I calm down the restlessness working on side-projects that involve new learning through buiding stuff. Most of them involve software and hardware concepts and some selected projects can be seen below.

  • Interactive App: Data visualisation from instrumented regions of the new Civil Engineering Building of the University of Cambridge. This is an interactive online application I developed to offer a virtual insight into the new Civil Engineering Building at the University of Cambridge. Users can access the Web App to interact with 3D models of instrumented areas of the building and see visualisations of the data and learn engagingly about sensing techniques and fibre-optic technology. It was launched at the 2021 Cambridge Festival where I hosted the event: 'Bringing buildings to life: Smart infrastructure at the Civil Engineering Building'.

  • Strong-Motion Processing Tool: Open-Source Web-App for the processing of earthquake strong motion recording information. Currently under development, this tool aims to contribute to the understanding of some cornerstone concepts in Earthquake Engineering, such as Elastic and Inelastic Response Spectrum. Besides, offers the possibility of visualising and processing strong-motion data on the fly. The processing involves baseline corrections, filtering techniques, among others; that are indispensable for several methods in Earthquake Engineering practice and research. More tools to be set upon the current building blocks are coming soon, as the computation of rotated spectrum, correction and filtering of several records at once, ground motion selection records based on seismic hazard, among others. You can already play following the link above.

  • Open-Source Seismic Hazard Curves: Web-App for the computation of seismic hazard based on novel intensity measures (IMs). The merits of the spectral acceleration of the fundamental period, Sa(T1), are incontestable. However, for collapse risk assessment, novel IMs have been shown to perform better (i.e., efficiency and sufficiency). As is the case of the spectral acceleration averaged over a period range, Sa avg. However, the development of probabilistic seismic hazard information in terms of these novel IMs is needed, and this endeavour is on that direction. This is an ongoing project in collaboration with Professor Eduardo Miranda and PhD Student Pablo Heresi from Stanford University. More information in the following links:

  • Low-cost Shaking Table: Educational tool to underpin structural dynamic concepts. It is a small shaking table that allows to reproduce wavelets, periodic oscillations and non periodic ones such as earthquake acceleragrams. It is powered by a brushless servo motor and it is controlled by an Arduino board. For the data-acquisition I used another Arduino board and I assembled some wired-sensors using low-cost but accurate accelerometers, in order to record the response of the system.

  • Reaction Frame for Cyclic Loading (100 Tons): Experimental campaign undartaken in Chile where I lead the construction and assembly of a reaction frame, as well as the control, calibration and data acquisition solutions to perform my experiments on built-up T-stub connections for steel structures.

  • Low-cost Vibrations Sensor: This is an ongoing project where I am developing a wireless device for sensing motion structural response, oriented to be used in civil structures, built completely with off-the-shelf electronic components. This project is possible thanks to the support of the The Earthquake Engineering Field Investigation Team (EEFIT) of the Institution of Structural Engineers, as part of the EEFIT Research Grant Scheme 2018.
