Evaluating the Effect of Earthquake Vertical Component on Large Bay Steel Gabled Frame Located on Flexible Substrate using IDA

Because Steel Gabled Frame, SGF, is essentially a lightweight, in most cases, in addition to the horizontal earthquake component, their vertical component is also ignored. That's while with an increase of SGF bay, structural mass increases significantly and as a Result, vertical motion can prod...
