Some typical problems in seismic design of transverse steel frames of single-storey single-span industrial buildings
Focusing on transverse steel frames of single-storey single-span industrial buildings,this study discusses the potential plastic hinge location and some related typical problems including the beam-column bending strength ratio,the ultimate strength design of the beam-column connections and beam splicing joints,and the beam width-thickness ratios in seismic design of the frames.It is pointed out that potential plastic hinge regions are generally located at the top section of the columns and the strong column-weak beam requirement on such frames is not necessary,Consequently,the lower between the plastic bending resistances of the beam and column cross-sections with a connection coefficient can be used for the ultimate strength design of the rigid beam-column connections.In addition,the strength requirement on the beam splicing joints and the width-thickness ratio issue of the roof beam are discussed,with corresponding proposals presented.
