Abstract
Corrosion attacks steel buildings mainly when the connections wait for welding on site. To investigate the effects, a series of experimental and analytical studies have been carried out. This paper summarizes the main results of the experimental studies. The steel welds with and without rust on the welding surfaces were tested and compared in details. The strength of the weld was found to decrease 5% on average. That’s because the rust raised the level of weld porosity. The results obtained above will be considered together with the effect of workmanship in the companion paper, as to assess the seismic reliability for existing buildings with steel moment frames.
