Nonlinear Analysis on Stainless Steel Reinforced Concrete Columns under Low-Cyclic Load

Abstract

In order to study the elastic-plastic mechanics properties of the stainless steel reinforced concrete columns under low-cyclic load, the engineering open-source earthquake simulation system OpenSees is used to carry out the numerical simulation. The comparison between the computed results and the pseudo-static test results shows that the OpenSees may stimulate the mechanical properties of the stainless steel reinforced concrete columns by using the fiber element model, both of the skeleton curves and hysteretic curves are well agreement with the tests results.

Experimental Study on SSRC under Eccentric Compression

“…It mainly focuses on two aspects: one is to study its corrosion law in simulated concrete pore fluid and the other is to study its corrosion law in mortar or concrete environment, which is usually compared with carbon steel bars in the same situation by monitoring the corrosion rate. In 2006, Guoxue et al preliminarily discussed the mechanical properties of SSRC beams, slates, and columns [7][8][9][10][11]. In 2007, Yongsheng et al studied and analyzed the influence of the use of stainless steel bars on deflection, crack width, and ultimate bearing capacity of concrete beams and verified that the SSRC beams can meet the requirements of the maximum deflection and maximum crack width limits specified in the design of ordinary reinforced concrete structures [12].…”
