Title: The effect of climate changes on buildings in Croatia
. Bernardin Peroš, M.Sc.C.E. Completed his Ph. D. in 1995. at the Faculty of Civil Engineering University of Zagreb Croatia. His Doctoral thesis was “Safety of structures with a dominant wind load”. He was a professor of eight courses at graduate studies and two courses at postgraduate-doctoral studies at the Faculty of Civil Engineering and Architecture University of Split. He was a professor at postgraduate studies at the Faculty of Civil Engineering University of Zagreb and Faculty of Civil engineering in Sarajevo, Bosnia and Hercegovina.
He was a vice –rector at the University of Split 2002-2004, and a dean of the Faculty of Civil Engineering and Architecture 2007-2010.
Scientific research: Safety of engineering structures and risk assessment under extreme actions. Publications includes: 92 scientific papers in journals and proceedings of scientific conferences. He was a mentor for a great number of postgraduate and doctoral theses. He has tree published books and two textbookks for students.
Membership: International Association for Wind Engineering (IAWE. ECCS –European Convention for Constructional Steelwork (ECCS); COST TU 0904 – Integrated Fire Engineering and Response. He is Member of technical boards for development of Croatian norms and regulations in civil engineering.
Nowdeys, we have the occurrence of large-scale damage in buildings (wind, snow, temperature, earthquake, etc.), all of which are caused by climate and other changes (planned global increasing the Earth's temperature to year 2100. in the amount of 1 - 6 °C).
Aditionally, the contribution of air pollution on a regional and global level, which refers to the general process of urbanization, should be added to the list. Studies of urban climatology have been developed at the level of theory and numerical modeling, while detailed research are close to determining the actual air quality in cities.
Here the urban climate can be understood by studying the changes that are primarily the result of changes in land use, resourcing of energy, moisture, circulation, and local air quality. All this leads to the consideration and the fact that the construction in its lifetime, is exposed a complex process of degradation, which primarily reflected to the reduction in their resistance and stability. The solution of this process of degradation is in determining structures durability in all phases of design, construction and use. Depending on the previous phases, maintenance can be preventive or existential.
The trend of structural reliability (decreasing resistance and increasing the load), can be the cause of the gradual (time) "damage", and as a result "unexpected damage" which was primarily caused by climatic and other changes in the useful life of the building. We're talking about a new trend in structural design, where the probability failure mechanisms of structures (pf) expressed in time pf(t):
FR(x,t) - the current "cumulative" distribution function of structural resistance,
fS(x,t) - the current "density" load structure.
The needed for further scientific expert research is as follows:
- Scientific studies of climate and other changes by aspect of extreme action on the structure.
- The monitoring of the behavior of significant buildings during use.
- Research Chemical- mechanical Civil engineering properties of a new generation of materials in accordance with modern technologies.
- Creating New Models - behavior of structures in the life of the relative state of the environment (climate and other changes).
