SIMPLE QUICK 
​COST EFFECTIVE STRUCTURAL HEALTH MONITORING
USING

* BUILDING DRIFT DISPLACEMENT *
* ​BUILDING STIFFNESS *
​

JUST THREE UNITS NEEDED

After an extensive study by Taiwan National Chung-Hsing University, Departmental of Civil and Environmental Engineering, it has been proven that the health of a structure can be accurately diagnosed by only 3 seismic units. Using data from a large number of units over a number of earthquakes, the university was able to prove the ability of this new methodology to accurately show the health of a building. This breakthrough to provide rapid structural health diagnostics (RSHD) greatly reduces the cost to determine safety and also helps engineers to rapidly assess the health of a building enabling companies to return to work.
​SAVE TIME AND MONEY BY ASCERTAINING THE SAFETY OF A BUILDING RAPIDLY AFTER ​AN EARTHQUAKE
The cost effective Palert seismic sensor can be installed in strategic locations of a building or structure with the purpose of monitoring performance of key load bearing elements following an earthquake.

This is accomplished by a comparative analysis of the before and after resonant frequency profiles and rigidity to ascertain the possibility of structural damage. Even with only 3 units in a building, the system can provide accurate analysis of structural health.

Rapid Structrual Health Diagnostics - System Structural Health

RAPID ANALYSIS

​Further structural modelling using Palert data will allow engineers to quickly establish a detailed picture of the impact that a seismic event might have had on a given building or structure.

All of this allows the engineers to concentrate on the least affected buildings, enabling companies to return to work as quickly as possible. It also ensures that engineers do not miss buildings that appear to be structurally   sound but in fact have some underlying weakness.
