Originální abstrakt

The paper is focused on complex approach for the determination of design value of resistance of prestressed concrete roof girders failing in shear. Beside commonly known safety formats for non-linear finite element analysis (NLFEA) as partial safety factor and approach according to EN 1992-2, an overview of some more complex, so-called semi-probabilistic methods, is given. Described safety formats are compared with numerical quadrature and small sample Monte Carlo (MC) type simulation, specifically Latin Hypercube Sampling (LHS). It is also shown that sensitivity analysis (SA) can be used to reduce the dimension of a stochastic model, which is definitely the very effective way to reduce computational requirements of reliability analysis.
