ALEKSANDROV A.S.
Abstract
The physical model of plastic deformations - time span and quantity of loads is presented. The process of accumulation of plastic deformations has inherited nature under multiple actions. The integral expression for the determination of plastic deformation caused by multiple force actions limited by Bolzman and Walter theory was derived and solved.

Abstract
Analysis of joint motion of building structure and crashing missile impacting it is described. The missiles of this kind may be generated by various natural and man induced events. Equations of motion are derived. Example of their application to the problem of successive perforation of several walls by crushing missile is given. It demonstrates that the methodology permits to take into account more accurately distribution of the missile kinetic energy between itself crashing and impacted building structure deformation. The methodology described may be used for safety analysis of nuclear power plants, civil defense and so on structures subjected to destructible large kinetic energy missiles impacts.

Abstract
The case of a throat crack in section of a road covering with partially contacting faces is considered. It is considered, that under action of external loading (cave-in of a wheel in a rough surface of a covering) in a zone of compressing stresses there is a partial closing faces of a crack.

Abstract
In the article, the stability of systems with finite of degrees of freedom is considered at the determined and stochastic action on the example of a suspension bridge. Calculations are executed on two models: the first one describes oscillations of a rigidity beam of the bridge by system of two partial differential equation and the second describes the same oscillations with help of FEM. Influence of parameters of the stochastic excitation on the value of the critical parameter is investigated.

KOLESNIKOV A.O., POPOV V.N.
Abstract
The expressions to define the parameters of stiffness and damping of the foundation with a deepened pile-cap based on a wave model are offered. For each kind of vibrations, dynamic parameters are defined, with due account to the interaction of a pile-cap with ground. A principle of superposition via summing up corresponding dynamic parameters of pile-cap and piles are used.

Abstract
The paper presents results of research on reinforced-concrete flat slabs and basic aspects of their construction technology. In practice of civil construction precast, precast and cast-in-situ, and total cast-in-situ slabs apply. The authors have been developed a new method of design of flat slabs and the reinforcing scheme which allows low cost of construction and raise a load-carrying capacity of conjunction knot of a slab with a column. This new method can be applied for designing of large-span slabs of 6-12 m and more with a thickness of 180-250 mm.
