The Elastic-Static Analysis Of Frame-Supported Shear Wall Structure

Recently, the modern high-rise building is developed in the comprehensive direction with complicated figures and various functions, and the high-rise building with transfer floor is increasingly applied in recent years. The girder transfer floor is widely used in design of high-rise buildings with the characteristics of clear-edge, clear-channel, simple structure and so on. Among the girder transfer floor, transfer beam with shear wall on it, as Frame-supported Shear Wall Structure is the most familiar form.In this paper, stress analysis of framed shear wall with full span wall,framed shear wall with unfull span wall and framed shear wall with double-pier wall or three-pier wall under vertical uniform loads and horizontal uniform loads was studied by applying the large general software ANSYS. It also summarize the stress distribution rules of shear wall and transfer beam. Main conclusions as below:1,Under the vertical uniform loads, the influence on the pier stress of framed shear wall with full span wall induced by transfer beam is in the range of span height , which is in the range of half- storey height of framed shear wall with unfull span wall and storey height of framed shear wall with double-pier wall or three-pier wall.2,Under the vertical uniform loads, large horizontal stress,vertical stresses and shear stresses exist on the bottom of shear wall ,which should be taken seriously when designing.3,Under the vertical uniform loads, there is axial tension in different forms of frame-supported beams at different degree, which is most obvious in the framed shear wall with full span wall .As the length of shear wall become shorter, the axial tension in beam gradually decreases.4,Under the vertical horizontal loads, one side close to outside force is subjected to tension, and the other side bear pressure on the bottom of the limb of shear wall.5,Under the vertical horizontal loads, the stress distribution rules of frame-supported beam of framed shear wall with full span walk the girder segment under the shear wall of framed shear wall with unfull span wall and the opening of framed shear wall with double-pier wall or three-pier wall shows similarities with that of frame beam. The stress in beam is very complex on other position especially joint region.The paper also discusses how to design the frame-supported beam when the shear wall limb has different length.
