Vibration Monitoring to Achieve Net Zero Carbon: Yorkshire Region April 2022 Technical Talk



Speaker Bio

Hassan Moharram is a product owner for structural software at DNV and formerly a structural engineer and design manager at Arup. Hassan develops and integrates digital technology in the design of sustainable energy infrastructure, aiming at maximising asset potential and accelerating the net-zero emissions goals in the built environment.

Talk Synopsis

Buildings contribute around 40 percent of greenhouse gas emissions worldwide. Therefore, it is critical that architects, engineers, and property owners, understand their role in reducing the sector’s carbon footprint. The last decade witnessed an increase in smart building technologies that reduce both operational and embodied carbon. However, the life-extension and reuse of existing structures can be a very effective and low-cost carbon saving strategy.

A significant challenge that we face when working with existing buildings is the uncertainty of the current structural performance, including how the building was altered, aged, or damaged over its life. We also need to realise all the unintended contributions of non-structural systems to the stability of the building and quantify the impact of the required modifications.

In this talk, we will introduce a data-driven and performance-based design concept that allows us to Reverse Engineer a building structure and establish its actual performance. The process uses vibration monitoring coupled with high-fidelity structural models in a concept called Probabilistic Model updating. In this process, a structural model is calibrated to match the measured dynamic properties and provide a probability of the health condition of the structure. A case study on the use of such methods on Portland House demonstrates how this digital approach can improve the viability of reuse.
