Abstract:
Modern structures are becoming more and more slender but with improved stiffness with use of large number of materials in combination, making the predictions of dynamic characteristics of such structures extremely difficult for the analysis using commercially available general purpose finite element softwares. On the other hand, if a building floor is properly excited and the input force and the resulting responses are accurately measured with proper hardware, the dynamic characteristics can be found out without much error. In direct method of analysis, the input force is generated by the load cells provided. The present work is focused on actual physical measurement of input force of a reaction mass shaker to a typical building floor to determine the floor dynamics. A case study on a double storey Laboratory floor establishes the advantages of this kind of combined experimental and numerical methods.
