| Abstract: |
| An effective method called Appended Massless Constraint Element (AMCE) method is presented and proposed, which is adopted to settle the problem, easy but not to be neglected, inherent in the displacement input model for calculating the structural responses under earthquake-induced ground motion. Based on the comprehensive and intensive analysis of the displacement input model in this paper, it points out explicitly that there is the unstability and extreme irrationality of the calculation results while adopting the displacement input model. To solve the problem, the RMCE method is presented. Then, the rationality and accuracy of the proposed method are further verified. Theoretical analysis and numerical results demonstrate that the proposed method is simple, feasible and possesses high accuracy. |
