122546 - A Case Study on the Effects of Geometry and Stress Around Various Pin-Connected Members 

Pin connections are commonly used in various applications revolving around civil and mechanical engineering. It is also an essential component in pipe support including both hangers and restraints, thus, understanding their current requirements is crucial. This paper involves a case study where different geometry of pin-connected members are examined on multiple stress conditions using finite element analysis (FEA) tools. Varied dimensions of pin and hole as well as multiple locations of the hole has been analyzed under various stress conditions. The stress distribution around the hole has been analyzed in this paper. The goal is to compare that stress distribution along the pin connected members, i.e., the hole, the pin, the connecting unit, and study which configuration would be suitable for which particular condition. The analytical data obtained using FEA and the stress distribution calculations has been used to compare and to select one of the most effective configurations. The primary purpose of the paper is to examine and optimize the effectiveness of pin-connected loads while considering their geometric restrictions. This optimization process involves finding the most efficient design for these members to ensure safety and reliability. The paper focuses on dimensional and stress regulations as per the ASME Boiler and Pressure Vessel Code and AISC 360 and takes into account the latest industry standards and guidelines to ensure compliance with current best practices. The paper investigates an analytical way to understand how the allowable stresses are handled in a certain geometric restriction and how the stress ratio is compared with geometric restriction of the pin, the hole and stress distribution around the hole.
