Advanced Control and Simulation of Structural Systems

结构工程是一个专业，失败可能导致毁灭性的生命和财产损失。为了在极端载荷条件下保护结构，已经开发和部署了几种不同的结构控制系统。在最近的自然灾害后的调查表明，一些结构控制系统的结构幸存下来，很少或没有损坏，而其他结构类似的控制系统受到严重破坏。这些可以被看作是结构控制的潜力和研究的需要，以确保在极端载荷条件下的一致和强大的结构响应的方式使用这些系统的测试。 为了使这些控制系统的开发和广泛使用，有必要开发基于性能的设计规范，这些规范需要从配备这些设备的结构的实时测试中获得结构性能的知识。实时混合仿真（RTHS）是解决这一需求的理想方法，它只测试与结构其余部分的计算模型相关联的关键部件，从而通过更广泛的测试进行更深入、更经济的调查。 拟议的高度跨学科的研究计划将处理与结构控制系统的实际实施和RTHS的成功应用相关的共同挑战。它将为RTHS和混合控制系统开发自校正控制器。这将使研究人员谁不是控制领域的专家，可靠地执行复杂的结构系统的RTHS。拟议的研究计划的交付成果还包括一个新的，紧凑的，经过实验验证的混合动力控制系统。通过向结构工程师提供增强的，可靠的测试工具和控制技术，拟议的跨学科计划将有助于下一代结构的设计和理解。 随着研究成果的传播，并通过将接受培训的高素质人员，这一尖端研究计划将为加拿大提供结构测试和控制领域的领先地位。

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.
