Lecture

Nonlinear Analysis of Structures

Description

This lecture covers the topic of Multi-Point Constraints (MPC) in the context of nonlinear analysis of structures. It discusses the application of MPCs in finite element models, including examples like diaphragms in buildings and beam-column joints. The lecture explains different methods to implement MPC equations, such as Master-Slave Elimination, Penalty Function, and Lagrange Multiplier. It also delves into the numerical examples of small frames with 4 DoFs, demonstrating how constraints are enforced using these methods.
