Introduction

This video compares the 3-term and 4-term deflection equations in the Canadian version of the Shearwalls Program using a more complex shear wall model. The analysis examines a 10-meter-long structure with three wall segments, considering load cases at 50% and 100% of shear resistance capacity. Results show that at lower loads, the three-term equation predicts slightly higher deflections than the four-term equation, but at full capacity, both equations produce nearly identical results. This confirms the accuracy of the nonlinear approach in high-load scenarios.

Learning Outcomes

By the end of this lesson, you will be able to:

• Compare the 3-term and 4-term deflection equations used in shear wall analysis within the Canadian version of the Shearwalls Program.
• Analyze the effects of different load scenarios (50% vs. 100% of shear resistance capacity) on deflection calculations.
• Interpret how material distribution and wall segmentation impact shearwall performance in structural models.
• Evaluate the accuracy of nonlinear and linear deflection equations under varying load conditions.
