Research On Frame-multi-ribbed Composite Wall Structure Co-operation

Multi-ribbed composite wall is adapted to national reform and building energy efficiency and the wall of the housing industry needs, is a new structural system of building energy efficiency. Multi-ribbed composite wall because of its unique structural features, in the earthquake, the elastic force stage can be equivalent to a shear wall, however, when access to elastoplastic stage, with the peeling rupture of the filled block, stiffness of the structure changes, structure transition from one stable system to another new stability system, cycle of adjustments in order to avoid resonance effects caused by ground motion, protecting the safety of the structure. Ribbed slab structure introduction to multi-storey and high-rise housing construction, is very necessary, at present the theory and application have yielded the present results, however, the multi-ribbed composite wall for the introduction of frame structure, form the frame-multi-ribbed composite wall structure system, the research is still relatively little. In this paper, mainly on the frame-multi-ribbed composite wall structure system frame with the multi-ribbed composite wall were studied to work, with theoretical analysis, practical engineering examples and the ANSYS analysis, the main contents and results of completed studies are as follows:1. Reference to previous research in this area, and learn the principle frame structure work, brief derivation of the f frame-multi-ribbed composite wall structure of the formula to work, without considering the shear stiffness of multi-ribbed composite wall, derived the Structure's displacement under horizontal load, and frame with multi-ribbed composite wall stand the moment and shear.2. By an engineering example, using the formula derived, calculate the bending moment and shear and displacement, at the same time, considering the size of the beam and the thickness of the multi-ribbed composite wall, list 5 combinations, are calculated combinations of these types of seismic response of structures, compared the change in beam frame and thickness of the wall effect on the structural.3. Using ANSYS finite element software engineering example modeling analysis, BEAM4 unit to simulate beam, SHELL63 element simulation of the floor, LINK10 unit modulus ribbed block wall filled with, use APDL language with parametric modeling and analysis, the results of FEM calculation with the simplified engineering case were similar, with a certain degree of credibility...
