Structural engineering is a profession where failure can result in devastating loss of life and property. To protect structures during extreme loading conditions, several different structural control systems have already been developed and deployed. The investigations in the aftermath of recent natural disasters show that some structures with structural control systems survived with little or no damage; whereas other structures with similar control systems were severely damaged. These can be seen as testaments of both the potential of structural control and the need for research to employ these systems in a way to ensure consistent and robust structural response under extreme loading conditions.****To enable the development and widespread use of these control systems, it is necessary to develop performance based design codes which require knowledge of structural performance from real-time tests of structures equipped with these devices. Real-time Hybrid Simulation (RTHS) is ideal to address this need by only testing the critical components linked with computational models of the remainder of the structure and thus enabling a deeper and more economical investigation through a broader array of tests.****The proposed highly interdisciplinary research program will handle the common challenges related to the practical implementation of the structural control systems and successful application of RTHS. It will develop self-tuning controllers for RTHS and hybrid control systems. This will enable researchers who are not experts in control field to reliably perform RTHS of complex structural systems. The deliverables of the proposed research program also include a new, compact, and experimentally-validated hybrid control system. By presenting structural engineers with enhanced, reliable testing tools and control techniques, the proposed interdisciplinary program will contribute to the design and understanding of the next generation structures.*With the dissemination of the research findings, and through the highly qualified personnel that will be trained, this cutting-edge research program will provide Canada with a leading position in the field of structural testing and control.**

结构工程是一个职业，失败会导致毁灭性的生命和财产损失。为了保护在极端加载条件下的结构，已经开发和部署了几种不同的结构控制系统。在最近的自然灾害之后的调查表明，某些具有结构控制系统的结构几乎没有或没有损害。而其他具有相似控制系统的结构受到严重损坏。这些可以看作是结构控制潜力的证明，也可以看出需要研究这些系统的需求，以确保在极端负荷条件下的一致和稳健的结构响应。****为了使这些控制系统的开发和广泛使用，必须开发基于性能的设计代码，这些设计需要与这些设备配备的结构测试有关结构性测试的知识。实时混合模拟（RTHS）是仅通过测试与其余结构的计算模型相关的关键组件来解决这一需求的理想选择，从而通过更广泛的测试来实现更深入，更经济的研究。它将为RTHS和混合控制系统开发自我调整控制器。这将使不是控制领域专家的研究人员能够可靠地执行复杂的结构系统。拟议的研究计划的可交付成果还包括一个新的，紧凑的和实验验证的混合控制系统。通过向结构工程师提供增强，可靠的测试工具和控制技术，拟议的跨学科计划将有助于对下一代结构的设计和理解。
