Lesson 1: Introduction to Shearwalls
Lesson 4: Shearwall Design: Capacity vs. Deflection Based Force Distribution
Résumé du cours

Capacité en fonction de la répartition des forces basée sur la déflexion

Introduction

This lesson explains two methods for distributing shear forces in Shearwalls: capacity-based and deflection-based distribution. Capacity-based distribution is a simpler approximation that assigns forces based on segment length, while deflection-based distribution iteratively adjusts forces to ensure equal deflection across all segments. Although deflection-based distribution is considered more accurate, it can sometimes result in design failures that do not appear in capacity-based calculations. The video demonstrates these methods using Shearwalls Program, emphasizing that engineers must use their judgment to interpret results and determine necessary design modifications.
