Our technical team is currently working on a series of articles to highlight considerations associated with various applications.
To understand tilt & angular distortion appears to be quite simple. However, since late 1950s many reference professionals and academics have been trying to derive relationships between tilt & angular distortion and the risk of damage to buildings.
Regarding instrumentation, more often than not it looks like there are several options to monitor tilt & angular distortion. A good understanding of the behaviour of the structure is needed, together with careful planning and design for instrumentation and monitoring.
However simple they may appear, load cell installations pose unexpected questions. These challenges include load range, alignment, positioning and diameter consistency, as well as temperature effects, all of which will have significant impacts on the outcome.
Deep piezometer installations create a range of challenges, with the deeper the installation the larger the impact. These challenges include the positioning of the response zone, placing of the piezometer, protection of the sensor and cable and backfilling of the borehole all of which will have significant impacts on a successful installation.
