2021年4月1日 · The present study numerically investigates and compares the seismic performance of a conventional, seismically designed, steel MRF with full-strength CB connections and an equivalent steel MRF equipped with the innovative CB connections (MRF-CB) experimentally investigated in Latour et al. (2019) [36]. In …

2021年10月1日 · Reduced base shear design strength up to 40% for MRFs with dampers for equivalent seismic performance of SMRF structures. This paper presents a simplified design procedure (SDP) for performance-based design of low-rise new steel MRF buildings with nonlinear viscous dampers.

2016年11月1日 · An innovative steel moment resisting frame (MRF) structure composed of high strength steel (HSS) members as the main frame (MF) and energy dissipation bays (EDBs) with reduced beam section (RBS) beams of mild carbon steel was tested. Theoretical analyses are also performed and the favorable seismic performance of the system is clarified.

2024年8月21日 · This paper demonstrates the enhanced resilience performance of steel structures with viscoelastic friction dampers (VEFDs) based on numerical simulations of building responses.

4-story building with perimeter steel special moment frames (SMFs)! Design location Bulk Center Los Angeles, CA! Design provisions: ASCE 7-10, AISC 2010!

Analytical and large-scale experimental studies on steel MRF building structures with nonlinear viscous dampers were conducted. The primary objectives of this research are to investigate the seismic response and performance of steel MRF structures with nonlinear viscous dampers and develop a simplified design procedure (SDP) for seismic design ...

2024年6月28日 · This paper investigates a steel moment resisting frame (MRF) with a novel type of self-centering (SC) base isolators, wherein superelastic shape memory alloy (SMA) U-shaped dampers (SMAUDs) work as c...

The yield and ultimate strength of steel increased; Bolting the shear tab to the beam web without supplemental welds became the norm due to economic considerations; The welding process was changed from shielded metal arc welding (SMAW) to self-- shielded flux core metal arc welding (FCAW) during the 1970s 6.

2005年4月1日 · A post-tensioned friction damped connection (PFDC) for earthquake resistant steel moment resisting frames (MRFs) is introduced. The connection includes friction devices on the beam flanges with post-tensioned high strength strands running parallel to the beam.

2000年4月1日 · In this study, a load-balancing tendon fuse+damper (TFD) system has been adopted, where sacrificial yielding fuse-bars are used parallel to ESD devices to initially help stiffen the structure. A total of seven different configurations were tested with various bracing as well as supplemental damping systems.
