Prospects of Development of Regulation Base of High-Rise Construction in Russia Problems of the formation of the regulation-technical base of high-rise construction and the nearest prospects of its development are considered. In the situation, when there are completely no official regulation documents, requirements of which are included in the list of required for the application or in the evidence base necessary for designing, the development of the first code of rules “High-rise buildings and complexes” which will be a basic document, was a very important step. At that, for its development it is planned to develop new documents covering specific issues of fire and complex safety, as well as other problem directions. This makes it possible to improve the safety of objects under construction, simplify their designing, excluding in many cases the need for developing special technical conditions and to provide the development of high-rise construction as a whole. At present, it is especially actual to concretize the further prospects of the development of the regulation base of high-rise construction, this is possible on the basis of experience exchange of organizations concerned and this publication aims to contribute to this.

Keywords: high-rise buildings, high-rise complexes, regulation base of high-rise construction, architecture of high-rise buildings, structures of high-rise buildings, design of high-rise buildings.

The Use of Seismic Isolating Devices in Buildings with Underground Spaces The present development of megapolises is impossible without development of underground spaces which can be used for auto-parking, location of transport hubs, engineering communications and other purposes. At that, many cities are situated in the zones of high seismic activity which significantly influence on the behavior of buildings with underground spaces. One of the measures to increase the seismic resistance of such building objects is introduction of seismic isolation supports between aboveground and underground structures. Results of the study of the impact of such elements on the seismic resistance of buildings prove the efficiency of such seismic protection. The use of these supports makes it possible to reduce seismic loads by two and more times.

Keywords: buildings with underground spaces, seismic effects, seismic isolation supports.

Simulation of Functional Structures of High-Rise Buildings Issues of the simulation of high-rise buildings are covered. High-rise buildings are a complex multilevel system consisting of various functional structures subordinated to three main types of livelihood – housing, work, and rest. To provide these types of activity, high-rise buildings include type-forming, additional, and operational-technical structures on the basis of which functional purposes of the building are determined. When developing the architecture of the high-rise building, natural-climatic conditions, wind loads especially, are of great importance. Equally important is the chosen structural scheme ensuring the safety of operation of the building. The simulation of vertical zoning of the high-rise building provides the correct location of functional structures, their interaction and interconnection that improves operational qualities of the building.

Keywords: functional structure, external and internal factors, informational, dynamic, static models, simulation stages.

Study of Effect of a Casing of Bearing Columns The actuality of introduction of bearing metal-concrete (tube-reinforced concrete) columns in the course of which operation an effect of the casing reveals itself is presented. Processes taking place at different stages of loading of metal-concrete columns of two types are considered: the load is transmitted to the whole cross-section of the column, the load is transmitted to the concrete core only, the metal casing isn’t loaded. Results of the medium-scale experiment carried out to confirm the theoretical background with six series of models of bearing columns of different types, and main conclusions formulated on the basis of experimental data are presented. The choice of the most prospective type of metal-concrete column, which, at out-of-limit loads, reveals in full the effect of casing and pronounced plastic character of destruction and also the high residual bearing capacity is observed (after application of out-of-limit loads to the structure, it flattened without buckling) is substantiated.

Keywords: tube-reinforced concrete, casing effect, buckling, metal-concrete column, loading.

Forecast of Long Settlement of a High-Rise Building Footing with the Use of Analytical Diagrams of Soils Deformation When designing high-rise buildings, it is necessary to account the influence of stages of their erection, this is the sequence of footing loading, on the change in physical-mechanical properties of footing soils. The calculation of deformations of foundation bases is made with due regard for the change in soils properties comparing with the initial (natural) state. On the basis of the results of experimental studies, the authors substantiate the necessity for introducing the new parameter which makes it possible to characterize the mechanical condition of the soil at any stage of loading and can be used for creating calculation models. An analytical diagram of soil deformation in coordinates «σ1–ε1» for triaxial compression (where σ1 – vertical stresses (deviator), ε1 – linear deformations under the triaxial compression) is adopted as this parameter. The procedure for constructing transformed diagrams of the soil state under the long performance triaxial loading is described. The procedure obtained was approbated when calculating deformations of the foundation base of the high-rise building with due regard for the influence of staging of construction and rheological properties of soils on the change in the base rigidity and, as a result, on the redistribution of stresses among separate elements of the system “subsoil –foundation – above-ground part of the building”.

Keywords: long regime triaxial loading, analytical diagram of soil deformation, coefficient of subgrade resistance, settlement calculation, high-rise building.

New Structural Solution for Reinforcing Cage of Junction Zones of Reinforced Concrete Slabs with the Use of Sheet Products A new structural solution of junction zones of resting of monolithic reinforced concrete floor slabs on columns and columns on foundation slabs in buildings of various purposes is presented. As an alternative to bar spatial reinforcement frames installed in zones of slabs pushing, it is proposed to use combined frames with the use of bar and sheet reinforcements. Experimental studies of the strength of reinforced concrete slabs with sizes of of 300300 cm and a thickness of 50 cm to the action of a local transverse force have been conducted. It is shown that the scheme of sheet reinforcement of support zones of monolithic reinforced concrete slabs proposed instead of the used standard structural solutions of reinforcement of these zones with the use of transverse reinforcement cages makes it possible to eliminate the appearance of dangerous forced cracks in slabs, to ensure the operation of concrete in shear and thus considerably increase their bearing capacity in pushing zones. On the basis of experimental results, it is noted that at all stages of destruction until the destruction itself, the sheet reinforcement is deformed together with the concrete. At that the destruction of samples takes place without the separation of structures for separate fragments as it is when testing slabs reinforced with transverse reinforcement only for pushing. The proposed structural solution of reinforcement of the junction zone of floor slabs and foundation slabs at the section of columns resting was used at concrete objects constructed in Moscow and St. Petersburg and demonstrated their high workability and reliability as well as economic efficiency.

Keywords: foundation slabs, floor slabs, sheet reinforcement, pushing, concrete shear.

Research in Compression Ratio of Soil in Field and Laboratory Conditions during Reconstruction of Main Oil Pipeline This work is devoted to study the degree of soil compaction during welding and installation works on the main pipeline Anzhero-Sudzhensk–Krasnoyarsk. The research was conducted directly at the site of the reconstructed section of the pipeline (in the field) by using the dynamic sensing of soil and the standard method according to GOST in the laboratory. The investigation of the degree of soil consolidation were conducted when arranging ground prisms for the layout of pipe products, ground prisms for the welding of the pipeline, when backfilling the laid pipeline, arranging barns and crossings. On the basis of the conducted research, factors of soil compaction obtained by laboratory and operational methods under field conditions were established and compared. The data obtained makes it possible to assess its compliance with the design data.

Keywords: main oil pipeline, compression ratio of soil, ground prism, operational method, laboratory method.
