Bridge structures zero emissions

项目摘要

The Bridge structures with zero emissions project is with MTC. For the construction industry, the two critical challenges presented by the Absolute Zero report are the closure of all blast-furnace steel production and the fact that we have no scalable practical alternatives to Portland cement. Further implications change the context of construction, there won't be enough emissions-free electricity to support electric vehicles at today's levels and consequently demand for public transport will rise. What does this mean for the future of bridge construction?The proposed PhD would be "T-shaped" - a first year scoping the topic broadly, sampling industrial opinion, and identifying possible technical interventions. Years two and three would then aim at more technical projects - looking in detail at technological interventions that show the most promise from the results of the first year. Two example key technical questions that arise as we think about zero emissions bridges and could be of real interest and value are:How can we ground a bridge without cement/ concrete. For example, what are the durability implications of steel attachments? What of vibrations, etc.What is the maximum performance would could get from constructing bridges with emissions-free materials: for example, what is the optimal stone bridge, if built with waterjet-cut stone, and very precise geometry? What is the tallest, strongest timber bridge possible?

零排放桥梁结构项目与MTC合作。对于建筑行业来说，绝对零度报告提出的两个关键挑战是关闭所有高炉钢生产，以及我们没有可扩展的实用替代品来替代波特兰水泥。进一步的影响改变了建设的背景，没有足够的零排放电力来支持今天的电动汽车水平，因此对公共交通的需求将会上升。这对未来的桥梁建设意味着什么？拟议的博士学位将是“t形”的——第一年将广泛地研究这个主题，抽样工业界的意见，并确定可能的技术干预措施。然后，第二年和第三年将着眼于更多的技术项目——详细研究从第一年的结果中显示出最大希望的技术干预措施。当我们考虑零排放桥梁时，会出现两个关键的技术问题，这些问题可能会引起我们的真正兴趣和价值：我们如何在没有水泥/混凝土的情况下建造桥梁。例如，钢附件的耐久性含义是什么？用无排放材料建造桥梁的最大性能是什么？例如，如果用水射流切割的石头和非常精确的几何形状建造，最理想的石桥是什么？最高、最坚固的木桥是什么？
