Single-storey industrial steel frames with cranes are considered as being vertically irregular in structural configuration and load distribution under strong earthquake excitations. In this paper, various frames with their
spans of 20, 26, 32 and 38 m and locations built in Hanoi and Son La regions were designed to resist dead, roof
live, crane and wind loads. The equivalent horizontal and vertical static earthquake loads applied on the frames
were determined. Next, by using linear elastic analyses of structures, the effects of vertical seismic actions on
the responses of the frames were evaluated in terms of the ratios K1 and K2 at the bottom and top of the columns
corresponding...
