The main objective of the proposed research is to integrate advanced hybrid (experiment-analysis) multiplatform simulation technology with the industry partner's development, S-Frame Analysis. In current structural assessment and design practices, a structural system is modelled with an equivalent linear system. To evaluate the structural elements' behaviour in detail, engineers need to develop a refined model of the element and apply boundary conditions obtained from the system-level analysis. This two-stage approach does not accurately capture the interaction between the investigated element and the structural system, which leads to the inaccurate assessment of system-level performance. To overcome such limitations, a hybrid simulation technology has been developed. In the hybrid simulation method, critical components in a structural system can be modelled as experimental specimens, while the rest of the system is modelled numerically. The concept has been extended to multi-platform simulations in which the experimental specimens are replaced with numerical substructure modules. However, this simulation method has only been applied to research projects in academia, as the application of the simulation method to engineering practice requires significant effort and training. In this project, the aim is to implement the advanced simulation method using the industry partner's engineering software. This will allow us to verify the simulation method through a numerical multi-platform simulation and a hybrid simulation with a small-scale experimental specimen. The successful completion of the project will allow structural engineers to adopt advanced simulation methods, which will ultimately contribute to a society that is safer from structural failure.

拟议研究的主要目标是将先进的混合（实验分析）多平台仿真技术与行业合作伙伴的开发 S 框架分析相集成。在当前的结构评估和设计实践中，结构系统是用等效线性系统建模的。为了详细评估结构元件的行为，工程师需要开发元件的精细模型并应用从系统级分析中获得的边界条件。这种两阶段方法不能准确捕捉所研究的元素和结构系统之间的相互作用，从而导致系统级性能的评估不准确。为了克服这些限制，开发了混合仿真技术。在混合模拟方法中，结构系统中的关键部件可以建模为实验样本，而系统的其余部分则进行数值建模。该概念已扩展到多平台模拟，其中实验样本被数值子结构模块取代。然而，这种模拟方法仅应用于学术界的研究项目，因为将模拟方法应用于工程实践需要大量的努力和培训。在该项目中，目标是使用行业合作伙伴的工程软件实施先进的仿真方法。这将使我们能够通过数值多平台模拟和小规模实验样本的混合模拟来验证模拟方法。该项目的成功完成将使结构工程师能够采用先进的模拟方法，最终将为一个更安全、免受结构故障影响的社会做出贡献。
