Abstract: Multi-ribbed wall plate with lightweight frame structure is a new structural system that the weight is light, the rigidity is big, the anti-seismic capacity and the effect of saving energy are good, the social benefit is high, green and environment protection, which different from structure of ordinary frame and shear wall. Multi-ribbed composite wall is the main components of Multi-ribbed wall plate with lightweight frame structure. In this paper, the calculating model of rigid frame with diagonal strut for Multi-ribbed composite wall was discussed. In order to calculate the Multi-ribbed composite wall conform to the rigid frame diagonal strut model, the entity model and the rigid frame diagonal strut model of Multi-ribbed composite wall were built under the same condition of materials and specimens size to calculate monotonic loading condition, at the same time, the mechanical properties and deformation situation of the Multi-ribbed composite wall at work were analyzed. The diagonal strut width was determined by the Mechanics theory to establish the entity model and the rigid frame diagonal strut model, and comparing the stress and strain of the entity model and the rigid frame diagonal strut model about Multi-ribbed composite wall to prove the rigid frame diagonal strut model Suitable for solve the Multi-ribbed composite wall to provide the theoretical basis.
Keywords: Multi-ribbed composite wall, the entity mode, rigid frame diagonal strut model, non-linear finite element
