A New Step-by-step Integration Method Based ON Uniform Qunitic B-spline Interpolation for Dynamic Response
摘要
Abstract
In order to calculate structural dynamic response , a new step-by-step integration is presented .The step-by-step recursion method is deduced on the basis of uniform quintic B -spline interpolation of nodal displacement , velocity, and acceleration within a local time domain .Two parameters are introduced to meet good stability and accuracy .The proposed method has advantages of self-starting and no middle computational procedure .The numerical results and the comparison with Newmark and Wilson method show this method possesses high calculation accuracy .关键词
