Geometric Nonlinearity

An advanced course with various theoretical contents, exemplified with problems and solutions in SAP2000, which starts with the most basic concepts of geometric nonlinearity and progresses to more complex problems with cables and local post-buckling in steel beam models.

Course objectives


This advanced course is designed to provide in-depth knowledge of the nonlinearities typical of civil engineering structures, where large displacements and small deformations are usually considered.

We exclude the study of membrane-type elements with shape finding, but cover many of the relevant situations for modeling geometric nonlinearity and, in some cases, include both geometric and material nonlinearity.

Through a series of videos, including theory and 17 practical exercises in SAP2000, the student will be able to understand concepts such as the geometric matrix, p-delta, linear buckling, nonlinear buckling, large displacements, snap-through, ultimate load estimation, initial conditions, critical Euler load, post-buckling behavior and others. 

The course contains references to design rules related to geometric nonlinearities and examples of typical situations such as buildings, isolated frame elements, shell and cable models.

SAP2000 is used in all the exercises, but the covered topics are universally applicable in the context of nonlinear geometric modeling.


Target Audience


This course requires a solid understanding of structural modeling and analysis, but it also requires some level of knowledge about the concept of geometric nonlinearities and where these effects are relevant in structures and when it is necessary to study them.

Any structural engineering student or professional interested in learning more about geometric nonlinearities and their application in SAP2000 is a good candidate to enroll in this course.
