ONHISTORY OF BUILDING OF WOODENSHELLSAND<неи THEIROPPORTUNITIESATPRESENTANDINTHEFUTURE
Resumo
The history of building of wooden shellsnumbers several centuries. It begins after hipped roofs of tower buildings and church domes. Principally new structures of large-span wooden shells appeared in the 1920th. After this period, the history of building of wooden shells is researched in the manuscript. Review of the ways of development of modern architecture of wooden structures which is directed both towards the creation of the sole unique objects and towards the forming of standard structures, is the aim of this manuscript.

POLYHEDRONIC BOX TYPE SURFACES AND THEIR APPLICATION TO ARCHITECTURE
Resumo
The article studies different types of so-called «box type» surfaces with cross sections in the form of a polyhedron, and also presents examples and perspectives of their use in modern architecture.

MOISTURE ELASTICITY OF INHOMOGENEOUS THICK-WALLED HOLLOW BALL UNDER NONSTATIONARY HUMIDITY CONDITIONS
Resumo
There is presented a solution of the problem of centrally symmetric unsteady moisture transfer in a hollow spherical array, modeling part of ground mass, with the propagation of the moisture from the inner surface to periphery. At the second stage is solved quasistationary problem of moisture elasticity for heterogeneous body because of uneven changing the deformation characteristics of the soil by saturated it with moisture. The term “moisture elasticity” is used by analogy with the term thermo-elasticity since the presence of moisture in the material induce forced deformations which is similar to the temperature deformations and problems of heat and mass transfer use the same mathematics.

ON PROBLEM OF STABILITY ANALYSIS OF AN EPITHROCHOIDAL SHELL
Resumo
Возможные виды потери устойчивости в эпитроидальных оболочках могут быть разбиты на две категории: потеря устойчивости в сжато-изогнутых оболочках и потеря устойчивости в сжатых оболочках. Эти вопросы изучаются в статье

RESEARCH KINEMATIC AND DEFORMATION PARAMETERS OF SINK RAWING
Resumo
Determination of thickness of a wall of a pipe at sink rowing happens generally to use of empirical and semi-empirical dependences. The offered theory allows to define level of the deformations operating at forming, and mathematically to prove change of thickness of de- formable preparation

THE AERODYNAMIC DAMPING WHEN VIBRATION OF CABLE SYSTEMS
Resumo
He work shows that wind flow exerts a dampening effect on the wavering guyed system and provides analytical and numerical solutions, demonstrating the degree of damping. It is shown that the damping of oscillations will be obtained in a natural way if wind pressure is taken to be proportional to the square of the relative velocity of the air and points of moving design

ALGORITHMS FOR THE RESEARCH OF STRENGTH AND STABILITY OF REINFORCED ORTHOTROPIC SHELLS
Resumo
The paper describes several algorithms based on the method of parameter continuation for thin-walled orthotropic shells. The basis of the study incorporated a mathematical model that takes into account the geometric nonlinearity, lateral shifts, as well as shear and torsional stiffness of the reinforcement. Showing results for several variants of panels conical shells of carbon fiber. A comparison with similar isotropic structures of steel is presented.

NON-LINEAR HEREDITARY CREEP THEORY
Resumo
The analysis of rules of the creep theory for materials with essentially non-linear momen- tary behavior (concrete, stone masonry, wood, aluminum, polymer) is researched. Non-linear creep equations are got as well as equations connecting full and instantaneous deformations. The equations for traditional creep measure are got both in integral and differential forms.

THE FINITE DIFFERENCE METHOD IN PAVEMENTS RESEARCH WITH REAL TRANSPORT LOADING
Resumo
The finite differences method application model to calculation of pavements dynamic characteristics is offered. The recurrence relationsallow establishing amplitude-time and am- plitude-frequency characteristics taking into account viscoelastic material properties. Results of computing experiment are received at varied values of physic mechanical characteristics.

HISTORY OF THE TOPOGRAPHY IN BENIN: THE OUTSETS OF THE TOPOGRAPHY AND ITS REALIZATIONS IN DAHOMEY (1850 to 1955)
Resumo
The origins of the topography in Benin, (ex French Colony of Dahomey) result from the necessity to the future colonist to know in detail the territory which he desires to establish his military strategy of conquest. Then, the topography came in Dahomey by the missionaries to assist at first the campaign and the military expedition of Danhomey and then to assure the development, the reorganization and the territorial management of the new colony at the be- ginning of 1900s. So the Department of Topography, created for that purpose and animated periodically by different French land surveyors took an important part in the plan of towns and the construction of infrastructures.
