Experimental Investigation of Beam-Through Steel Frames with Self-Centering Modular Panels
The beam-through steel frame with self-centering modular panels (BTSF-SCMPs) is a new seismic load–resisting system that combines the ease of assembly of the beam-through main frame with the lateral stiffness and recentering capabilities of SCMPs. The SCMP is designed as a posttensioned steel moment-resisting frame, and in this study, three types of SCMPs with slightly different configurations were fabricated and tested. Columns of the main frame are floor-by-floor connected to the through beam, whereas the prefabricated SCMPs are installed to the prespecified bays of the main frame. Tension-only bracings installed to the main frame or SCMP are intended to serve as replaceable fuse elements. A series of experimental tests were conducted to investigate the cyclic loading behavior of the BTSF-SCMPs with three different types of SCMPs. The experimental results show that the BTSF-SCMP is capable of recentering upon unloading while retaining moderate energy dissipation capacity provided by the tension-only bracings. Also, because of the SCMP, after severe cyclic loading, the BTSF-SCMP system with newly replaced bracings and reused main frame exhibits almost identical stiffness, strength, and recentering ability as that of the original system.
