Research On Seismic Behavior Of Eco-composite United Limb Wall And Analyse Bearing Capacity Of Resisting Shear

Eco-composite wall structure of filling plant fiber raw soil within the block is a new type of structural system, which is ecological, green, environmental protection and energy saving. As the result of technology improvement of multi-ribbed slab structure previous studied, the new structure not only keeps the good seismic performance of multi-ribbed slab structure, but also embodies such advantages as local conditions and energy conservation of the immature soil material, therefore, the safety, suitability and economy of structures are well combined. As the use of functional and structural requirements of Construction in the building structure, transverse wall of Eco-composite wall structure is usually in the form of united limb wall. In the paper the united limb Eco-composite wall would be researched and by the experiment, nonlinear FEM calculation, theory analysis, the stress mechanism, failure mode, seismic behavior, and ultimate bearing capacity of the wall have been detailed study. The main research contents and achievements are summarized as follows:(1) By the pseudo-static test of the United limb Eco-composite wall, the stress feature, failure pattern, bearing capacity, ductility, energy dissipation and deformation of the wall is analyzed.(2) The nonlinear FEM model is established for the United limb Eco-composite wall, and the analysis results of the FEM and the experimental researches are contrast verification. By using the FEM model, the stress and deformation characteristics of the wall is analyzed in lateral load.(3) By the analysis of experiment and FEM models, the factors which influence the oblique section bearing capacity are researched. According to the numerical simulation results, finally the equation of oblique section ultimate bearing capacity of the United limb Eco-composite wall are put forward.
