| Abstract: |
| The computation of earthquake pounding force response spectrum is base on the pounding time history analysis of two adjacent structures.The analysis requires an application of numerical analysis with good stability,high precision and efficiency.The precise integration method,which is a method to convert the two order dynamic equation into Hamiltonian dual variables system by means of element addition and order reduction,provides an accurate solution for the time history problem.Based on this point,the paper introduced the precise integration method to simulate the pounding process of adjacent structures and compute the earthquake pounding force response spectrum.The PIM formulas correspond to structure pounding problems were derived,the structure pounding analysis program and earthquake pounding force response spectra program were coded in environment of Matlab.And furthermore,the parallelization of the pounding force response spectra program was implemented.An example was applied to verify the program.The results indicate that the method adopted by this paper can be effectively applied to simulate structure pounding process as well as compute the earthquake pounding force response spectrum with a high accuracy solution. |
