Dynamic Analysis of a Steel Floor System with Dry Slabs Subjected to Vibrations Due to Human Walking
International Journal of Steel Structures - - 2020
One of the contemporary architecture trends is the design of structural elements that cover longer clearances to provide flexibility in the architecture of buildings. The technological and constructive evolutions in civil engineering assure the feasibility of such trends due to the use of structural elements with increased slenderness and reduced weight, such as steel structures that utilize dry s......
Rotational Stiffness Requirements of Closed-Section Stiffeners for Buckling Strength Increment of Stiffened Plates Under Uniaxial Compression
International Journal of Steel Structures - Tập 19 - Trang 1707-1717 - 2019
In these days, closed form solutions to estimate the strength increment in the local buckling strength due to the rotational stiffness of the closed-section ribs have been proposed through theoretical approaches using the energy methods and parametric numerical analysis. In this paper, the correlations between the local buckling strength of longitudinally stiffened plates and the rotational restra......
Finite element investigation of shear capacity of locally corroded end panel of steel plate girder
International Journal of Steel Structures - Tập 13 - Trang 623-633 - 2014
This study discusses the effect of local corrosion damages nearby the bearing region including the bearing stiffener and adjacent web damage on the ultimate shear and post-buckling strength of steel plate girder bridges. A computer package ABAQUS is utilized for the verification and extension of the numerical study. Various corrosion damage cases, specifically the bearing stiffener are studied con......
Random Vibration Analysis of a Vehicle–Bridge Interaction System Subjected to Traveling Seismic Ground Motions Using Pseudo-excitation Method
International Journal of Steel Structures - Tập 22 - Trang 1669-1685 - 2022
For long, multi-span bridges, traveling seismic waves arrive at different bridge support points at different times. To study this difference, random dynamic vibration analysis of a vehicle–bridge interaction system under traveling seismic ground motions was performed in the present paper. A vehicle model with 27 degrees of freedom is used, while three-dimensional Euler beams are used to model the ......
Comparative Analysis of Code-Based Dynamic Column Removal and Impact-Induced Progressive Collapse in Steel Moment-Resisting Frames
International Journal of Steel Structures - Tập 23 - Trang 1576-1586 - 2023
Civil structures are subjected to accidental or intentional impacts, which can lead to an initial failure, and subsequently to a tragic progressive collapse. While progressive collapse studies have seen significant growth, most of the current research focuses on threat-independent approaches, neglecting the explicit consideration of impact effects on the building’s behavior. In this study, we inve......
Composite behavior of steel I-girders connected to inverted-T bent cap
International Journal of Steel Structures - Tập 14 - Trang 711-721 - 2015
This study presents new steel girder bridge system. The main feature of the proposed bridge is the construction of steel I-girders and inverted-T bent caps at the same elevation. Thus, the proposed bridge system eliminates huge bent cap in traditional girder bridge and provides more space under the bridge. In this system, the composite behavior of the joint is the key to ensure structural performa......
Probabilistic assessment of structural seismic performance influenced by the characteristics of hysteretic energy dissipating devices
International Journal of Steel Structures - - 2015
The seismic performance of a structure with hysteretic energy dissipation devices (HEDDs) is significantly influenced by their cyclic structural characteristics. This is due to the fact that the acceleration and displacement responses of the structure mainly depend on the dissipating capacities of HEDDs. Hence, it is important to verify the cyclic characteristics of the HEDDs in designing the stru......
Bearing capacity of non-linear metallic spiders used in point supported glass facades
International Journal of Steel Structures - Tập 12 - Trang 191-204 - 2012
Experimental and numerical investigations on bearing capacity of non-linear metallic spiders used in glass facades were presented. The non-linear metallic materials adopted in this study included two aluminum alloys (ZL105-T1 and ZL111-T6) and one austenitic stainless steel (AISI 302). A total of 21 spider specimens including three types of configurations were tested. Numerical simulation of the t......
A simplified method for free vibration analysis of cable-stayed bridges
International Journal of Steel Structures - Tập 16 - Trang 151-162 - 2016
A simplified method for the accurate prediction of the natural frequencies of cable-stayed bridges is proposed in this paper. In the proposed method artificial neural network (ANN) is applied to derive a simple formula to predict the natural frequencies of cable-stayed bridges based on existing natural frequency data. Unlike in the existing empirical methods, no functional relationship among the v......
Experimental and Numerical Investigation of Steel Beam-to-CFST Column Frame-Thin Steel Plate Shear Walls with Cross Stiffness
International Journal of Steel Structures - Tập 19 - Trang 1895-1910 - 2019
Steel plate shear wall (SPSW) systems have been used increasingly in medium- and high-rise buildings in recent decades. Two major issues in the slender-web SPSW are the buckling of H-section steel column base and significant pinching in hysteretic curves. As a solution, SPSW using concrete-filled steel tubular (CFST) column and cross stiffeners was proposed in this paper. Cyclic tests of two speci......
