• Brick buildings for seismic prone areas

    In the course of this research, shaking table tests on real scale buildings have been conducted, as these tests deliver most reliable results. For this purpose, two mockups with different geometries were tested on 3D shaking tables, using a series of seismic records with increasing intensity.

    I got to use one of these tables to test high pressure boiler piping for nuclear power plants. So it turns out it's not the shaking and twisting that causes failure, but inside the pipes the earthquake creates vortexes and micro vortexes inside the product that slam into the inside walls causing internal structural damage until the pipe fails.
