Will Your Staircase Hold Up? Find out how to design the optimal staircase!

Dive deep into the intricacies of steel staircase design in this comprehensive tutorial! Discover how to analyze the internal forces of staircase stringers and learn the most effective methods for determining boundary conditions. This video is essential for structural engineers, architects, and anyone involved in staircase design and construction.
We'll start by revisiting various types of stringers and their specific design considerations, including the selection of treads for optimal strength and serviceability. We'll discuss the loads that typically act on staircases and how they influence design decisions.
Key topics covered include:
Calculating dead loads for sloping stringer beams and understanding the importance of additional length in sloped members.
Detailed explanation of the sloping beam method and horizontal plane method for determining shear and flexural strength.
Practical examples that illustrate how to calculate gravity loads, shear force, axial compressive strength, and flexural strength using both methods.
Discussion on vertical deflections, how they are affected by the sloping member length, and the methods for calculating accurate deflections to meet serviceability criteria.
Overview of appropriate boundary conditions for different staircase configurations and how to model beams based on support conditions.
By the end of this video, you'll have a clear understanding of how to handle the complexities of designing steel staircases, ensuring that your structures are both strong and compliant with current engineering standards.

At 3:05 for horizontal calculations, why divide 14.2 ft by 12 ft? Aren't we supposed to SW with 12 ft only?

[@FrameMindsEngineering]

The self weight should account for the total length of the stringer but applied along the projected length in the horizontal plane method. Otherwise we would be underestimating the weight of the stringer. Thank you for watching
