From page 1...
... A survey questionnaire was developed to involve bridge owners such as the FHWA, state DOTs, domestic and international universities and organizations, contractors, precast producers, and vendors. The ABC connections identified in the literature study and survey are analyzed and categorized by type, such as bar couplers, grouted ducts, pocket, socket, hybrid, or integral connections, and emerging technologies, such as shape memory alloys and elastomeric bearings.
