What every Engineer should know about bolt tensioning

🔩 Dive deep into the world of bolted connections with our comprehensive guide on structural engineering techniques. In this video, we explore the intricacies of bolted connections used in various structural applications, emphasizing their installation ease and versatility. We'll cover critical aspects such as:
Bolt Failure Analysis: Understand how bolts can fail due to shearing and learn the essential calculations to determine their shearing strength.
Pretensioned Bolts: Discover how pretension affects the stresses in both the connecting surfaces and the bolts themselves, especially under increased loads.
Connection Types: Get insights into slip critical and bearing type connections, and how to accurately evaluate their strength.
Bolt Material and Strength: Delve into the differences between common and high-strength bolts, including A490 and A325 types, and their implications in structural design.
Calculation Methods: Learn the precise methods to calculate the nominal shear strength of bolts, factoring in material type, length, and whether threads are in the shear plane.
Installation Techniques: Explore four authorized procedures for high-strength bolt installation, including the turn-of-the-nut method, calibrated wrench tightening, twist-off-type bolts, and direct tension indicators.
Practical Applications: Understand the scenarios where snug tight and pretensioned bolts are required, and the distinction between slip-critical and bearing-type connections.
📘 We also delve into AISC specifications, discussing how these standards apply to various bolt types and connection scenarios. Our detailed explanation includes the use of manual tables for shear and tensile strength, slip capacity, and bearing strength calculations.
💡 Whether you're a practicing civil engineer, a structural engineering student, or just passionate about structural engineering principles, this video offers valuable insights and practical knowledge to enhance your understanding of bolted connections in steel structures.

@@FrameMindsEngineering being an engineer I am often getting confusion on taking which loads to be considered design for connections. For example if we do model and run calcs where we willget lot of values in the result table from the software in which what value we have to take for design the particular connection. Example base plate, for beam to column connection, etc.,
