The measurement procedure starts with the input of all the columns wind load design criteria into a specialised computer program. The calculation is carried out in accordance with the EN 40 standards and any additional loading criteria required by the customer (hanging baskets, banners etc.) This Initial structural calculation confirms whether or not a column with no deterioration would theoretically have sufficient structural integrity to withstand the loadings. After the column has been theoretically confirmed as suitable for the loadings, the actual test can commence.
Lasers are attached to the column at heights of approx 200mm and 2000mm above ground level, and then targeted towards the 3D camera adjacent to the column, then calibrated to take into account the surrounding conditions: the test equipment is then secured to the base of the column by means of a belt at ground level. Using a hydraulic arm, the test machine introduces a gradually increasing force until the required loading is achieved. The 3D camera registers all of the resultant reactions of the columns in the form of laser movements. The movements are mapped using a specialist 3D recorder which integrates into the measurement software. For analysis purposes, these recordings can be replayed in slow motion, or real time for customer’s evaluations.
The Rei-Lux testing method has been used for column testing since 1988. The Reilux Group has over 40 registered patents to its name. 15 of which are applicable to stability measurement, in particular, using innovation static and dynamic measurement techniques combined. The Rei-Lux Group continually develop these measurement techniques with the aim of optimising the test procedure increasing safety with regard to public lighting and introducing new innovative testing applications. |
