The tensile strength of steel refers to its ability to withstand axial loads or tension without breaking. Yield strength is the point at which deformation becomes permanent, and ultimate tensile strength is the maximum stress a material can endure before breaking. For example, common structural steel...
There is provided a high tensile steel sheet excellent in crack resistance during gas cutting and toughness during large heat input welding and having tensile strength of 780 MPa, having a predetermined components and satisfying (1) formula in a range of 0.45% to 0.65% and (2) formula in the...
formula for the tensile strength of the steel fiber reinforced concrete is put forward.The results show that tensile strength of the steel fiber reinforced concrete is influenced by the steel fiber volume and the strength grade of concrete and good agreement between the theoretical values and the ...
Calculating results are in agreement with experimental data. The coefficient proposed in this paper has clear geometrical and physical meanings. Furthermore, the formula for calculating the nonuniformity coefficient of steel strain has also been simplified herein. 展开 被引量: 3 年份: 1985 ...
Degradation of bond strength due to corrosion of steel strands is of great importance for serviceability of prestressed concrete structures. An analytical model is proposed to demonstrate the effect of corrosion of steel strand on reduction of bond stren
