This paper presents an attempt to evaluate the feasibility and the effectiveness of an innovative foundation, which relies on the concept of local resonance, from a practical point of view. The proposed composite foundation integrates the well-established isolation system of lead rubber bearings in a layered structure form with reinforced concrete slabs, in order to tackle the inherent drawbacks of the bearing isolation. The novel foundation concept is implemented in a realistic structural geometry, designed according to the current standards, and the seismic performance is evaluated and compared against the corresponding typical base isolated and conventional stiff designed buildings. The results show that the proposed foundation concept achieves superior seismic performance in comparison to standard base isolation, providing an applicable and cost efficient solution in the framework of metafoundations. 5323 COMPDYN 2019 7 th ECCOMAS Thematic Conference on Computational Methods in Structural Dynamics and Earthquake Engineering M.

Information exchange between architectural design models and Thermal Energy Simulation (TES) tools still suffers from interoperability problems. The main challenge is to robustly translate the geometrical information required for TES. The current practice involves a cumbersome and iterative manual correction of the model between the architect and the engineer, which is prone to human errors. Interpreting the geometry solely based on the IFC file is not a trivial process due to its complex nature, in which different attributes are cross-linked to each other. To address this issue, an approach based on the Finite Element Analysis (FEA) is proposed, which aims to provide straightforward readability of geometrical information as well as a reliable and flexible thermal simulation. To demonstrate this approach, an IFC model of a residential building was transferred to a commercial FEA software and thermal analysis was conducted. Interoperability problems regarding robust transfer of geometrical information were not encountered and the process was deemed to be efficient. FEA also revealed another strength by providing thermal analysis of individual components of the structure. This can be employed in the early design stage by rapid prototyping of different components (e.g., geometry, thermal properties) and their role on the thermal performance of the whole structure. Results are presented by comparing the proposed approach with the current practice and the potential advantages are highlighted.
