| 中文摘要: |
| 根据不同结构形式在地震中表现出迥异的抗震性能这一客观事实 ,提出了既将结构视为使用主体 ,又将其视为抗震主体的一体化抗震设计概念——对结构的拓扑、形状、尺寸和材料的自控制设计 ;从结构的动力状态控制方程出发 ,建立了自控制抗震设计的数学模型和功能函数 ,并应用于小湾拱坝的体型抗震控制设计中 ,获得了合理可行的控制体型 ,控制体型在应力指标和大坝体积上均得到改善 ,体现了较好的抗震安全性与经济性 |
| 英文摘要: |
| According to different dynamic response of different structure during the earthquake process,an organic anti-seismic design concept, in which structure is regarded as both using body and anti-seismic body, is put forward. From the structural dynamic state controllable equations, a mathematical model and a anti-seismic function are established.By using the concept,the topo?shape?size and material of the structure will be controlled. The computation results of anti-seismic controllable design for Xiaowan arch dam prove the model to be reasonable and feasible. The volume and stress of the self control dam are improved,anti-seismic safety and economy of the self control dam are better in comparison with the virgin dam. |
