Innovative energy dissipation systems (FUSEIS 1-1) — Experimental analysis

Response of Repaired Fuse Beams to Dynamic Testing

“…The initial behaviour of these 2 specimens is analytically reported elsewhere [4], together with another 3 specimens (totally 5), tested simultaneously. The specimens were mounted to the test frame, and were subjected to horizontal displacement (δ), that was recorded in accordance to the corresponding force F. (Figure 1).…”

“…For each tested specimen. The relevant force-displacement diagram according to the analytical model has been produced and is presented in Figure 3(a) both for the 2 repaired specimens and the five initial specimens [4]. The difference between the two lines is obvious and is primarily due to the number of the beams.…”

“…Relevant full scale tests have been performed at the Laboratory of Steel Structures of the National Technical University of Athens in the context of the "MATCH" research program, in addition to the tests that were performed in the previous "FUSEIS" research program [2][3][4].…”

Performance Assessment of Concentrically Braced Frames With Modified Braces Depending on the Applied Beam-Column Joints

“…Thus the main loads of the braced frame columns are primarily axial resulting from the seismic action, and the remaining frame columns carry the gravity loads. A similar design approach may be seen in [14], [15], [16]. The CBF-MB system was designed according to [5] by a multi-modal response spectrum analysis.…”

Behavior of High Strength Steel Fuseis Seismic Resistant Systems

“…In total, eight FUSEIS full scale tests will be performed in the Institute of Steel Structures of the National Technical University of Athens in the context of the "MATCH" research program, in addition to the tests that were performed in the previous "Fuseis" research program [9], [10]. The parameters differentiating the various experimental investigations are the cross sections of the fuses, their materials and the loading protocols applied.…”
