Most of the time, our building beams are slender enough that shear deformation is an afterthought. We worry about flexural stiffness, slap on a deflection limit, and move on. But as soon as you start working with deep transfer girders, perimeter spandrels, or short plate girders, ignoring shear deformation can quietly under-predict drift and member demand.

How many times have you been up against a deadline and just idealized a connection as “pinned” or “fixed” to get the analysis to run? For decades, this simplification has been the bedrock of frame analysis, a necessary shortcut when we were armed with little more than slope-deflection and moment distribution. But in today’s world of performance-based design and powerful FEA software, clinging to this binary view isn’t just conservative—it can be inaccurate and uneconomical.

You’ve built a complex model, the render looks fantastic, and the software spits out pages of data. But deep down, there’s a nagging question: can I really trust these numbers?
