Steel-fiber reinforced concrete is increasingly being used day by day as a structural material. The complete stress–strain curve of the material in compression is needed for the analysis and design of structure
A method is presented to predict the complete stress–strain curve of concrete subjected to triaxial compressive stresses caused by axial load plus lateral pressure due to the confinement action in circular, box and octagonal shaped concrete-filled steel tubes. Available empirical formulas are adopted ...
To design and analyze structures using steel-?ber reinforced concrete for compression, the stress±strain behavior of the material in compression is needed. While the compressive strength is used for the strength calculation of the structural components, the stress±strain curve is needed to evaluate...
The meaning of STRESS-STRAIN CURVE is a chart or curve showing the relation between the load or stress on a structural member or specimen of material and the corresponding strain or deformation.
Brittle materials Brittle materials such as concrete or ceramics do not have a yield point. For these materials the rupture strength and the ultimate strength are the same. Properties The area underneath the stress-strain curve is the toughness of the material- i.e. the energy the material can...
此弹性区域的材料模数( 杨氏模数,弹性模数) 为一常数定值;所谓模数Modulus=(stress)/(strain) 即为应力-应变曲线上的对应斜率,在此弹性区域上可以藉由简单的应变量值与起始弹性模数的乘积,来计算出应力值,可作为产品设计上的参考依据。 图2: 塑胶材料的应力- 应变曲线图...
