Influencing factor on cooperative work of multi-ribbed composite wall plate

Two different models of multi-ribbed composite wall plate were set up for the case of vertical and horizontal load in order to perform the evaluation of monotonic loading.The influence of masonry unit on the kinetic performance of cooperative work of main factors of multi-ribbed composite wall and its deformation was discussed.The computation showed that stress,strain and deformation in the multi-ribbed composite wall were very different in identical experimental conditions.Under external loads,the framed box of IFH-11 sample mainly undertook the majority of external load and the building bore block almost nothing.The box and block of IFH-12 sample as a whole shared the external load.So its stress diagram was consistent with the model of frame tie with multi-ribbed composite wall plate and oblique compressive rod.IFH-11 deformed under external force and the box and block was separated.In sample IFH-12,the box and block bound together as a compact structure with a fine performance to untake force and deformation.
