Hybrid Moment-Resisting Steel Frames

Engineering Journal, 2011
A new type of moment-resisting steel frame, called a hybrid moment-resisting frame, is described. Unlike a typical moment frame, where all member sizes and connection details fit a specific set of rules (e.g. for a special moment frame), the hybrid frame contains members and connections with a variety of detailing rules, including those typically ...

Moment Redistribution Caused by Beam Fracture in Steel Moment Frames

Journal of Structural Engineering, 2000
This paper presents an analytical study on static moment redistribution and resultant reduction of lateral resistance caused by sudden beam fractures in steel moment frames. A numerical example is presented for a simple multispan frame, and the step-by-step processes of beam fractures, moment redistribution, and loss in resistance under statically ...

Amplified Seismic Loads in Steel Moment Frames

Applied Mechanics and Materials, 2016
This study focuses on exploring the seismic axial loads for columns in steel moment resisting frames (SMRFs) under strong ground motions. For this purpose, the increases in axial loads are investigated at the maximum lateral load level and the corresponding lateral displacement.

SEISMIC ENERGY DEMAND IN STEEL MOMENT FRAMES

Journal of Earthquake Engineering, 1999
The present paper investigates the seismic energy demand in steel moment-resisting frames. The frames, with 3, 6 and 10 storeys, and 4 and 8 spans, are designed according to current seismic code provisions. The energy response (energy quantities and their distributions) in the frames subjected to an ensemble of six earthquake ground motions recorded on

FATIGUE ANALYSIS OF MOMENT RESISTING STEEL FRAMES

Journal of Earthquake Engineering, 2003
A procedure for the fatigue assessment of steel building structures subjected to earthquakes is presented. The procedure constitutes an extension of the present, high-cycle, fatigue assessment to cases of low-cycle fatigue. It may serve as a basis for the introduction of a fatigue limit state in the earthquake design of steel structures. It may be also

Prequalification of Steel Moment‐Frame Connection Performance

Earthquake Spectra, 2003
Welded‐flange/bolted‐web connections were damaged during the Northridge earthquake, and the SAC Steel Project was funded by the Federal Emergency Management Agency to find solutions to the problems caused by this damage. The Connection Performance Technical Advisory Panel was one of several groups completing the project research, and this group ...

Seismic Performance Evaluation for Steel Moment Frames

Journal of Structural Engineering, 2002
A performance prediction and evaluation procedure based on nonlinear dynamics and reliability theory is presented. It features full integration over the three key stochastic models: ground motion hazard curve, nonlinear dynamic displacement demand, and displacement capacity.
