Abstract:According to the problem of structure dynamic response analysis, current using methods and methods in research were discussed. These methods are classified into four categories:explicit differential method, implicit step by step integration method, precise integration method, high precision interpolation method. Theory,accuracy, efficiency and extended research on these four categories methods were explained and discussed. Application of high accuracy numerical method in structure project was expected.
Keywords:structure dynamic response analysis; differential method; step by step integral method; precise integration method; differential quadrature method (DQM)
