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......
Artificial Neural Networks (ANN) Based Compressive Strength Prediction of AFRP Strengthened Steel Tube
International Journal of Steel Structures - Tập 20 - Trang 156-174 - 2019
The use of FRP composites as external confinement has recently become a very important system to consider when reinforcing concrete and steel structures. Many constitutive models have been proposed to design such structures. However, the emergence of artificial neural network offers a better alternative with a strong prediction capability. In this research, an artificial neural network (ANN) based......
Strength and behavior of a vertically pre-tensioned composite rigid frame bridge
International Journal of Steel Structures - Tập 13 - Trang 367-378 - 2013
In this study, a new type of composite rigid frame bridge is developed, and its feasibility was validated through a full-scale test. The core technology of the proposed bridge entails the introduction of prestressing force to steel girders by applying vertical prestressing to readily embedded high-strength steel bars at the pier wall. The proposed prestressed rigid frame bridge was designed to red......
Investigating Approximate Methods to Predict Residual Interstory Drift Ratio Demands in Steel Eccentrically Braced Frames
International Journal of Steel Structures - Tập 22 - Trang 176-191 - 2022
Residual drifts after earthquakes are important for decision-making about repairing or rebuilding a structure. There are some approximate methods that predict the residual drift demands of structures after earthquakes. Most of the approximate methods have been proposed for structures with moment resisting systems. Recent studies have shown that eccentrically braced frames (EBFs) can have considera......
Collapse mechanisms of single curvature tensegrity systems
International Journal of Steel Structures - Tập 17 - Trang 1115-1129 - 2017
Tensegrity systems are composed of any given set of cables connected to a set of struts in which cables connectivity must be able to stabilize the configuration. In the present study, the collapse mechanisms of single curvature tensegrity systems was investigated by carrying out nonlinear collapse analyses using finite element method. Having verified the finite element modeling with the experiment......
An Experimental Study of an SMA-Based Self-Centering Damper
International Journal of Steel Structures - Tập 22 - Trang 610-621 - 2022
The self-centering energy dissipation devices can reduce or avoid the residual inter-storey drifts of structures. This study aims a shape memory alloy (SMA) -based self-centering damper that employs the pre-tensioned SMA wires and pre-compressed springs as energy dissipating group and re-centering group, respectively. Compared with the conventional self-centering dampers which mainly use SMA wires......
Shear Capacity Analysis of Welded Steel I-Girders with Corrugated Webs based on First Yield
International Journal of Steel Structures - Tập 21 - Trang 1053-1062 - 2021
Steel I beams or girders with sinusoidal corrugated profile webs have become popular in the recent development of the steel structural designs, since corrugated-web beams (CWBs) can provide better performance in terms of less deformation and more stability against buckling failure. It is verified in previous research that CWBs can be considered as an alternative to replace normal beams in the stru......
Comparison of bolted end plate and T-stub connections sensitivity to bolt diameter on cyclic behavior
International Journal of Steel Structures - Tập 14 Số 3 - Trang 633-647 - 2014
Seismic retrofit of structures using steel honeycomb dampers
International Journal of Steel Structures - Tập 17 - Trang 215-229 - 2017
The purpose of this paper is to investigate the seismic performance of a honeycomb shaped steel hysteretic damper applied to seismic retrofit or strengthening of a structure. The formulas for the initial stiffness and yield strength of a damper unit were derived based on the cell wall bending model, and the results were compared with those obtained from finite element analysis. Bilinear model of t......
