Tiivistelmä
The thesis aimed to check whether FEM is a good tool for checking the vibration performance of CLT slabs supported by steel-concrete composite beams DELTABEAM® by comparing the results from Autodesk Robot, hand calculations, and measurements taken on site. Another purpose of the thesis was to develop instructions for running a vibration analysis of CLT slabs in Autodesk Robot Structural Analysis Professional software.
Alongside FEM analysis, hand calculations were done according to SCI PUBLICATION P354 to review the accuracy of FEM results. To support the theoretical part, a concrete study case was taken – the floor structure of Hopealaakso kindergarten located in Helsinki, where the measurements have been taken, analyzed, and compared to come up with a conclusion.
The results of the study case proved that FEM is a reliable tool for checking the vibration performance of CLT floors supported by DELTABEAM®. The outcome of the thesis is a written instruction on how to utilize Autodesk Robot FEM program for carrying out the floor vibration analysis and it can be used by the employees of Peikko Finland Oy.
