It is increasingly evident that buildings are facing mounting risks due to the ever-changing hazards, and the**tightening requirements and expanding complexity of building designs. Due to the tight coupling between**building systems of different types, failures can cascade across a building and its operation. This state would**benefit from an integrated approach to risk assessment in the engineering design process that can model and**depict cascade effects.**Completion of the research to meet this challenge is planned through four modules intended to study the**potential of a new workflow to augment building design efforts and a new method to support the workflow.**Module one concerns experimenting with creating a 3D scan of existing buildings and Module two concerns**converting these into Building Information Models (BIM). Combined, these modules are about determining**how suitable data can be produced of a building to model cascading risk and may include augmentation with**other information about the building or its operation such as condition assessments or other simulations of the**building (e.g., structural) to produce a workflow that can populate risk parameters. Module three is the creation**of a custom VR simulation that ingests the data from the other modules and allows clients to experience the**cascade of hazard effects across building components. The final component is the creation of a risk assessment**and decision support system within the simulation platform that incorporates a cascading risk computation in**concert with the building information in the simulation to support engineering design.**Canada benefits through the creation of innovative engineering and technology, further advancing Canada's**position as a world leader by providing our engineers with new capability. Further, application of the capability**domestically can serve to reduce the risk to Canadian buildings.

越来越明显的是，由于不断变化的危险，以及建筑设计的严格要求和不断增加的复杂性，建筑物正面临越来越大的风险。由于不同类型的建筑系统之间的紧密耦合，故障可能会在建筑物及其操作中级联。这种状态将 ** 受益于工程设计过程中风险评估的综合方法，该方法可以模拟和 ** 描述级联效应。计划通过四个模块完成研究，以应对这一挑战，这些模块旨在研究新工作流程的潜力，以增加建筑设计工作和支持工作流程的新方法。模块一涉及实验创建现有建筑物的3D扫描，模块二涉及将这些转换为建筑信息模型（BIM）。结合起来，这些模块是关于确定 ** 如何产生建筑物的合适数据来对级联风险进行建模，并且可以包括用 ** 关于建筑物或其操作的其他信息进行增强，诸如 ** 建筑物的状况评估或其他模拟（例如，结构化）以产生可以填充风险参数的工作流。第三个模块是创建一个自定义的VR模拟，该模拟从其他模块中获取数据，并允许客户体验建筑组件之间的危险效应级联。最后一个组成部分是在模拟平台内创建风险评估 ** 和决策支持系统，该系统将级联风险计算与模拟中的建筑信息相结合，以支持工程设计。加拿大受益于创新工程和技术的创造，通过为我们的工程师提供新的能力，进一步提升加拿大作为世界领导者的地位。此外，在国内应用这种能力 ** 可有助于减少对加拿大建筑物的风险。
