Abstract
The project researches the possibilities offered by modern advanced technologies for the increase of safety of building structures and their influence on the building architecture. It is oriented toward the field of safety of residential buildings and as a consequence, toward the increase of safety of people and property in the building structures. The project is limited to earthquake and fire resistant safety of structures and their influence on the architectural design of modern residential buildings. As advanced technologies we consider all passive and active technological systems, that are built in the structure in order to increase its safety. Considering the earthquake safety these are various devices for base isolation systems, such as various bearings, dampers and systems for displacement reduction. Considering fire resistant safety, these are mostly advanced computer systems for surveillance, alarming, evacuation and fire extinguishing. Only technologically well versed architect will be capable to include all technological demands in the building architecture, as soon as in the phase of basic conceptual design, what only assures their maximal efficiency. Only the structures designed in this way might combine the architectural recognition, beauty and excellence with sufficient safety against eventual misfortunes during their projected lifetime. As one of the important practical results of the project we exalt also the preparations of guidelines for design of “Modern Safe European Competitive Residential Building”. The usage of earthquake isolation in this manner is completely new in our region and it might, as example, thoroughly change the directions for after earthquake renovation of Posočje region. The conclusions will however be usable also in other earthquake prone areas. We foreseen a divided research of different isolation systems for individual and multi-residential buildings. In the framework of the project we will research also the new ideas for simple economic base isolation of individual houses that is based on special base isolation system formed of sand foundation basin. The special attention will be given also to the possibilities to increase the safety of heritage valuable buildings and the increase of their earthquake and fire resistant safety. The project is divided into 8 Working Packages: WP1 - Detailed literature survey; WP2 – Determination of building mathematical models based on main architectural characteristics of individual and multi-residential buildings in Slovenia; WP3 – Earthquake isolation systems, analysis of selected models, comparison analyses; WP4 – Systems for the increase of fire resistant safety; WP5 – Analysis of the influence of technologically advanced systems to design of structures in architecture; WP6 – Synthesis of main conclusions; WP7 – Modern Safe European Competitive Residential Building and WP8 - Conclusions and dissemination of results.
Significance for science
It was proved that seismic isolations reduce the torsional effects in asymmetric structure. The correct selection of isolators can reduce the absolute values of displacements as well it can reduce the torsional amplifications. The effects of asymmetry can not be eliminated, however they can be transferred into base isolation system. With correct distribution of isolators the effects to the superstructure can be eliminated. We have also developed a new procedure for the usage of N2 method for base isolated structures. The method has been already implemeted into Eurocode 8, but it was not yet used for base isolated structures. We have proved that – with certain modifications – it can be used aslo for base isolated structures. It was also shown that earthquake resistant design principles can be used as a challenge for architectural design. We have developed a methodology for evaluation of the level of »earthquake architecture«. The method was tested and confirmed to be applicable also for selected practical examples. The doctoral thesis of Tomaž Slak confirms the research results.
Significance for the country
The results of the project and its desimination enhance the usage of seismic isolation for multi residetial buildings in Slovenia. At the moment such structures - except viaducts - do not exist in Slovenia. It was shown that the usage of seismic isolation is appropriate for special bulidings, such as buildings with especially valuable content, for extremely irregular buildings and for buildings of architectiral heritage. The design of seismic isolation is an elaborated process which requires an additional knowledge. For designers the presented usability of simplified N2 method will be of extreme importance. The transefer of passive house concept from earthquake non prone areas to the earthquake prone ones, such as is Slovenia, posses a question of their seismic safety. It was shown that the elongation of fundamental period of such individual houses can result in the increase of seismic forces and that the application of such structural systems in Slovenia needs some caution. The developed simplified method could help designers to judge the acceptability of particular passive house in every particular case. The hypothesis that the thermal insulation can work as seismic isolation was not confirmed completely, since the horizontal stiffness of usual thermal isolation in passive houses is to big. The concept of shear shift in the thermal isolation was also analyzed as a concept of earthquake fuse. It was concluded that it works only for stronger ground motions and that its usage in practice is still questionable. A side product of the research is also the geographical presentation of earthquake resistant safety of multi-residential buildings. The analyses were based on Census of population in 2002. It was shown that the safety of multi-residential buildings in Slovenia is questionable and that only half of the buildings conform to existing standards. For earthquake safety it was shown that the most endangered are the buildings with 5 or more stories built before 1981. Such buildings should be retrofitted as soon as possible. Their number amounts to 1188. There are 23.721 apartments in such buildings with total floor area 1.263.921 m2. In cooperation with Tromo d.d. we have transfer the project conclusions also in the practice. We have analyzed their warehose steel structure in Trebne and perform the analsys of seismic isolated and fixed based structurel variants for various levels of structural asymmetry.
