Abstract: Steel self-centering moment-resisting frames (SC-MRFs) are a class of low-damage seismic-resistant structural systems, which use posttensioned high-strength steel bars to provide self-centering capability and yielding or ...

Abstract: Steel yielding hysteretic devices provide a reliable way to increase the energy dissipation capacity of structures under seismic loading. Steel cylindrical pins with hourglass shape bending parts (called web hourglass shape ...

Abstract: This paper presents ultralow cycle fatigue tests and the calibration of different fracture models for duplex stainless-steel devices of high seismic performance braced frames. Two different geometries of the devices were ...

Abstract: This paper presents the experimental evaluation of an earthquake-resilient rocking damage-free steel column base, previously proposed and numerically investigated by the authors. The column base uses post-tensioned ...

Abstract: Externally prestressed steel–concrete composite (EPSCC) beams in their deformed configuration are characterized by changes in the effective depth of external tendons. However, little information is available on this ...

Abstract: Links in eccentrically braced frames (EBFs) are designed with transverse web stiffeners to achieve the desired seismic performance targets established in current design standards. Prior studies have suggested that stiffener ...

Abstract: An alternative and efficient procedure to estimate the maximum inelastic roof displacement and the maximum inelastic interstory drift ratio along the height of regular multistory steel MRF subjected to pulselike ground ...

Abstract: The maximum inelastic response of bilinear single-degree-of-freedom (SDOF) systems when subjected to ground motions without distinguishable pulses is revisited with dimensional analysis by identifying timescales and length ...
