Episode 116 - Nonlinear Twists: An Easy Path into Complex Structure

In Episode 116, we explore the world of nonlinear structural analysis and performance-based seismic design. We discuss when nonlinear methods become necessary, how pushover analysis helps engineers understand building behavior beyond elastic limits, and where these advanced tools fit within modern codes and standards.

The conversation covers modeling challenges, common misconceptions, software workflows, seismic performance objectives, and real-world applications where nonlinear analysis can fundamentally change design decisions. We also look ahead to how increased computing power, AI, and evolving design practices may make advanced analysis more accessible to the next generation of structural engineers.
