Theoretical Research On The Structure With Special Shaped Columns Considering The Effect Of Masonry Stiffness

Structure with special-shaped columns and masonry filled is the familiar frame structure system on the building structure; it is important gist of building design that internal force calculation and analysis of frame structure design. Masonry As a un-structural component of Structure with special-shaped columns and masonry filled, it is aroused common attention of researcher in internal and overseas on the lateral force performance. Therefore there is a necessity to develop special software to design and analyze this kind of structure. In this thesis, several aspects as follows are studied.Based on the experiment data on the model of structure with special-shaped columns and masonry, it is built structure analysis on the Structure with special-shaped columns and masonry. In the model, masonry uses X shape member bar instead of masonry and formats stiffness matrix; frame formats stiffness matrix of structure with special-shaped columns through bar element in 3D space. Therefore, masonry in the structure with special-shaped columns as structural component, it should be considered to the stiffness matrix of structure with special-shaped columns on the internal force calculation and analysis of frame earthquake-resistance design. So it come to appropriate on analysis for the Structure with special-shaped columns and masonry filled.Concrete constitutive relationship and steel reinforcement constitutive relationship on the suggested of Kent and Park are used, and every member bar is divided to five elements. Every element is analyzed with Gauss integral by dividing to five cross sections. Strip method is adopted in the element cross sections division. Increment variable stiffness method is applied to the element loading manner. The program of complete procedure for Structure with special-shaped columns and masonry filled has been developed in the environment of Visual Fortran. Rationality of the model is demonstrated by the experiment data.The object-oriented CAD system for space structure with special-shaped columns and masonry filled (SCCAD) has been developed in the environment of Visual Fortran. Structure with special-shaped columns and masonry filled is analyzed as solid by the program. The behavior of R.C. columns subjected to biaxial eccentric loading is appropriately reflected by the program calculation results. The method of Numerical analysis is adapted to the calculation on the design of Normal cross section and...
