Opis:
The non-linear structural analysis is considered as a basic design procedure, which is used for checking of the structural robustness in accidental design situation. It is explained by following reason: a non-linear structural analysis based on realistic constitutive relations for basic variables (average values) makes possible a simulation of a real structural behavior. It should be pointed that, implementation of the non-linear structural analysis in design of concrete structures requires an alternate approach to safety verification. The paper presents a new approach to safety format for non-linear analysis of RC structures subjected to accidental loads.

Opis:
The article presents the result of the implementation of innovative design solutions techniques during the construction of the building of the “WORLD CLASS” Fitness Club in Minsk with usage of the performance-based approach. Proposed design solution of building include the composite structures (plane frames consists of steel-concrete columns and delta-beam), prestressed hollow core slabs. The cantilever parts of the building were designed as a complex post-tensioned monolitic structure, including cantilever beams and slabs with a maximum length of 12 m, monolitic walls and pylons. The example of performance criteria verification (structural serviceability) with usage different methods presents.

Opis:
Currently the CEN/TC250 is completing the development of a new (second) generation of Structural Eurocodes. The checking of robustness remains one of the important stages in the design of structural systems. Recommended design strategies for robustness checking are based on provisions given in actual EN 1991-1-7. A Non-linear pseudo-static analysis is widely used by following reasons: a non-linear structural analysis based on more realistic constitutive relations for basic variables makes possible a simulation of the real structural behaviour. Implementation of the non-linear pseudo-static analysis for assessment of the structural system in accidental design situation requires an alternate approach to safety format. The paper presents an innovative approach to safety format calibration for non-linear analysis of RC-structures subjected to accidental loads.

Opis:
Porosity is one of the major problems in casting operations and there are several discussions in the literature about the porosity formation in aluminum castings. Bifilms are the defects that are introduced into the melt by turbulence. They can be detected with reduced pressure test and presented numerically by measuring bifilm index. The measure of bifilm index is the sum of total oxide length given in millimeters from the cross-section of reduced pressure test sample solidified under 0.01 MPa. In this work, low pressure die casting (LPDC) unit was built in an attempt to enhance the producibility rate. The unit consists of a pump housing that was placed inside the melt in the melting furnace where the pressure was applied instead of the whole melt surface. It was observed that the melt quality of A356 alloy was deteriorated over time which had led to higher porosity. This was attributed to the increased oxide thickness of the bifilm by the consumption of air in between the folded oxides. A relationship was found between bifilm index and pore formation.
