“…Belleri et al (2017) have proposed a recentering dissipative device based on rotary friction, in order to introduce energy dissipation in hinged beam-column connections. Also Martinelli and Mulas (2010) have proposed the insertion of devices that dissipate energy through rotary friction but with no recentering capacity. Alternative solutions could be based on dampers, as suggested by Marinini et al (2011).…”

The key element characterizing the seismic vulnerability of existing prefabricated RC structures, not designed for earthquake actions, are friction-based connections between structural members; mainly those between beams and columns and beams and roofing beams. The paper discusses the effectiveness of dissipative connectors made of carbon wrapped steel tubes. In particular, it presents the results of Incremental Dynamic Analyses on portal frames, aimed at evaluating behavior factor values to be used in design. A simplified formula for estimating the behavior factor is also proposed. Results of nonlinear IDAs suggest that the introduction of these dissipative devices in friction-based beam-column joints provides an effective connection between structural members and, in addition, reduces the forces transmitted to columns, improving the seismic behavior of the entire structure.

Single-storey precast frames with pinned beam-column connections are widely used in Turkey. This type of precast structures had suffered extensive damages during the recent major earthquakes (Ceyhan (1998), Kocaeli (1999), Duzce (1999). The damages had been generally concentrated on the pinned connections as failure of dowels or at the column bases as large plastic deformations.A special lead extrusion damper (LED) has been developed in an ongoing PhD study in Istanbul Technical University. The damper is going to be installed into the pinned connection regions of the single storey precast frames.Nearly half scaled specimens representing existing features of precast frames are planned to be tested on the shake table. Prior the experimental work, an extensive blind prediction study has been carried out through the nonlinear dynamic time history analyses of the numerical models which are representing the specimens with and without damper. The numerical models are generated with Seismostruct. The comparison of the structural behaviors between the bare frame and the frame with LED has been discussed. Although the relative drifts of the precast frame has been significantly reduced, the observed base shear demand moderately increased by the installation of the LED.

“…Innovative details for the connections of precast concrete elements have been developed in the last two decades [1][2][3][6][7][8]. Korkmaz and Tankut [1] developed a precast concrete beamto-beam connection with welded plates and concluded that the improved connection detail can be suitably used in seismic constructions.…”

“…On the other hand, Ha and Kim [6] pointed out that half precast concrete beams with a high-ductility connection detail would be practically useful for moment resisting frames as these beams do not demand high transport costs and provide easier towing and handling due to their lighter weight. However, a very few [7,8] investigations on the high-ductile connection detail in half precast concrete beams are available in literature. Even more rare are tests on the flexural behavior of half precast concrete beams with a ductile connection.…”
