ULTIMATE BEARING CAPACITY OF MULTI-STOREY STEEL MOMENT FRAME COMBINED WITH LEANING COLUMNS AND HINGED BEAMS
A new structure system witch is multi-storey steel moment frame combined with leaning columns and hinged beams (MFCLC) is put forward in this paper. To research the behavior of this structure system under lateral loads two analytical six-storey steel buildings are designed, one is un-braced steel moment frame, and another is MFCLC. Three-dimension finite element method is used to analysis the two structural models. Ultimate bearing capacities of the two models subjected to three different distribution types lateral loads are studied and compared. The results showed that the new system has similar or even better performance than the pure steel moment frames in the case which not increasing the volume of the steel. In addition, as a result of reducing a large number of steel beam-column rigid connections, the MFCLC can reduce the configuration volume of the steel in total beam-column connections. Steel frames with more flexible beam-to-column connections have also many economical and construction advantages over rigid frames. Thus this MFCLC structure system is recommended to use in seismic and non-seismic regions.
