Steel Connections -Dr. Seshu Adluri
Introduction
Steel ConnectionsMany configurations are used for force transfer in connections. The configuration depends upon the type of connecting elements, nature and magnitude of the forces (and moments), available equipment, fabrication and erection considerations, cost, etc.
