This article provides an example of the calculation of eccentrically compressed reinforced concrete elements exposed to dynamic loads and fire effects. The dynamic factor for the concrete under regular conditions is available, and it exceeds one in any case. However, in case of a fire exposure, the value of this factor varies from 0,4 to 0,8, depending on the loading rate and temperature. The value of the dynamic factor was identified in the course of an experiment; thereafter, the pattern of influence of the dynamic effect caused by the progressive collapse of buildings and produced onto the bearing capacity and fire resistance of compressed elements of the pylon and the column was identified. ANSYS 12.1 software package was employed to perform the fire resistance analysis of the pylon on the 1st floor of a 59-storey building. The problem was modeled in the 3D formulation. It represented a pylon exposed to static loading and standard fire conditions. For comparison purposes, bearing capacity values were calculated for different values of the thermal load.The calculation of temperature fields was based on the resolution of boundary value problems of transient heat conduction in capillary-porous bodies.The solution to the problem of the four-sided fire exposure at standard fire temperature values was obtained in characteristic points of the support structure to assess the change in its load-bearing capacity.It is proven that dynamic effects of a fire reduce the bearing capacity of columns by 40 %. Therefore, the analysis of the bearing capacity of structures in terms of their fire resistance should take account of the possibility of progressive collapse of buildings.

The authors draw attention to possible problems in the process of construction and operation of monolithic frame buildings, construction of which is now widespread. It is known that cracks can often appear in the facade and side walls. The size of the cracks can exceed the allowable limits and repair does not lead to their complete elimination. Also cracks significantly mar the appearance of a building. Thus, the relevance of this study lies not only in fuller understanding of the operation of walls, but also in the ability to prevent undesirable effects.The authors calculated temperature effects for boundary walls of the building blocks made of heavy concrete. The original dimensions of the walls conformed to a grid of columns for the majority of residential and public buildings.The stress-and-strain state of the walls in case of temperature changes is observed in detail, including the transition from sub-zero to above-zero temperatures within the same section (wall). It was revealed that the temperature variations within the established limits may cause stress-and-strain state in the walls, in which the temperature tensile stresses can exceed the tensile strength of materials. The article contains effective means of reducing thermal strains, which can prevent temperature and shrinkage cracking.

The authors investigated tear resistance of a faсade expansion anchor from a steel socket - a material possessing greater strength properties than nylon expansion anchor socket, which allows defining the properties of a socket, but not of a wall material. The authors obtained a load diagram consisting of four areas. Area 1 almost corresponds to Hook's law up to peak force. Area 2 is an abrupt decrease of tearing force. Area 3 is a smooth descending branch up to ultimate deformation corresponding to product certificate. Area 4 is a final withdrawal of an expansion anchor as a inclined line. The authors offered a hypothesis about genesis and destruction of microdefects on the contact area of nylon sleeve by dowels of metal bushing. Mathematical description of the offered hypothesis is given.

Pages 153-161

The authors investigated potential flow in a cylindrical coordinate frame, which is induced by two features situated in infinite space filled with ideal (nonviscous) fluid. The discharge is a circle situated on infinite impenetrable cylinder and an infinite vortex line coincident with the cylinder axis. The discharge - circle creates meridional potential liquid flow, and the vortex line creates potential rotation of fluid around the cylinder. The total motion of fluid is special. The function of velocities potential is presented as a sum of two functions, one of which defines meridional flow, and the second - liquid rotation, the analytic expression of which is known. There is no analytic dependence for the potential function of the velocities of the observed discharge - circle and we yet fail to get it. That’s why the authors used a new approach to investigation of potential flows, which have no analytic expression of potential function, developed by I.E. Mikhaylov. It is based on kinematic similitude of two flows, for one of which the potential function is known. This function is basic and the analytical dependence of the unknown function of velocity potentials is presented as a product of basic function and theoretically justified coefficient -velocity corrective, which correlates with the velocity of unknown motion. The authors obtained analytic dependencies for velocity correctives, velocity components, stream surfaces and their meridian sections, fluid lines projections of the total flow on the horizontal plane, which are spiral-shaped. The investigation has finished appearance and is ready for engineering solution. It is stated, that the flow formed by vortex discharge - circle well corresponds to liquid motion in spiral turbine cases and may be used for their calculation.
