项目摘要
Buildings are among the most complex and resource-intensive objects designed and built by humans. Buildings shelter occupants from multiple natural hazards, such as windstorms and earthquakes. Constructing and operating buildings for daily use consumes considerable energy, water, and material resources, and has associated environmental effects on ecosystems, human health, and the global climate. Current research and design approaches neither treat the risks from multiple hazards in a uniform way nor comprehensively address the environmental impacts of buildings. Most critically, these approaches do not systematically integrate sustainability and resilience over the lifespan of the various systems in a building. This research will create a science-based framework to design buildings that are both resilient to preserve their function in the face of multiple hazards and are also sustainable to reduce the adverse impacts on occupants and the environment. Designing healthier, more efficient, adaptable, and resilient buildings benefits the nation's ecological health, economic prosperity, and human welfare. Designing, building, and operating resilient and sustainable buildings requires interdisciplinary expertise from the fields of architecture, engineering, economics, and social science to carefully weigh various options and make informed decisions. This research will investigate a framework to support decision makers by drawing together a number of interdisciplinary research activities that quantify the functional performance of buildings in the face of adverse events, aim at a consistent resilience across multiple hazards (including earthquakes, wind, and floods), and measure the environmental impact of buildings during their lifespan. Given the risks due to multiple hazards, the response of each element of the soil, foundation, structure, and envelope system and their interactions wiil be evaluated to quantify damage, and in turn translate it into the primary resilience metrics: degradation of building function and time to recovery. A probabilistic approach will be used to account for uncertainties in demands and capacities and quantify resilience over a building's lifespan, factoring in the multiple hazards it will face as well as normal deterioration. As part of this process, resilience will be quantified for multiple hazards of buildings designed according to current codes and the results will be used to propose a new design concept for consistent resilience. Life-cycle assessment will be used to quantify environmental impacts and economic costs to evaluate sustainability. Finally, the results will be integrated into a decision framework in which resilience, sustainability, and economic costs are quantified over the lifespan of the building and used with social impacts to select among alternative soil-foundation-structure-envelope building system designs that are both resilient and sustainable.
建筑是人类设计和建造的最复杂、资源最密集的物体之一。建筑物使居住者免受多种自然灾害,如风暴和地震。建造和运营日常使用的建筑物消耗了大量的能源、水和物质资源,并对生态系统、人类健康和全球气候产生了相关的环境影响。目前的研究和设计方法既没有以统一的方式处理多种危害的风险,也没有全面解决建筑物对环境的影响。最关键的是,这些方法并没有系统地整合建筑物中各种系统的可持续性和弹性。这项研究将创建一个以科学为基础的框架来设计既具有弹性,在面对多种危害时保持其功能,又具有可持续性,以减少对居住者和环境的不利影响的建筑物。设计更健康、更高效、适应性更强、更有弹性的建筑有利于国家的生态健康、经济繁荣和人类福祉。设计,建造和运营弹性和可持续建筑需要来自建筑,工程,经济学和社会科学领域的跨学科专业知识,以仔细权衡各种选择并做出明智的决定。本研究将研究一个框架,通过将一些跨学科的研究活动结合起来,量化建筑物在面对不利事件时的功能性能,旨在对多种灾害(包括地震、风和洪水)保持一致的恢复能力,并测量建筑物在其使用寿命期间对环境的影响,从而为决策者提供支持。考虑到多重灾害所带来的风险,将评估土壤、基础、结构和围护体系的每个要素及其相互作用的反应,以量化损害,并将其转化为主要的弹性指标:建筑功能的退化和恢复时间。将使用概率方法来解释需求和能力方面的不确定性,并量化建筑物生命周期内的恢复能力,将其将面临的多重危险以及正常的退化考虑在内。作为这个过程的一部分,弹性将被量化为根据现行规范设计的建筑物的多种危害,结果将用于提出一个新的设计概念,以保持一致的弹性。生命周期评估将用于量化环境影响和经济成本,以评估可持续性。最后,研究结果将被整合到一个决策框架中,在这个决策框架中,在建筑的整个生命周期内,对弹性、可持续性和经济成本进行量化,并与社会影响一起,在具有弹性和可持续性的备选土壤-基础-结构-围护结构建筑系统设计中进行选择。
