Nonlinear modeling of structures is essential for understanding real structural behavior beyond linear assumptions. In this lecture, we explore nonlinear structural analysis from fundamentals to practical applications, focusing on structural engineering and civil engineering practice.

This video explains why linear analysis fails when structures experience cracking, yielding, large deformations, P-Delta effects, and seismic loading. Using simple beam and frame examples, the lecture clearly demonstrates how real load–deformation behavior deviates from linear predictions and why nonlinear modeling is critical for performance-based design and structural assessment.

You will learn:

What nonlinear modeling of structures really means

Differences between linear vs nonlinear structural analysis

Material, geometric, and boundary nonlinearities

Moment–curvature behavior, plastic hinges, and fiber modeling

Lumped plasticity vs distributed plasticity approaches

Application of nonlinear modeling in earthquake engineering

Why nonlinear analysis is essential for existing buildings, seismic evaluation, and performance-based design

Practical modeling concepts using FEM-based structural software

This lecture is highly valuable for:

Structural engineers

Civil engineers

Graduate students in structural & earthquake engineering

Professionals working on seismic design, retrofitting, and nonlinear FEM analysis

If you are looking to understand how nonlinear behavior develops in real structures and how engineers model cracking, yielding, stiffness degradation, and collapse mechanisms, this video provides a clear, concept-driven explanation grounded in real engineering practice.
