Stuctural Behavior Of Superimposed Hollow Plate Shear Wall With Finite Element Analysis

Composite hollow plate shear wall structure is a prefabricated reinforcedconcrete structure，Composite hollow plate shear wall combines the dual advantagesof full-cast wall panels and prefabricated wall panels, which has good integrity,seismic performance, short duration, and save building materials. Prefabricatedreinforced concrete shear wall structure can be achieved from industrial production,which fit the current construction industry development ideas, and it is a researchtrend of shear wall structure in China. The main hollow plate elements of compositehollow plate shear wall structure are prefabricated in the factory, which is under highdegree of mechanization and professional skills, so the quality of components can beeffectively guaranteed. The duration of the production can be effectively shortened inadvance. And the templates can be reused, saving three materials. Hollow-section canbe used with the forces of each material, and the use of different intensity canimprove the safety of components. Herein composite hollow plate shear wall panels isused as a composite hollow plate shear wall structure system, but the current structureof the wall assembly are solid precast wall panels or laminated solid board, hereincomposite hollow plate shear walls using hollow as a new precast fill the researchgaps. The nonlinear theoretical analysis of the mechanical properties is done towardscomposite hollow plate shear wall panels and full-situ reinforced concrete shear walls.The main contents are as follows:1.Composite hollow plate shear wall structure is introduced, a new combinationbetween the walls is put forward.2.The finite element models of composite hollow plate shear walls and full-situreinforced concrete shear walls are established, compression performance,deformation properties and crack distribution pattern of the two walls are analyzed.3.Comparative analysis of the mechanical properties of composite hollow plateshear wall panels and full-situ reinforced concrete shear walls is done, analyzing thesimilarities and differences of the performance between the two walls.4.With the horizontal load progressively being loaded at the same axial force, thedifferences between mechanical performances of the two walls are analyzed. And thecomparative economic analysis is done.Changes in stress and strain of reinforced concrete structures, factors affectingthe operating characteristics of the force in the two walls are studied in the paper, thestructural properties of composite hollow plate shear walls are further explored.
