【Abstract】 Some computer methods used for nonlinear analysis of high-rise buildings, including object-oriented finite element method, DAO database, OpenGL visualization in scientific computing and sparse matrix are discussed in detail. Object-oriented method makes programming and maintenance of finite element analysis easier. DAO database makes the data between preprocessor, analysis and postprocessor unified. OpenGL visualization in scientific computing can show us the analysis results in graphic forms. Sparse matrix uses little resources and analyses FEM faster. An example is given at the end for the nonlinear analysis of a high-rise steel building using these methods.更多还原
