Complete Guide to Analyzing and Designing Pin Connections in Engineering

In this in-depth video, we delve into the analysis and design of pin connections, a crucial element in civil and mechanical engineering. Pin connections, also known as pin plates or lugs, are widely used as 2D simple supports. This tutorial covers the essential components, including the central steel rod (pin), lugs with circular holes, and retainer elements. We discuss the various failure modes for plates and pins, such as tension failure, plate splitting, shearing, bending, and dishing.
The video further explores the Eurocode 3-1-8 guidelines for designing pin plates, focusing on tension loads along the symmetry axis. We explain the geometry specifications, material properties, and safety factors required for design. Additionally, we provide a detailed analysis of the bearing resistance and maximum contact stress considerations.
Key concepts such as the ultimate tensile strength (fup), yield strength (fyp), pin diameter (D), and cross-sectional area (A) are thoroughly examined. We also highlight the importance of accounting for hole clearance and its impact on overall strength.
By the end of this video, viewers will gain a comprehensive understanding of the structural behavior of pin connections and the critical factors to consider during design. Whether you're an engineering student or a professional, this guide will enhance your knowledge and skills in designing safe and efficient pin-connected structures.

I have a quick question:
Where do all the formulas (tension failure, splitting, shear failure, dishing) from 5:56 onwards come from? I can't find them in Eurocode 3.
Thank you.

Thank you, great question. I do mention in the video that some failure modes are not considered by the Eurocode so I gathered them from literature and added them in the video. Unfortunately the design of pin plates according to Eurocode only is insufficient as it neglects many loading cases that are often encountered in reality.

Thank you for your quick answer.
Do you remember which literature you took these from?
