In the article a review of modern software systems allowing calculating the distribution of temperature fields in a structure in time, without loading and with it (the fire resistance limit of structures) under conditions of a special fire load has been given. The algorithm of the finite element method is used for the calculations, on which each of the considered complexes is based. Specifically: Sofistik, Abaqus, Normcad, Ansys, Robot structure. Comparative analysis has been made from the point of view of intuitive user interface, the possibilities of modeling various conditions and fire regimes, tools for communication with other software complexes and the format of output of results. The results demonstrating the capabilities of the post-processor Sofistik have been presented.

“…Fireproofing charring compositions are frequently used and well-known: first patents were published in 1930s [1,2]. A significant amount of researches [3][4][5][6][7][8][9] which purpose is to improve fire resistance of building constructions and materials shows that the work on enhancing the properties of swelling compositions continues nowadays. As intumescent materials exist for such a long period of time, researchers have found the optimal technological complex for producing intumescent compositions which ensure effective fire protection of constructions and materials.…”

The paper overviews the operational properties of charred layers which are forming as a result of thermolytical synthesis of intumescent coatings, and the ways of enhancing those properties using different additives mixed with initial intumescent composition. Methods including differential thermal analysis, thermogravimetric analysis, microscale calorimetry and scanning electron microscopy were used to investigate the modified intumescent compositions and the properties of charred layers formed from them. Results show that additives tend to change the microstructure of char which undergoes some transformations; it is proven by increase in volume and stability. Also it is shown that melamine-aldehyde resin was detected in the microstructure of char, and it is a step forward in forming a holistic conception of intumescents operating.

“…1a) and one additional parameter of the incident shock (for example, its strength 1 J or its amplitude 1 p  ). Here the strength 1 J of the incident shock is the static pressure ratio across it, and the amplitude 1 p  is the difference between pressures while crossing the shock (the shock overpressure which is especially important in problems of blast reflection [1,2] and corresponding structural survivability [3][4][5] problem corresponds to variation in the wedge angle  in the problem of unsteady (quasisteady) reflection of propagating shock of the same strength. Thus, the non-monotonic dependence of the mechanical loads behind reflected unsteady shock from an inclined surface appears from the non-monotonic pressure variation downstream the point of steady reflection.…”

The regular reflection of an oblique steady shock in supersonic gas flow is considered. The static pressure extremum conditions after the point of reflection of the shock with fixed strength depending on oncoming flow Mach number are determined analytically. The obtained results are applied to solution of the mechanically equivalent problem of the reflection of a propagating shock from an inclined surface. Non-monotonic variation of the mechanical loads on the obstacle with respect to its inclination angle is shown; the obstacle slope angles that correspond to pressure minima downwards of the unsteady shock reflection point are determined analytically.
