Design of Controllable Civil Engineering Structures

9403592 Skelton这个项目开发了预测土木工程结构动力响应的分析方法，并提出了新的结构设计概念来改善动力响应。对于具有一定建模不确定性的结构，以及在静力和暂态载荷中具有一定不确定性的结构，建立了结构动力响应的上界。将确保各种设计目标的安全性能，包括在出现一组特定组件故障的情况下承受最坏情况下的风荷载和地震激励的能力。最后，结构设计将与控制设计相结合，而不是现有的在结构设计后添加控制的程序。这项研究将形成一个系统的土木工程结构设计理论，并建立一个集识别、模型简化、控制设计和结构设计于一体的CAD工作站环境。当两个学科(结构和控制)被集成到一个设计过程中时，结构设计的改进可能是显著的*

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 ***
