9403592 Skelton This project develops analytical methods for predicting the dynamic response of civil engineering structures, and new structure design concepts to improve the dynamic response. The upper bounds on the dynamic response for structures with some modeling uncertainties, and with some uncertainties in the static and transient loads will be established. Safe performance for a variety of design goals, including the ability to withstand worst case wind loads and earthquake excitations, in the presence of a specified set of component failures will be ensured. Finally, structure design with control design as opposed to existing procedures which add control after a structure is designed, will be integrated. This research will lead to a systematic theory of design for civil engineering structures, complete with a CAD workstation environment integrating identification, model reduction, control design, and structure design. The improvements in structural design could be significant when the two disciplines (structures and controls) are integrated into a single design process ***

该项目开发用于预测土木工程结构动态响应的分析方法，以及改善动态响应的新结构设计概念。 将建立具有某些建模不确定性以及静态和瞬态载荷中具有某些不确定性的结构的动态响应上界。 将确保各种设计目标的安全性能，包括承受最坏情况下的风荷载和地震激励的能力，以及存在一组指定组件故障的情况。 最后，将结构设计与控制设计相结合，而不是在结构设计之后增加控制的现有程序。 这项研究将导致一个系统的土木工程结构设计理论，完整的CAD工作站环境集成识别，模型简化，控制设计和结构设计。 当两个学科（结构和控制）被整合到一个单一的设计过程中时，结构设计的改进可能是显著的 *
