Interior brickinfill partitions are usually considered as
nonstructural components, and only their weight is accounted for in
practical structural design. In this study, the brickinfill panels are
simulated by compression struts to clarify their effect on the
progressive collapse potential of an earthquakeresistant RC building.
Threedimensional finite element models are constructed for the RC
building subjected to sudden column loss. Linear static analyses are
conducted to investigate the variation of demandtocapacity ratio
(DCR) of beamend moment and the axial force variation of the beams
adjacent to the removed column. Study results indicate that the
brickinfill effect depends on their location with respect to the
removed column. As they are filled in a structural bay with a shorter
span adjacent to the columnremoved line, more significant reduction
of DCR may be achieved. However, under certain conditions, the
brick infill may increase the axial tension of the twospan beam
bridging the removed column.
