TLDR
In this article, the effect of neutral salt-spray corrosion damage on the seismic capacity of welded steel connections was investigated experimentally and numerically, and the results indicated that the larger value could be chosen from the beam flange corrosion and the column web corrosion to estimate the remaining ultimate bearing capacity of existing connections.About:

Comparative investigation of the effect of corrosion on the mechanical properties of different parts of thin-walled steel
Zongxing Zhang,Shanhua Xu,Rou Li +2 more
TL;DR: In this article, the effect of corrosion on the cold-formed effect of C-shaped thin-walled steel was investigated by fracture morphology and stress-strain curves, which can be attributed to the corrosion surface and thickness reduction.

Study on the seismic performance of corroded H-shaped steel columns
TL;DR: In this paper, the effect of local corrosion and axial compression ratio on the seismic behavior of corroded H-shaped steel columns was investigated in finite element analysis, and the degradation model of hysteretic energy dissipation and ductility coefficient of the columns were established.
Journal ArticleDOI
Experimental and numerical investigation of corroded steel columns subjected to in-plane compression and bending
TL;DR: In this paper, the effect of corrosion on the bearing capacity of compression-bending steel members, especially the local buckling behaviors, six H-shaped Q345 steel short columns with different corrosion degrees were designed.

Galvanic corrosion induced localized defects and resulting strength reduction of circular steel tubes under axial compression: An experimental study
TL;DR: In this paper, a modified galvanic method was developed to generate predefined corroded defects at targeted locations, and a total of 24 tubes with different slenderness ratios were produced with various localized corrosion defects, and then axially compressed to obtain ultimate strength.

Bond behaviour between CFRP plates and corroded steel plates
TL;DR: In this article, the authors investigated the bond behavior between CFRP plates and corroded steel plates and found that the failure mode of the specimens mainly depended on adhesive thickness rather than corrosion duration, only when the adhesive layer take a critical thickness, the failure modes would be significantly affected by corrosion duration.

Advanced finite element modeling of bolted T-stub connection components
TL;DR: In this paper, the results of a finite element investigation of the behavior of T-stub flanges are presented and compared to experimental data, and two types of models are employed; a three dimensional TStub model consisting of brick and wedge elements and several two dimensional T-Stub flange models consisting of rectangular and triangular elements.
