Tiivistelmä
The discovery and development of falling weight deflectometers (FWDs) in construction has improved the quality of buildings all around the world by letting engineers understand not only how resistant their base is against compressive loads applied on top, but also how the base is reacting to different surrounding factors. Nevertheless, knowing these factors many different methods have been created to help building foundation bases achieve the desired performance.
The main purpose of this report was to compare and analyze the differences and similarities between “LOADMAN II” and “TERRATEST 4000” light falling weight deflectometers (FWDs). To analyze these devices, several visits in construction sites have been conducted in Finland and abroad, where the devices were used to execute measurements through appropriate and exact procedure. The research has been realized using the before mentioned devices as well as applications such as AutoCAD and Excel for drawings and data, respectively. The results of this research interpreted the differences and similarities between the devices in a few different areas of study such as data input, data output, procedure of measurement, advantages, disadvantages etc.
In conclusion, the results of this research interpreted the behavior from both devices in different circumstances, explained their functionality and finally, it deduced what should and should not be done during the procedure. The results achieved from these measurements also highlight the importance of different project size capacity, procedure of working and output values for further analyzing.
