Area loss of severely weakened rebar cross sections is a crucial variable in assessment of structural deterioration for corroded concrete structures, which is hard to be measured or estimated precisely in conventional methods. In this paper, rebar samples were taken from naturally corroded RC slabs. ...
And the time- dependent mathematical models for mean value and standard deviation of sectional area of a corroding rebar are solved using regression theory. 钢筋锈蚀导致的钢筋截面积损失是混凝土桥梁服役期抗力退化的重要因素。 更多例句>> 3) sectional area 截面面积 1. During the forward filling pro...
= 25 GPa; yield strength of steel Oys = 414 MPa; and modulus of elasticity of steel Es = 200 GPa Canadian rebar sizes (CAN/CSA-G30.18-M92) Mass (kg/m) Nominal Diameter (mm) Cross-Sectional Area (mm) Bar Size 10M 15M 20M 25M 30M 35M...
For example, the axial stiffness of a cross-section with area A, which is composed of a material with elastic modulus E is EA, can be interpreted as the resistance of this cross-section to axial strains. This cross-sectional stiffness combines with complete member geometry and dimensions to ...
In this section, the sectional analysis for arbitrary shape sections, which may consist of four types of components, namely as unconfined and confined concrete, rebar, structural steel and openings, is discussed. An arbitrarily shaped cross section with arbitrary arrangement of reinforcing bars and st...
Therefore, through this cross-sectional study, we aim to comprehend the prevalence of menopausal symptoms among women undergoing physical examinations, along with their attitudes towards menopausal hormone therapy, so as to inform the reduction of the prevalence of menopausal symptoms and improve acceptanc...

Area loss of corroded rebar cross sections is a crucial variable that is difficult to measure. In this paper, virtual models of corroded bars were built using 3D laser scanning technology; and, 693 severely corroded sections were screened to explore a practical way for the area loss ...
The laboratory tests suggest that corrosion duration and rebar cross-sectional area size had a significant impact on the strength and ductility degradation of the specimens. The tensile mechanical properties before and after corrosion indicated progressive variation and drastic drop in their values. The ...
Ii = second moment of area of the i-th element; γi = gamma coefficient of the i-th element; Ai = cross-sectional area of the i-th element; ai = distance between the geometric centre of the i-th element and the centre of the composite section; si = spacing of fasteners; Ki = ...
