Pravděpodobnostní přístup k určování požární odolností kombinovaného prutu
Rieger, M. ; Pustka, D. ; Marek, Pavel
Determination of the final fire resistance of composite columns made of concrete filled hollow sections. Calculation is based on achievement of critical temperature on steel tube with respecting section ratio Am/V. Final fire resistance is determined respect to influence of concrete filling, second order stability modeling and fully probabilistic approach. Article demonstrates application of the probabilistic method SBRA (Simulation Based Reliability Assessment) in fire resistant calculation.

Application of SBRA method in the framework of probabilistic assessment of a supporting system which consist of slender steel-concrete columns
Pustka, David ; Čajka, R. ; Marek, Pavel
Modern reinforced concrete structural systems, consisted of various slender members (i.e. columns, piers, frame legs, etc.), are used more frequent than ever. Effects of external forces on these structures are significantly dependent on their deformations. Reliability assessment of such structures should be thus based on equilibrium of internal and external forces acting on deformed structures. One of these methods is also SBRA (Simulation-Based Reliability Assessment) method, documented in e.g. [1], [2], [3], [8]. Potential of this method is briefly outlined in the study dealing with the reliability analysis of a structural system made by slender reinforced concrete columns. This study is introduced in the full version of this paper stored on the enclosed CDROM.

Posudek použitelnosti železobetonových desek s aplikací metody SBRA
Pustka, D. ; Marek, Pavel
The goal of the paper is serviceability assessment from the view point of limit deflections of simply supported reinforced concrete one-way slab. The slab is exposed to uniformly distributed dead load and imposed load. Most of input quantities are considered as random variables, including loadings, and described by corresponding bounded histograms, the assessment is performed using the fully probabilistic SBRA method.

Durability of steel structures exposed to corrosion
Pustka, D. ; Marek, Pavel
In the area of structural design increasing attention has being given to the development and application of new progressive methods allowing for complex reliability assessment of structures with consideration time-dependent effects. One of these powerful methods allowing this complex reliability analysis is SBRA method. The potential of this method is briefly outlined on example of a steel component exposed to time-dependent corrosion effects.
