof trusses.
- Identify common truss parts, including plates and connectors
