A contribution to the development and improvement of the design codes is considered to be the key result of the research. In such a way the results bring by far the most multiplied effect in the practice, safety and economy. Despite the fact that the project has been carried on for only one year, two pre-normative documents were already published. The first one provides the guidelines for the design of a precast structure with cladding panels as a whole. This aspect of design has never been understood correctly. Designers typically considered that claddings did not interact with the structure in the direction in the plane of the panels. However the displacement tolerances do not allow for such assumption in the case of strong earthquakes. This led to serious damage and even collapses in the past. Even the designers were aware of this problems they would not have procedures and tools to address them properly. Based on the research presented in this report, the well needed guidelines providing the complete design process were published in the European Joint Research Centre technical report. Activities are going on to adopt parts of these rules in Eurocode 8.

COBISS.SI-ID: 7584097A contribution to the development and improvement of the design codes is considered to be the key result of the research. In such a way the results bring by far the most multiplied effect in the practice, safety and economy. Despite the fact that the project has been carried on for only one year, two pre-normative documents were already published. The second one provides guidelines for the design of the specific connections between the precast cladding panels and the structure. These connections were designed (if they were at all) for the out-of-plane action. But, as it was described in the previous section, they were never designed for the in-plane action. Actually, the complex 3D interaction is a complex mechanism, which the designers were not able to address. However, the performance and safety of the cladding systems depends predominately on these connections. The fact that many different types of connections are used in the design practice further complicates the problem. Therefore, the design guidelines, procedures and formulas were prepared for the most typical connections used in Europe. The document is based on the in-depth understanding of the complex seismic behavior of the connections, which has been obtained in this project. The document was published in the European Joint Research Centre technical report. Activities are going on to adopt parts of these rules in Eurocode 8.

COBISS.SI-ID: 7588193The PI of this project organized a special session SS43 “Seismic behaviour of existing and innovative precast structural systems and connections” during the 16th World Conference of Earthquake Engineering. World conferences are attended by 4 thousands participants and therefore represent the biggest single event to dessiminate results and knowledge worldwide. After the review 16 papers were selected (3 of which were contributed by the research team) and presented whithin 2 two-hours sessions, which were well attended. The topics related to this project were discussed in detail and the results of the project arised considerable interest.
