Abstract
The Center for Advanced Technology for Large Structural Systems at Lehigh University in U.S.A. has developed a new and innovative series of beam-to-column connections that can be adapted to automated erection processes. The connections developed and tested include a simple shear connection, an all steel moment connection and a semi-rigid composite connection. All of these connection schemes incorporate the use of a self-aligning, self-guiding connector called the ATLSS Connector. The connector was recently used and proven successful in a field demonstration. ATLSS together with the National Instituteof Standards and Technology has been developing a multi-degree of freedom crane to allow these connection systems to be constructed by a hilly automated process.
