Design Best Practices for Mid-Rise Light Wood Frame Structures
Course Overview Light wood frame (LWF) construction is an accessible, cost-effective, low-carbon solution for mid-rise multi-family buildings. This session will clarify fundamental differences in approach between traditional low-rise LWF construction and modern mid-rise construction methods. LWF is an attractive option for mid-rise development and participants will gain practical insights into design efficiencies, from meeting seismic demands and other key structural considerations to how engineered wood products and specialty hardware can be used to optimize design. The session will also explore prefabrication strategies, highlighting the challenges and opportunities offsite construction presents for streamlined, higher-quality construction. Whether attendees are new to mid-rise wood design or looking to optimize their next project, this session will share valuable information they can apply to their next mid-rise building. Learning Objectives Distinguish key differences between traditional low-rise and modern mid-rise light wood frame construction, including changes in design loads, seismic requirements, and code updates. Apply practical design strategies to optimize mid-rise wood structures—such as efficient stacked framing, engineered wood products, specialty hardware, and solutions for wood shrinkage and differential movement.

Aspen Art Museum: Creating an Innovative Wood Structure
Course Overview The Aspen Art Museum, designed by architect Shigeru Ban, includes a long-span three-dimensional wood space-frame roof. Ban’s charge was to create a wood space frame with spans of more than 50 feet and cantilevers of 14 feet, in a structural depth of 3 feet. The space frame was to have two planes of intersecting diagonal webs of curved members that undulated up and down to touch the planes of the top and bottom chords with no visible connectors. This case study presentation will describe the design and construction of the wood structure, including paths explored but not chosen for the final design. Learning Objectives Articulate the particular demands associated with creating a 3-dimensional space frame entirely in wood. Recognize the advantages and disadvantages of several wood connection strategies in space-frame structures. Be aware of manufacturing capabilities and limitations that influenced the design of the Aspen Art Museum roof structure.
