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.
