Impact of design parameters and stress-strain diagrams on the ultimate limit state of instability in reinforced concrete columns [PDF]

Revista IBRACON de Estruturas e Materiais
In high-rise buildings, high-strength concrete (HSC) columns are often used to reduce cross-sectional dimensions while supporting high loads. However, this design decision may result in structures that are more susceptible to deformation, raising ...

Stress-Strain Relationship for Concrete Confined by Rectilinear Reinforcement: A Stiffness Degradation Approach

Journal of King Saud University: Engineering Sciences, 1994
Square tied concrete prisms were tested under uniaxial concentric compressive load. Test variables were the tie spacing and diameter (3 levels each). Based on the observed degradation of the prism’s longitudinal stiffness, a simplified analytical stress ...

Construction of limitation diagrams for truss core stiffness and strength parameters

Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2018
A truss-core sandwich panel is a promising load-bearing element of lightweight high-stiffness structures. The use of this element in load-bearing structures makes it necessary to know its mechanical and strength characteristics depending on the structure

New approach for computing damage parameters evolution in plastic damage model for concrete

Case Studies in Construction Materials, 2022
The Damage Plastic Model is one of the most widespread models used to simulate the real behavior of concrete. The high reliability of this model could be attributed to its ability to take into consideration the elastic stiffness degradation induced by ...

Limit conditions on local failure of nuclear containment steels (Notched round-bar tensile tests for base metals and weld joint materials)

Nihon Kikai Gakkai ronbunshu, 2023
Tensile tests were conducted for notched round-bar specimens to acquire the limit conditions of local failure, which is ductile failure after large local deformation for three types of steel, SGV480, SPV490 and SGV410, for nuclear containment structures.

Ellipticity loss analysis for tangent moduli deduced from a large strain elastic–plastic self-consistent model [PDF]

, 2009
In order to investigate the impact of microstructures and deformation mechanisms on the ductility of materials, the criterion first proposed by Rice is applied to elastic–plastic tangent moduli derived from a large strain micromechanical model combined ...

STRESS ANALYSIS IN CYLINDRICAL SPECIMENS MADE FROM 34CrMo4 USING DIC

Acta Metallurgica Slovaca, 2014
The stress analysis using digital image correlation was carried out on cylindrical tensile specimens made from low carbon 34CrMo4 steel. The results obtained by conventional tensile test were compared with the results obtained by digital image ...
