ANALYSIS MODEL FOR STEEL FRAME-RC INFILL SLIT WALL SYSTEM

摘要：

This paper discussed analytic models of frame-slitwall system suggested by JGJ99-98 and pointed out the necessity of considering shear deformation of web of steel beams when determining the section of equivalent cross bracing or shear plate. The models suggested by JGJ99-98 cannot predict the actual shear forces in steel beams,its bending deformation has not be included either. This paper suggested a wallcolumn model,the rigidities of various parts in this model are proposed. A very low axial rigidity is assigned to the wall-columns modeling the slit walls to implement the design philosophy of carrying no vertical loads by slit wall. Comparison between three models is carried out and it is found that three models predict nearly the same lateral stiffness. But the wall-column model can correctly predict the internal forces and deformations of each member in the model,thus implies an improvement over the cross bracing or shear plate models.
