Simple shear connections have been commonly used in steel-frame construction because they are quick to erect and relatively cost effective. The connections are used for shear resistance, but studies have shown that these connections are capable of sustaining measurable rotational demands and axial load. This enables the connection to help resist collapse in the event of a column failure.
The purpose of this research is to evaluate the robustness of single plate "shear tab" connections when subjected to quasi-dynamic loading scenarios. The research outlines the shear tab's capacity, its ability to utilize catenary action as a source of secondary load transfer, and the connection's innate ability to sustain rotational demands and axial forces in both statically and dynamically loaded connections.
Eleven full-scale tests were conducted, consisting of two wide flange beams connected to a wide flange column stub with single plate connections of three-, four-, and five-bolt configurations. Two of the 11 tests used galvanized bolts. The column stub was pulled vertically downward simulating the compromise of a central column in a building. Axial forces and moments in the connection were calculated from measured strains. Beam rotations were calculated from displacement measurements. Applied load was measured by means of a force transducer.
The shear tab connection resists the applied quasi-dynamic load by means of flexural resistance and catenary action, similar to what was seen in prior static tests. Systems that undergo quasi-dynamic loading achieve failure at a lesser rotation than do those subjected to static loading. An analysis of the work done showed that both statically and quasi-dynamically loaded systems dissipate similar amounts of energy.
