The base of the stringer usually sits on a concealed base plate anchored into the concrete slab. The DWG should show the recess in the finished floor so the steel appears to emerge seamlessly from the ground. The Header Connection (The Top) single stringer staircase detail dwg

A (also known as a mono stringer ) is a hallmark of modern architectural design, celebrated for its "floating" appearance and minimalist profile . Unlike traditional stairs that use two side supports, this design relies on a single central beam—the "spine"—positioned directly beneath the treads to carry the entire load. Structural Logic and Anatomy The DWG should show the recess in the
central beam, tread connection (welded/bolted/embedded), handrail post attachments, landing support, and foundations.
| Mistake | Consequence | |---------|-------------| | No lateral bracing | Stringer twists under load | | Missing nosing detail | Trip hazard | | Ignoring torsion on stringer | Structural failure (single stringer twists more than double) | | No tolerance on bolt holes | Field installation impossible | | Wrong weld access | Welder cannot reach joint |
