“…Furthermore, other works reported that the formulas of codes GB 50010 and ACI 318 were conservative in predicting the flexural capacity of the stainless steel-reinforced concrete beams [34,[64][65][66]. However, it is not necessarily safe to apply the Eurocode 2 material model directly to the stainless steel-reinforced concrete members, and the proper consideration of the strain hardening characteristics of stainless steel bars in the design process is conducive to improving the flexural capacity and ductility of concrete beams [67,68]. In addition, Zhang et al [64] found that the deflection of stainless steel-reinforced concrete beams calculated by the formula of code American ACI 318 was better than that predicted by the formula of code Chinese GB 50010.…”

The durability of concrete structures can effectively be enhanced by using stainless steel rather than ordinary steel reinforcements under harsh service conditions. Because the basic mechanical properties and stress-strain relationship of stainless steel reinforcements obviously differ from those of ordinary steel reinforcements, the current design codes for reinforced concrete structures are not appropriate for stainless steel-reinforced concrete. On the basis of the research works reported in the past decades, this paper systematically summarizes and analyzes the mechanical properties and corrosion resistance of stainless steel reinforcements, the properties of the bond between stainless steel reinforcements and concrete, the mechanical properties of stainless steel-reinforced concrete members, and the application of stainless steel reinforcements in practical engineering and proposes relevant problems which should be examined further. It is suggested that the design theory of stainless steel-reinforced concrete structures should be further improved to take full advantage of these structures.

“…Instrumental measurements allow to observe the vertical and horizontal deformations of superstructures and supports. Those measurements allow to timely the detect hidden defects that cannot be discovered during the inspection, help explain the appearance of defects found during the inspection, as well as choose the most correct ways to repair and strengthen the structure [9][10].…”

The article presents results of the overpass condition survey, technical survey, static tests and assessment of the structure operational reliability, a doubledecker overpass on Almaty-Kapshagai highway section in Kazakhstan. Technical survey determined the dimensions of the overpass, the camber of reinforced concrete superstructures main beams and checked the values of the overpass roadway actual transverse and longitudinal slopes. The calculation and analytical assessment of the overpass load-bearing structures, for the strength of the bending moment, are performed. Static tests of the overpass split beam superstructure of a length of 33.0m were conducted. Trucks loaded with ballast were accepted as a test load.

“…However, there was an error between the results with or without the bond-slip and the experimental values due to the difference between the RPC constitutive relationship curve and the actual value. The dilatancy angle, eccentricity, the ratio of initial equibiaxial compressive yield stress to initial uniaxial compressive yield stress, the ratio of the second stress invariant on the tensile meridian, and viscosity coefficient were set as 30°, 0.1, 1.16, 0.6667 and 0.0005, respectively [ 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 ]. Thus, the bond-slip constitutive relationship between the section steel and RPC was not accurate.…”

In this study, based on the concrete damaged plasticity (CDP) model in the ABAQUS software, various plastic damage factor calculation methods were introduced to obtain CDP parameters suitable for reactive powder concrete (RPC) materials. Combined with the existing tests for the bending performance of steel-reinforced RPC beams, the CDP parameters of the RPC material were input into ABAQUS to establish a finite element model considering the bond and slip between the steel and RPC for numerical simulation. The load-deflection curve obtained by the simulation was compared with the measured curve in the experiment. The results indicated that on the basis of the experimentally measured RPC material eigenvalue parameters, combined with the appropriate RPC constitutive relationship and the calculation method of the plastic damage factor, the numerical simulation results considering the bond-slip were in good agreement with the experimental results with a deviation of less than 10%. Thus, it is recommended to select a gentle compressive stress-strain curve in the descending section, an approximate strengthening model of the tensile stress-strain curve, and to use the energy loss method and Sidoroff’s energy equivalence principle to calculate the RPC plastic damage parameters.
