Abstract: As one of the structural systems of industry workshop, main- and sub-gabled frames system shows certain characteristics of spatial and correlative transferring of loads. Based on an actual example, this article mainly introduces the problems to pay attention to in designing projects by analyzing this kind of structure in different loads and boundaries by MIDAS/Gen.
Keywords: main-and sub-gabled frames system; characteristics of spatial and correlative transferring of loads; MIDAS/Gen
