Flexural Behavior of Innovative Posttensioned Composite Beams with Corrugated Steel Webs

open access: yesAdvances in Materials Science and Engineering, 2021
Steel-concrete composite beams with corrugated steel webs (CSWs) usually have concrete flanges that are prone to crack under tension, and an innovative posttensioned composite beam (IPCB) with CSWs has been proposed previously to overcome this ...

Meso-scale modelling of 3D woven composite T-joints with weave variations [PDF]

open access: yes, 2019
A meso-scale modelling framework is proposed to simulate the 3D woven fibre architectures and the mechanical performance of the composite T-joints, subjected to quasi-static tensile pull-off loading. The proposed method starts with building the realistic

Application of response surface methodology to stiffened panel optimization [PDF]

open access: yes, 2006
In a multilevel optimization frame, the use of surrogate models to approximate optimization constraints allows great time saving. Among available metamodelling techniques we chose to use Neural Networks to perform regression of static mechanical criteria,

Experimental and numerical investigations of partially encased composite columns under axial load [PDF]

open access: yesJournal of Structural and Construction Engineering, 2019
In current international practice, composite construction is gaining importance in industrial buildings and in particular in high-rise buildings. Partially encased composite (PEC) columns are one of the recent developments in composite column.

Leakage control for a flat flange model with a gap based on sealing liquid viscosity

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2021
Flat flanges are sealed using a gasket, used to prevent leakage between the static surfaces. Gaskets comprise synthetic materials such as rubber, copper alloys, and plastic and they are inserted between two planes to strengthen the sealing performance ...

The Concrete Effective Width of a Composite I Girder with Numerous Contact Points as Shear Connectors

open access: yesApplied Mechanics
Due to the shear strain in the plane of the slab, the parts of the slab remote from the steel beam lag behind the part of the slab located in its proximity. This shear lag effect causes a non-uniform stress distribution across the width of the slab. As a

Influence of flange width and wall parameters on effectiveness of cold-formed steel Sigma-profile in bending behavior [PDF]

open access: yesИнженерно-строительный журнал, 2013
The effectiveness of bending behavior of cold-formed steel profiles is studied. The purpose of the study was to estimate the influence of section parameters - flange width and size of the wall portion, adjacent to the flange – on effectiveness of the ...

The calculation of anchors in steel-concrete overlaps with precast slab [PDF]

open access: yesE3S Web of Conferences, 2019
Reinforced concrete floors and steel beams are widely used in buildings and structures for various purposes. Reinforced concrete overlaps can be cast-in or precast of hollow-core slabs.

Analytical Study on the Effective Flange Width for T-shaped Shear Walls

open access: yesPeriodica Polytechnica Civil Engineering, 2020
This study was organized to derive simplified expressions to estimate the effective flange width for T-shaped shear walls at different loading stages. For that purpose, the variation in the effective flange width was explored by introducing dimensionless effective flange width coefficient.
