Technical conditions concerning the quality of shallow foundations material according to en and BAB87

Građevinske konstrukcije su tokom svog životnog veka izložene različitim agresivnim uticajima koji izazivaju njihovu degradaciju i smanjuju trajnost. Kada su u pitanju konstrukcije od armiranog betona, istraživanja su pokazala da se problem njihove trajnosti može svesti na probleme degradacije betona i armature u betonu. U radu je najpre ukratko data analiza agresivnih uticaja, a zatim predstavljene mere za sprečavanje degradacije betona i armature kod plitkih temelja. Posebna pažnja je poklonjena određivanju zaštitnog sloja betona temelja i proračunu temelja na osnovu graničnih stanja upotrebljivosti. Dat je paralelan prikaz ovih mera prema našem Pravilniku (BAB 87) i Evropskim normama (EN - Evrokod 2). . Engineering structures during their service life are exposed to a variety of aggressive actions causing their degradation and reducing durability. In reinforced concrete structures, the problem of their durability can be reduced to concrete and reinforcement degradation problem. In the paper, an analysis of aggressive influences was given, and then measures for prevention of concrete and reinforcement degradation in shallow foundations. Special attention was paid to the determination of the protective layer of foundation concrete and the calculation of the foundation on the basis of limit states of serviceability. A parallel presentation of these measures was provided, according to the national code (BAB 87) and European norms (EN - Eurocode 2).
