CONNECTIONS BETWEEN STEEL-CONCRETE COMPOSITE COLUMN AND STEEL BEAM

open access: yesMokslas - Lietuvos ateitis, 2022
Composite steel-concrete columns of circular cross-section have high strength and stiffness, which theoretically could help to reduce the cost of construction, but their advantages are still widely unexploited. In comparison with other constructions, composite columns account for a diminutive market share.

Structural Behaviour of Trapezoidal Web Profiled Steel Beam Section using Partial Strength Connection

open access: yesElectronic Journal of Structural Engineering, 2008
Connections are usually designed as pinned which associated with simple construction or rigid which is associated with continuous construction. However, the actual behaviour falls between these two extreme cases.

Shear Reinforcement of Concrete Beams Using Iraqi Bamboo

open access: yesJournal of Studies in Science and Engineering
Steel rebars require significant energy to produce and are prone to corrosion when exposed to ambient air. Therefore, Iraqi bamboo replaces steel stirrups and steel rebars in this research. Five reinforced concrete beams are tested using four-point load

Inelastic Displacement Ratio Approach for Analyzing the Vertical Elasto-plastic Seismic Responses of Steel Beam Bridges

open access: yesTaiyuan Ligong Daxue xuebao, 2021
The inelastic deformation of a steel beam bridge under vertical seismic actions would accumulate in the “downward” side, whereas in the “upward” side, the structure keeps elastic. An un-symmetric hysteretic model was established for the steel beam bridge

Low‐Cost, Large‐Scale Nanoporous Metals by Mechanical Alloying, Oxide Reduction, and Dealloying of Powders

open access: yesAdvanced Engineering Materials, EarlyView.
Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

Innovative Processing of Compacted Waste Aluminum Alloy Powders via Controlled Remelting and Solidification

open access: yesAdvanced Engineering Materials, EarlyView.
This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

The Influence of Key Component Characteristic on the Resistance to Progressive Collapse of Composite Joint With the Concrete-Filled Steel Tubular Column and Steel Beam With Through Bolt-Extended Endplate

open access: yesFrontiers in Materials, 2019
In this study, a finite element (FE) analysis of a composite joint with the concrete-filled steel tubular (CFST) column and steel beam, with a through bolt-extended endplate, was carried out in a progressive collapse. The reasonable constitutive model of

Experimental and Numerical Investigation of the Behavior of Steel Beams Strengthened by Bolted Hybrid FRP Composites

open access: yesBuildings, 2023
The strengthening of steel beams using hybrid fiber-reinforced polymers (HFRPs) has gained enormous attention over the last decades. Few researchers have investigated the effectiveness of the fastening techniques without a bonding agent to overcome the ...

Prediction of Surface Topography Parameters in Direct Laser Interference Patterning of Stainless Steel Using Infrared Monitoring and Convolutional Neural Networks

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents an infrared monitoring approach for direct laser interference patterning (DLIP) combined with a convolutional neural network (CNN). Thermal emission data captured during structuring are used to predict surface topography parameters.

Mechanical Performance Analysis and Profile Optimization of Pre-bent Steel-concrete Composite Straddle Monorail Track Beams

open access: yesChengshi guidao jiaotong yanjiu
[Objective] Most conventional straddle monorail track beams utilize a profile form with 850 mm width. In response to the urban rail transit construction demands of the third and fourth-tier cities in China, relevant enterprises propose a profile form ...
