Robustness Assessment of Steel Moment Resisting Frames [PDF]

The Open Civil Engineering Journal, 2017
Nowadays, many buildings with steel Moment Resisting Frames (MRF) are built in seismic zones when seismic codes are at its early stages of development, and as such, these structures are often designed solely to resist lateral wind loads without providing an overall ductile mechanism. On the other hand, current seismic design criteria based on hierarchy

Seismic Design and Risk Analyses of Safe-to-Fail Steel and RC Frames for Nuclear Facilities

Jurnal Teknik Sipil
In this article, the design and estimate of the collapse risk of safe-to-fail steel and reinforced concrete (RC) frames due to earthquakes were proposed. The frames are part of nuclear facility buildings, and their failures are to follow the safe-to-fail

Evaluation of seismic reliability of steel moment resisting frames rehabilitated by concentric braces with probabilistic models [PDF]

Journal of Structural and Construction Engineering, 2017
Probability of structure failure which has been designed by "deterministic methods" can be more than the one which has been designed in similar situation using probabilistic methods and models considering "uncertainties".

CONTRIBUTION of GRAVITY FRAMES TO SEISMIC PERFORMANCE OF STEEL MOMENT RESISTING FRAMES

Anadolu Üniversitesi Bilim Ve Teknoloji Dergisi - B Teorik Bilimler, 2018
Traditionally, lateral stiffness and strength of the gravity frames in steel buildings are neglected in structural analysis. During the past earthquakes, such as Northridge, USA, 1994 and Kobe, Japan, 1995, unexpected failures were detected at beam-to-column connections of steel moment resisting frames (MRFs).

Beam Rotation Capacity in Steel Dual Systems: Moment Frames and Eccentrically Braced Frames [PDF]

E3S Web of Conferences
Dual Systems are defined in ASCE 7-22 in section 12.2.5.1. They consist of a moment frame combined with a more rigid system, such as a shear wall or a braced frame, and are capable of supporting 25% of the design seismic load.

Seismic Evaluation of Optimal Performance-Based Design of Steel Moment Frames with Metaheuristic Algorithms [PDF]

پژوهش‌های زیرساخت‌های عمرانی, 2022
Optimal use of materials in constructing structures is one of the main goals of any design. Construction of structural systems is costly for their builders, so structures and buildings that are economically justifiable, appropriate, and meet the ...

Superior design solutions of section sizes in steel buildings for different lateral frame systems and column shapes

Japan Architectural Review, 2020
Superior design solutions of 7‐story steel buildings are obtained by the multiple start local search (MSLS) method, minimizing the steel volume for three types of structural systems: a space‐frame system with rectangular hollow structural section (HSS ...

Hysteresis Envelope Model of Double Extended End-Plate Bolted Beam-to-Column Joint

Buildings, 2021
In this study, a hysteresis envelope mathematical model for the double extended end-plate bolted beam-to-column joint is proposed. The aim of a proposed joint model is to provide a more realistic behaviour of steel frames under seismic loading by using ...
