During this PhD I would like to use Finite Element Analysis to investigate the response of masonry infilled reinforced concrete frames as well as modelling other typical structural types used in non-seismic regions across Europe. A comparison of how these responses differ based on the cause of the earthquake (hydraulic fracturing vs mining) could also be carried out using seismogram data recorded at Bobrek and Groningen. Further seismogram data is to be released by IS-EPOS on the 30th of March 2018 which should allow for further verification of results. IS-EPOS is a programme funded by the European Union that has created a database of induced seismic data (Is-epos.eu, 2017). With the collection of a high volume of human induced seismic data it would also be possible to assess the level of attenuation relative the human induced earthquakes, and subsequently review the validity of current ground motion prediction equations (GMPEs) for small seismic events, such as that by Atkinson (Atkinson, 2015). A Eurocode 8 based comparison would be performed, using natural events as a benchmark and using hydraulic fracturing and mining data, adjusted to be spectrum compatible, to the same target design spectrum. This scaling can be done by scaling the induced data or by modifying the frequency content and phase of the induced data (Luco and Bazzurro, 2007). The above approach will allow me to investigate the effects in terms of damage related to induced earthquakes and to compare with those related to tectonic earthquakes. A research plan like this has the potential to impact for engineers (as primary stakeholders), policy makers and insurance companies.

在这个博士学位期间，我想使用有限元分析来研究砌体填充钢筋混凝土框架的响应，以及模拟欧洲非地震地区使用的其他典型结构类型。根据地震的原因（水力压裂与采矿），这些反应如何不同的比较也可以使用在Bobrek和格罗宁根记录的地震图数据进行。IS-EPOS将于2018年3月30日发布进一步的地震图数据，以便进一步验证结果。IS-EPOS是一个由欧盟资助的项目，该项目创建了一个诱发地震数据数据库（Is-epos.eu，2017）。随着大量人为地震数据的收集，还可以评估相对于人为地震的衰减水平，并随后审查当前地面运动预测方程（GMPEs）对小地震事件的有效性，例如Atkinson（Atkinson，2015）。将进行基于欧洲规范8的比较，使用自然事件作为基准，并使用水力压裂和采矿数据，调整为频谱兼容，以达到相同的目标设计频谱。这种缩放可以通过缩放感应数据或修改感应数据的频率内容和相位来完成（Luco和Bazzurro，2007）。上述方法将使我能够调查与诱发地震有关的破坏方面的影响，并与那些与构造地震有关的影响进行比较。像这样的研究计划有可能影响工程师（作为主要利益相关者），政策制定者和保险公司。
