| Abstract: | A considered shear deformation affect,exactitude multi-segment bar member's stiffness matrix was deduced by structural mechanics principle.And then,exactitude multi-segment bar member and simplified pile model were adopted to simulate a seven-story R/C frame supported by some isolated piles.Inputting El-Centro earthquake acceleration records,its seismic responses were computed by time history analysis method.Precision and necessary of the exactitude multi-segment bar member were demonstrated by comparisons of seismic response of three different type element models.11figs.,13refs. |
| Keywords: | seismic response time-history analysis R/C frame exactitude multi-segment bar member simplified pile mode |
