МЕХАНИЗМЫ ВЛИЯНИЯ КАРБОНАТОСОДЕРЖАЩЕГО НАПОЛНИТЕЛЯ НА ОСНОВНЫЕ СВОЙСТВА КЛАДОЧНЫХ РАСТВОРНЫХ СМЕСЕЙ И РАСТВОРОВ

Impact mechanism of a carbonate filling material on basic properties of masonry mortar mixes and solutions

Possibility of using raw sludge from water treatment in the capacity of carbonate filling material for masonry mortars is observed. With help of radio-photography, microscopic, granulometric analyses there are installed mechanismes of positive influence of a filling material on basic properties of masonry mortar mixes and solutions. Polynomial models of solution strength, delamination and water-retaining ability of mortar mixes are gained. Tests on brick masonry on cement slurry containing filling material are resulted, including strength and relative deformations.

Self-stressing CFST elements design

The calculation system of resistance of self-stressing CFST elements of round cross-section at axial compression is worked out. The algorithms of transition from initial value of the self-stress received at a stage of structural components manufacturing to a corresponding size in a stage-limit of the work which is necessary for the estimation of resistance are offered. Demanded (minimum and effective) values of elements of initial self-stress depending on mechanical properties of materials and geometrical pa-rameters of composite section are proved.

Modeling of resistance of RC-elements at action of tensile load

In article is presented the general engineering design procedure of crack width, received on the basis of experimentally-theoretical research of work of reinforced concrete elements at action of tension loading. Being based on studying of the mechanism of interaction and transfer of forces between reinforcement and tension concrete to authors of article it was possible: • to establish laws of formation and opening of cracks in reinforced concrete elements; • to formulate an analytical model of resistance of a reinforced concrete element to action of the tension loading, based on the complex approach to process of cracking, considering physical laws of deformation and interaction of materials, and on her basis to receive the equations describing dis-tributions of relative deformations of reinforcement and tension concrete on the length of an element. It has allowed to make quality assessment of the strain-stress state of the reinforcement and the tension concrete at different cracking stages; • to receive an analytical equation for definition of the length of the force transfer zone between the reinforcement and the tension concrete for the various bonding conditions defined by surface and diameter of reinforcement, and also strength of concrete; • to receive a relation connecting average crack width (wm) with relative deformations of reinforcement in section with a crack, geometrical para-metres of cross-section section of a reinforced-concrete element, strength characteristics of reinforcement and concrete and in the predicted dis-tance between cracks.

Design procedure of survivability of structural construction of system «BSTU»

The design procedure of survivability of metal structural designs of system "BSTU", based on calculation of elements outside of elastic work is de-veloped up to loss of stability of the compressed cores and ruptures of the stretched cores and redistribution of efforts in system in process after design works of a construction. Verification of settlement model of survivability of structural designs system "BSTU" by results of tests of a natural fragment which has allowed to establish the basic stages of survivability: 1 – work of a design within design loads, 2 – work of a design before occurrence of the first plastic hinges in elements, 3 – a stage of accumulation of damages to a design, 4 – a stage of dynamic damage of a design, 5 – a stage of destruction of a design. Construction of the diagramme of deformation of various constructive forms of structural designs of system "BSTU" such as a dome of a covering of a building of NOK RB and a structural plate of a covering of a scene in Hojniki who give the chance to describe process of accumulation of damages of constructions and to define levels of a stock of bearing ability for their all stages design loading and after design loading.

Experimental researches of work of the continuous footing on the convex earth foundation

In this article results of laboratory researches of model of base slabs on a flat earth foundation and the base in the form of a trapeze are stated. It is determined that a bending deflection of a model is slab on the flat base much greater of the deflection on the base in the form of a trapeze. Therefore application of the bases in the form of a trapeze gives the chance to design more energy conserving structures of continuous footings.

About the doctrine urban planning and resettlement-strategic planning of cities

The paper concerns a formulation of proposals for the development of the doctrine of urban planning and resettlement (strategic urban planning). The author gives an analysis of the current state of the environment and the necessity of a creative approach to urban development and person devel-opment at the time of contemporary environmental and social problems of the country and global challenges. The main strategic goal of the doctrine is urban development based on the concept of biosphere compatibility for towns and residential settlements, which can develop a person.

The economic rationale of options works projects for the production

This paper presents a method for comparing options for organizational decisions of schedules, developed in the projects of the works. This ap-proach includes the registration of an integral economic effect of reducing the duration of construction for both the investor and the contractor. For the investor it is taken to attention the reduction in the discounted cost of the construction phase of the object and the economic effect achieved in the area of operation of the facility from its operations in the period of early commissioning. For the contractor it is taken to attention the reduction in the quasi-permanent costs and reducing the loss of attraction of fixed assets of a construction company.

Historic archive and bibliographic researches for historical objects restoration (example of catholic monasteries of Belarus in XVII–XVIII centuries)

Exact historical data on architecture of Catholic monasteries of Belarus are necessary for use of results of research work not only at restoration, but also at erection of new objects in the new town-planning environment. The purpose of given article to fill knowledge on researches of Catholic monastic complexes and to define the works having historical or practical interest for researchers and restorers of stone cult buildings. Today there is a set of books and articles on various questions of restoration, including work on stories of restoration with the extensive bibliography. The restoration history, restoration works, their features and problems are considered only for the general systematization of the literature, these questions are a subject for independent and extensive researches. As a whole we will notice that for development of concrete methods of restoration of stone cult constructions it is necessary to consider objects of such class in many directions where the scientific base includes the historical inquiry on a monument with historical archival and bibliographic research

Tradition and Modernity in the construction of Orthodox churches

The provisions of article are consistent with the applicable laws of the Republic of Belarus on the Protection of Historical and Cultural Heritage, which provides for and requires a respect for its objects, regardless of the typological affiliation, category, level of significance. The traditional architectural features of the Orthodox religious structures are directly reflected in the appearance of modern churches. These build-ings and complexes – part of building towns and villages, they take their rightful place in the urban structure, often as high-rise accents. The task of rehabilitation and new construction of orthodox churches have national significance. Understanding and cooperation shown between the heads of state and members of the Synod of the Belarusian Orthodox Church. Large amounts of construction of new temples, reconstruction and rehabilitation of existing churches
