Seismic Study of Buckling Restrained Brace System without Concrete Infill
International Journal of Steel Structures - Tập 18 - Trang 153-162 - 2018
Bracing is the one of the best-known means of seismic retrofitting. Buckling restrained brace (BRB) is a certain type of brace with great efficiency against lateral loading. This paper presents the results of a finite element analysis on a BRB in which casing has no concrete infill. The core segment of this brace is similar to the conventional BRB, but it has a different buckling restraining syste...... hiện toàn bộ
Fatigue life assessment for a composite box girder bridge
International Journal of Steel Structures - Tập 14 - Trang 843-853 - 2015
Two conventional methods, the nominal stress method and the hot spot stress method, are examined for the fatigue assessment of a steel box girder bridge while considering the effect of the modeling options on the estimated fatigue life. Two analytical models, a simplified global analytical model and a refined local finite element analytical model, are developed for the evaluation of the stress ran...... hiện toàn bộ
Experimental Study of the Mechanical Performance of Corrugated Steel Plate-Concrete Composite Structures
International Journal of Steel Structures - Tập 19 - Trang 733-746 - 2018
This paper presents a comparative study on the composite structure of Corrugated Steel Plate (CSP) with normal and rubberized concrete. One CSP-normal-concrete plate and two CSP arch structures composited with different concretes are established. A theoretical section-property deduction is derived, which demonstrated that the flexural rigidity of such composite structure increased notably. Static ...... hiện toàn bộ
Experimental and Analytical Study for Plastic Moment Capacity of Beam–Beam Splice Connection
International Journal of Steel Structures - Tập 19 - Trang 1202-1208 - 2019
In this paper, both experimental and analytical investigations are presented for the evaluation of yield moment capacity of the extended end plate connections under pure flexural loading. Four point loading system is adopted to simulate the pure bending condition. For the experimental study a beam–beam splice connection is made by joining hollow tubular sections (HTS) using bolted end plate connec...... hiện toàn bộ
Effect of Geometric and Material Properties on the Behavior of Axially Loaded Concrete-Filled Stainless Steel Tube Columns
International Journal of Steel Structures - Tập 22 Số 4 - Trang 1215-1235 - 2022
Formulas for Stress Concentration Factors in T&Y Steel Tubular Joints Stiffened with FRP under Bending Moments
International Journal of Steel Structures - Tập 22 - Trang 1408-1432 - 2022
Stress concentration factors (SCF) of steel tubular T/Y-joints strengthened with different types of fiber reinforces polymer (FRP) materials were studied thoroughly under the action of in-plane bending (IPB) and out-of-plane bending (OPB) moments. A comprehensive FE study was carried out through examining different elements for steel substrate and FRP material along with the corresponding contact ...... hiện toàn bộ
Experimental study and numerical analysis on mechanical behavior of T-shape stiffened orthotropic steel-concrete composite bridge decks
International Journal of Steel Structures - Tập 17 - Trang 893-907 - 2017
A new-type of orthotropic steel-concrete composite bridge deck system was developed, by casting the concrete overlay on the top of the orthotropic steel deck ribbed with T-shape steel members. To study its mechanical behavior (in terms of failure mode, load-deflection relationship, concrete crack initiation and propagation, strength, stiffness and so on), two new-type orthotropic steel-concrete co...... hiện toàn bộ
Residual Bearing Capacity of Damaged Large-Diameter Drum-Welded Spherical Joints Post Disaster
International Journal of Steel Structures - Tập 21 Số 1 - Trang 66-84 - 2021
A Numerical Investigation on Restrained High Strength Q460 Steel Beams Including Creep Effect
International Journal of Steel Structures - Tập 18 - Trang 1497-1507 - 2018
Most of previous studies on fire resistance of restrained steel beams neglected creep effect due to lack of suitable creep model. This paper presents a finite element model (FEM) for accessing the fire resistance of restrained high strength Q460 steel beams by taking high temperature Norton creep model of steel into consideration. The validation of the established model is verified by comparing th...... hiện toàn bộ
