Abstract
Abstract Significant changes in the erection of structural steel for buildings and bridges, especially in steel-to-steel connections, are resulting from major revisions to AISC (American Institute of Steel Construction) Specification for Structural Joints Using ASTM A325 or A490 Bolts. The changes are altering decades-long practices in using these high-strength steel bolts. This article covers the key changes in installation, tensioning, tension calibrating devices and methods, inspections, storage and handling, painting, burr removal, and other factors. This note is of concern to all who use steel bolts or erect structural steel.
