“…Extensive testing has also been conducted on diaphragm connections (e.g., flange-to-flange connectors, reinforcing across joints). These include full-scale experiments on isolated precast connectors (Venuti 1970;Pincheira et al 1998;Oliva 2000;Shaikh and Feile 2004;Pang et al 2012;Watkins et al 2014), tests of connected hollow-core panels (Moustafa 1981;Davies et al 1990) including innovative forms (Menegotto et al 1998), and tests of the connection between the floor slab and perimeter framing, or support connection (Mejia-McMaster and Park 1994;Jensen 2006;Fenwick et al 2010;Corney et al 2014b).…”

Seismic-Resistant Precast Concrete Structures: State of the Art

Precast concrete facilitates a construction method using durable and rapidly erectable prefabricated members to create costeffective and high-quality structures. In this method, the connections between the precast members as well as between the members and the foundation require special attention to ensure good seismic performance. Extensive research conducted since the 1980s has led to new precast concrete structural systems, designs, details, and techniques that are particularly suited for use in regions of high seismic hazard. This paper reviews the state of the art of these advances, including code developments and practical applications, related to four different systems: (1) moment frames; (2) structural walls; (3) floor diaphragms; and (4) bridges. It is concluded from this review that the widespread use of precast concrete in seismic regions is feasible today and that the jointed connection innovation introduced through precast research leads to improved seismic performance of building and bridge structures.dividual papers.

“…Experiments were conducted using a variety of subassemblies that do not necessarily conform to the qualification requirements of Section 8 of this Guide. Experimental data have been generated on bent reinforcing bar hairpin connections (Venuti 1970;Kallros 1987;Naito et al 2009), welded plate connections (Pincheira et al 1998;Naito et al 2006;Cao and Naito 2007), angle plate connections (Spencer and Neille 1976), and a number of proprietary connections. Many of these connection test data sets are summarized in (Oliva 2000;Naito and Ren 2008;Cao and Naito 2009;Ren and Naito 2013).…”

“…He also showed that the connector arm's angle of entry into the concrete slab had virtually no effect on the ultimate strength. More recent testing has been conducted by [3][4][5][6]. The majority of these latter tests were proprietary in nature, but helped to significantly further the understanding of the behavior of double-Tee flange connectors, hence they are mentioned here.…”

Prestressed double-Tee beams are used in multi-level parking structures and in some states' bridges. Steel brackets, called in-flange connectors, are embedded in the flanges of the beams and are welded together on-site to facilitate system behavior. To date, placement, i.e. spacing, of these connectors has been based primarily on engineering judgment although some guidelines are available. This paper summarizes the results of seventy (70) monotonic and twentythree (23) reversed-cyclic tests on double-Tee in-flange connectors in an effort to provide comprehensive information on the relative performance of several different available connectors. Test results are reported for six different connectors manufactured by two different companies using seven different test protocols described herein. Each connector was imbedded in a 965x914x102 mm (38x36x4 in) concrete slab designed to be representative of the overhanging portion of the flange of a concrete double-Tee beam. The connectors were also tested using a slow reversed-cyclic displacement control protocol and the ability of each connector to dissipate/absorb energy is also discussed, along with the relationship to serviceability-related concrete damage, i.e. cracking and spalling.
