The Analysis Of The Aseismic Behaviour Of Shear Wall Structure With SRC Supporting Frames And Girder Transfer Floor

The paper is concerned with aseismic behaviour of the shear wall structure with steel reinforced concrete ( SRC ) and reinforced concrete (RC) supporting frames and girder transfer floor under horizontal load of seismic force. The shear wall structure with some supporting frames and girder transfer floor has a structure character of "the above stiffness is bigger than underside" due to its uneven stiffness distribution. By adopting the finite-element analysis program - ANSYS . we calculated and analyzed the anti-seismic behavior influenced by changing the composition of the structures which under the girder transfer floor. We use the two finite element method, which one is separated method and the other is integering method, to simulate the structures. In order to research the dynamic behavior of the structures, subspace method was used to solving self-vibration frequency and mode paticipation factor. Basing on the feature of the structure member, the structure is simplified to a 3-D model consist of space beams and shells , so we can make response spectrum dynamic analysis on the finite-element models . At last nonlinear finite element dynamic analysis was made about the structures .The calculated results reveal the rule of dynamic response about model the and show that the aseismic behaviour and failure mechanism of shear wall structure with SRC supporting frames and SRC girder transfer floor is better than that of RC one.
