51²è¹Ýapp

Welcome to 51²è¹Ýapp's library of historic steel standards!

This collection is available for those who need access to design information from the past for historical purposes, although we do recommend Design Guide 15 (also available in print) as an easier-to-use resource.

51²è¹Ýapp members may download most these documents for free. The downloads (except for immediate past standards, which are free) are available at a nominal cost to non-members. Any documents that are supplements to past standards are free to everyone.

Categories include historic versions of the following:

• Specification for Structural Steel Buildings
• Code of Standard Practice
• Bolt Specifications
• Seismic Provisions
• Prequalified Connections
• Nuclear Specifications
• HSS (Hollow Structural Sections) Specifications
• Single-Angle Specifications
