Скачать или смотреть How Accurate Are Design Codes for Shear Stud Capacity? | Dr Jawed Qureshi

In this video, Dr Jawed Qureshi explores the behaviour of shear connectors in composite beams, with a focus on push-out tests, shear stud performance, and design code limitations. Learn how shear strength is affected by slab type, stud spacing, and concrete cone failure.

Dr Qureshi shares findings from his PhD research and industry testing, explaining how design codes apply reduction factors and why real-life beam performance can differ from laboratory results. Whether you're a civil engineering student or a practising structural engineer, this video breaks down complex concepts in an understandable way.
Watch to learn:
• Why double studs may reduce shear per stud
• How profiled sheeting influences slip and failure
• What testing approaches are used and their limitations
• Why relying solely on manufacturer data can be risky
