ABSTRACT
Experimental research and numerical analysis are carried out on weather-resistant steel beam-to-column connections to investigate their mechanical properties in corrosive environment. Experiments of typical beam-to-column connections under normal condition and total corrosion condition are carried out respectively, and mechanical indexes such as failure mode, bearing capacity, deformation performance, and local plastic development of beam-to-column connections are compared and analyzed. Through collection and statistics of the monotonic tensile test data of weather-resistant steel, a calculation method of the constitutive relationship of weather-resistant steel under corrosion conditions is proposed. Accordingly, the numerical analysis of the weather-resistant steel beam-to-column connections is carried out. The results show that deformation and bearing capacities of weather-resistant steel beam-to-column connections decrease with the accumulation of corrosion-induced mass loss. The bearing capacity loss approximately changes in proportion to the corrosion mass loss (1:1), while deformation capacity loss of specimens (specifically referring to the ultimate displacement and ductility factor) is four times as much as the corrosion mass loss. In addition, the local corrosion of upper flange weld of the weather-resistant steel beam-to-column connection has the most significant effect on the deterioration of the mechanical properties of the connection. As the local corrosion zone is far away from the column, the deterioration effect of local corrosion on the beam upper and bottom flange tends to decrease.
