Research On The Mechanism Of Frame And Block In Energy-Saving Block & Invisible Multi-Ribbed Frame Composite Walls Under Vertical Load

Energy-saving block & invisible multi-ribbed frame structure is a new structural system, which based on the original structure of small-size concrete hollow block structure and reinforced masonry structure. Its advantage is convenient construction, simple, light energy, green and meets the present establishment of a resorce-saving and environment-friendly society development concept.The study of the interaction mechanism of the frame and block is mainly on the experiment and the theoretical analysis. The research has designed a total number of 9 groups specimens which contain 3 groups under axial load and 6 groups under eccentric load. To compare with the pre-filled test results of the composite wall with energy-saving block, this study use the same size and reinforcement specimens.Analysis the failure process, deformation performance and load-bearing performance, then compare with the results of the wall with the energy-saving block. Finally the paper gets its own characteristics calculation method for the design of the wall under and make a foundation of the design.The study shows that: the block plays a supporting role, the distribution between the two parts relates to the size of the frame, the properties of material and so on. The bearing lode of the wall with the block is better than the frame from 18.7% to 10%. Usually the ribbed beam is under certain force but is very little, and the steel does not yield.
