4. SEISMIC RESPONSE OF PARTIAL-STRENGTH COMPOSITE JOINTS Figure 4.18. Test set-up for the interior joint CJ-INT Figure 4.19.Global instrumentation for the specimen CJ- INT check the reactions at the supports and to measure the deformation and internal stresses of the specimens. By means of LVDT transducers and inclinometers, positioned as illustrated in Figure 4.19, was possible to determine the global deformed configuration. Moreover, in the zone of the joint, LVDT transducers (see 129
4. SEISMIC RESPONSE OF PARTIAL-STRENGTH COMPOSITE JOINTS Figure 4.20) and strain gauges were positioned in order to investigate the transfer mechanisms from the composite beam to the column; in detail the shear deformation of the web panel and the strain distribution in the concrete slab and in the reinforcing bars were well monitored. 130 Ts.sup.sx Tc.sup Tb.sup.sx Tc.inf Tdia.2 Tdia.1 Tb.sup.dx Tb.inf.sx Tb.inf.dx Ts.sup.dx Ts.inf.sx Ts.inf.sx Figure 4.20. LVDT Transducer in the joint 4.8.2 Specimen behaviour and test results The test results of the four specimens are shown as load-deformation relationships. The number of peaks indicates the cycle numbers. The hysteresis diagrams, characterizing the overall behaviour of the specimen and the behaviour of its components, are as follows: • M-φ hysteresis diagram of the overall behaviour of the specimen; • M-θ hysteresis diagram of composite beam connection rotation; • V-γ hysteresis diagram of web panel zone distortion. Interior Complete Joint CJ-INT For this specimen both the monotonic and the cyclic test were performed. In the following Figure 4.21, Figure 4.22 and Figure 4.23 the moment vs. plastic rotation of a beam-column assembly, the moment vs. plastic rotation of the composite beam connection and the shear vs. plastic distortion of the column web panel are shown.
