结构抗震的形式控制设计

STRUCTURAL ASEISMIC DESIGN BASED ON FORM CONTROL

理论和实践均表明 ,结构形式对结构的抗震性能存在影响 ,因此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、尺寸的控制设计 ,建立了形式控制抗震设计的数学模型和性能指标 ,算例结果验证了形式控制抗震设计方法的合理性与可行性。

According to different dynamic responses of different structures during earthquake,an organic aseismic design concept in which structure is regarded as both using body and aseismic body is put forward.Mathematical model and aseismic function are established.By using the concept,topo?shape?size and material of structure will be controlled.The computation results for column?arch ring and arch dam in aseismic controllable design prove the model to be reasonable and feasible.
