Episode 103 - Space Frames, Cable Nets, and ETFE Systems

The Structural Engineering Podcast · Jan 7, 2026 · 1h 5m

In Episode 103, we dive into space frames, cable nets, and ETFE membrane systems. Joining us is Joshua Schultz, Associate Professor of Civil Engineering at Gonzaga University, to discuss the lightweight structural forms that make some of today's most iconic buildings possible. From the geometry that drives space frame efficiency to the tension‑based behavior of cable nets and the surprising performance of ETFE, we break down how these systems work, where they shine, and what engineers need to consider when designing them. Tune in to hear how these structures balance form, efficiency, and…
