INVESTIGATION THE BEHAVIOR AND COMPARISON OF RELIABLE CODES ON CONCRETE-STEEL COMPOSITE COLUMNS [PDF]

open access: yesمجله مدل سازی در مهندسی, 2010
Even though composite columns in buildings and other structures have been used widely more than 50 years and also this procedure is increasing worldwide, likewise very common in practice to either neglect the synergetic contribution of either the steel ...

Post-peak Behaviour of Composite Column Using a Ductile Lightweight Aggregate Concrete

open access: yesInternational Journal of Concrete Structures and Materials, 2021
Oil palm shell (OPS) concrete filled steel tube (CFT) columns are acknowledged to be a new type of sustainable composite column. In this type of column, the conventional coarse aggregate was partially replaced with OPS lightweight aggregate to provide a ...

Experimental and Numerical Study of FRP Encased Composite Concrete Columns [PDF]

open access: yesJournal of Structural and Construction Engineering, 2017
A new type of composite column is presented and assessed through experimental testing and numerical modeling. The objective of this research is to investigate design options for a composite column without the use of ferrous materials.

One dimensional modelling of failure in laminated plates by delamination buckling [PDF]

open access: yes, 1981
When low speed objects impact composite laminated plates delamination may result. Under inplane compression such delaminations may buckle and tend to enlarge the delaminated area which can lead to loss of global plate stability.

Fire resistance of steel beam to square CFST column composite joints using RC slabs: Experiments and numerical studies [PDF]

open access: yes, 2019
In this paper, experimental investigation and numerical simulation of steel beam to square concrete-filled steel tube (CFST) column composite joints that use reinforced concrete (RC) slabs subjected to localized and global fire conditions are presented ...

The XMM-Newton wide-field survey in the COSMOS field. IV: X-ray spectral properties of Active Galactic Nuclei [PDF]

open access: yes, 2006
We present a detailed spectral analysis of point-like X-ray sources in the XMM-COSMOS field. Our sample of 135 sources only includes those that have more than 100 net counts in the 0.3-10 keV energy band and have been identified through optical ...

Axial Compressive Performance of a Composite Concrete-Filled GFRP Tube Square Column

open access: yesApplied Sciences, 2021
A composite concrete-filled glass fiber reinforced polymer (GFRP) tube square column is a new type of composite column, where GFRP is externally wrapped over several GFRP square tubes to form a multicavity GFRP tube, and then concrete is poured inside ...

Column-by-column compositional mapping by Z-contrast imaging

open access: yesUltramicroscopy, 2009
A phenomenological method is developed to determine the composition of materials, with atomic column resolution, by analysis of integrated intensities of aberration-corrected Z-contrast scanning transmission electron microscopy images. The method is exemplified for InAs(x)P(1-x) alloys using epitaxial thin films with calibrated compositions as ...
