However, the modeling of assembled cross-laminated timber components has been studied only scarcely. The three-dimensional p-version of the finite element method, which is characterized by hierarchic high-order shape functions, is well suited to consider coupling and support conditions. Furthermore, a small number of degrees of freedom can be obtained in case of thin-walled structures using p-elements with high aspect ratios and anisotropic ansatz spaces. In this article, a model for cross-laminated timber assemblies made of volumetric high-order finite elements is presented. Two representative types of connections are investigated, one with an elastomer between the cross-laminated timber components and the other without. The model is validated, and suitable ranges for the stiffness parameters of the finite elements which represent the junctions are identified.

Low-energy-consumption or so called pas sive- houses built of timber are known to combine an environmentally-friendly construction principle wit h high expectations on aesthetics and modern architecture. The number of multi-storey residential buildings erecte d in timber construction has been steadily increasing in the last few years, also in urban areas and centres. Compared to similar construction projects built in concrete the design of a multi-storey building in timber con struction is more demanding and challenging to the architect and construction engineer. Reasons for this are tougher requirements on fire safety regulations in these bu ildings as well as the absence of sufficient realized examples and design tools for the proof of performance of vibrat ion control and sound insulation. In a current project [1] these design tools shall be further developed by using a combination of FEM and SEA for the proof of perform ance.

T1 - FEM based prediction model for the impact sound level of floors T2 - EURONOISE 2008- Conference Proceedings N2 - Up to now the research and developmen t in the field of building acoustics is based mainly on measurements. The consequence is that the development and optimization of a new building component is a very tedious and expensive task. A considerably reduction of these costs could be achieved, if the optimization relying on measurements would be replaced – at least to some extent – by a computational prediction model. Motivated by these aspects a method is presented for using finite element techniques to estimate the impact sound level from lightweight floors. The overall approach consists of the three-dimensional modeling of the structure and the excitation source (tapping machine), the subsequent moda l- and spectral analyses an d the computation of the radiated sound from the ceiling.

T1 - Optimization of lightweight floors in the low frequency range with a FEM based prediction model T2 - DAGA Tagungsband N2 - The impact noise transmission at low frequencies is a well known problem of lightweight floors, which is treated in many publications. A satisfying solution, considering the different construction principles of lightweight floors, could not be found so far. To overcome this problem a FEM based prediction model for the optimization of the floor construction and the improvement of the impact sound insulation has been developed and applied in a current research project at th e TU München. The details of the prediction model were published in [1]-[3]. This contribution gives an overview of the prediction model and shows the results of the computations and the construction rules developed for optimized lightweight floors.

T1 - Modelling the excitation force of a standard tapping machine on lightweight floor structures JF - Journal of building acustics N2 - Up to now the research and development in the field of building acoustics is based mainly on measurements. In consequence the development and optimization of a new building component is a very tedious and expensive task. A considerable reduction of these costs could be achieved, if the optimization relying on measurements would be replaced – at least to some extent – by a computational prediction model. For these models it is necessary to represent not only the component and the adjacent rooms but also the excitation in a suitable way. This paper gives an overview of models for the excitation generated by a standard tapping machine taking into account the interaction between the impacting steel cylinders of the tapping machine and the vibrating surface of the floor.
