Precast-monolithic house-building in domestic and world practice is a significant part in the mass construction. We propose a relatively large number of designs of precast-monolithic buildings, as well as its individual elements. Despite this, we cannot say that found the most effective constructive solutions able to satisfy the requirements of consumers (future residents) and builders. On this basis, we developed quite effective, from the point of view of construction and further operation, a constructive solution of light weight precast-monolithic overlap. Some features offered are overlapping: smaller mass, compared with beams of heavy concrete; increased heat and sound insulation properties; optimal use of the structural properties of heavy and light precast monolithic concrete and longitudinal reinforcement, depending on the stage of construction. The author has carried out in this article the results of numerical studies the proposed design of precast-monolithic overlap, confirming its compliance with the requirements of 1st and 2nd group of limit States.

Currently, great attention is paid to the choice of optimal and rational design and construction solutions for individual structures and buildings in general. In the process of design not only constructive solution of an element is important, but also its location in the design scheme of the building. It is known that the correct consideration of the elements interaction in the design scheme contributes significantly to the rigidity and strength of multi-storey buildings.Slabs are involved in bending and shear and act like keys between the vertical elements. In order to reduce shear deformations and enhance overall stability of the building it is possible to increase the size of the keys, that means, to increase the height of a slab. In is necessary to determine the area that has the most significant impact on the rigidity and stability of the frame.For deciding that issue a computer model of 25-storey building was built. Settlement scheme was used to estimate the strength, deformability and stability of the frame.Basing on the models stability assessment it is suggested that the most efficient design solution is the floor slabs strengthening in the middle tier of the building by 0.4-0.5 heights of the building.

Modern intensive development of precast-cast-in-place construction has led to creation of a wide range of various constructive systems of buildings during the last 100 years. They allow constructing buildings with best account of the requirements of functionality, architectural expressiveness, production possibilities of construction companies, etc. However in spite of this development both precast and cast-in-place housing construction has its peculiarities, positive and negative ones. The constructive systems of precast monolithic buildings existing at the moment are based on the required mutual deformation of prefabricated reinforced and cast iron reinforced concrete at the stage of a building construction and at the stage of its use as well. Having refused from this rule, the authors of this article have introduced a constructive system of a precast monolithic building able to bear loads, developing at the stage of erection (due to completion of a precast frame) and at the stage of use (due to completion of a precast monolithic frame). The offered construction of a precast monolithic building frame allows efficiently using the advantages of precast and cast-in-place construction minimizing their disadvantages and it also fully corresponds to the obligatory requirements to buildings. The corresponding patents are obtained.

Precast-monolithic construction is becoming an increasingly popular form of housing. The wide distribution of this type of construction is explained by the possibility to successfully combine the advantages of precast and monolithic construction, at the same time reducing their disadvantages. Though there is a significant lack of data, including experimental data, for objective assessment of the stress-strain state of precast-monolithic floor structures. In order to investigate the structural reliability of the bolt joint of a bearer with a column in a precast-monolithic building a series of experimental investigations were carried out in the laboratory of testing the building structures of the Siberian Federal University.One of the main conclusions is that the bolt joint of a bearer with a column is characterized by sufficient rigidity, crack resistance and bearing capacity. The results of the given work have proved the data obtained in previously conducted investigations on a fragment of a precast-monolithic ceiling.

The contemporary precast-cast-in-place housing construction has become widely used on the territory of Russia. A great amount of big construction companies begin using the technology of precast and cast-in-place housing construction as the main one. This fact is proving the convenience of reinforced precast and cast-in-place concrete for the buildings of various functions in the climatic conditions of our country. Though there is a lack of investigations of such constructions though they are increasingly developing. Due to the lack of experimental research data existing at the moment, which allow estimating deformed condition of precast-cast-in-place constructions of slabs objectively, experimental research of hollow slab longitudinal beam with precast-cast-in-place and cast-in-place joist was carried out by the authors. The results of the given work prove the data previously obtained by the authors in their experiments using a fragment of precast-cast-in-place slab.

At the present moment in Russia the construction of precast and cast-in-place frame buildings are widely spread in Russia. This technology is the most advanced because of the possibility of maximally efficient simultaneous use of the advantages of precast and monolithic housing construction with minimizing their disadvantages. At the same time the volume of the scientific researches on stress-strain state of cast-in-place and precast constructions is not enough to objectively evaluate the bearing capacity, rigidity and crack-resistance of such buildings. Cast-in-place and precast construction covers a considerable part in large-scale construction, but despite this, there is a great variety of gaps in the understanding of such construction performance. Reasoning from this fact, numerical and experimental research has been carried out on studying of the performance of longitudinal beam joint to column with a column in slab cast over precast joists.

At the present time reinforced concrete is the main construction material in civil and industrial construction. Cast-in-place and precast construction is gradually becoming a more widespread type of house-building, but still there is a lack of data, including experimental data, which allows evaluating the stress and strain state of a construction of a slab cast over precast joists. Experimental research of stress and strain state of slab cast over precast joists with prestressed reinforcement was carried out. An experimental model of a fragment of a hybrid precast/cast-in-place building was produced and tested (reduction scale 1:6). The experimental investigations of slab cast over precast joists with prestressed reinforcement proved that the construction solution of the framework offered in the previous works of the authors possess good stiffness, crack-resistance and bearing capacity. It well fits for constructing the slabs of long spans in residential and public buildings.

Subject: an analytical solution to the problem of interaction of the pile and the raft plate with the surrounding soil taking into account the possibility of expansion of the pile’s shaft is given. Closed solutions are obtained for determination of stresses in the pile’s shaft and in the soil under the raft plate. We take into account the effect of prestress of the base after compaction on formation of stress-strain state during construction and operation of structures. These solutions are relevant for compaction piles made of crushed stone or soil-cement piles whose stiffness is comparable with the stiffness of the surrounding soil. Research objectives: determination of the average strength and deformation parameters of weak soils subjected to transformation using the piles of finite stiffness made of loose gravel material and soil-cement material; comparative analysis of the obtained results with the data of in situ tests on a construction site. Materials and methods: when solving the problem of interaction between the pile and the surrounding soil with the expansion of pile’s shaft, analytical solutions based on well-known expressions of classical soil mechanics and solid mechanics are used. Experimental studies were carried out on a certified laboratory equipment and with the help of field methods regulated by the existing design codes. Results: the presented technique of improving mechanical parameters of soils and the method of their calculation in the transformed foundation allow us to determine the average characteristics of strength and deformability of the entire foundation. These techniques are necessary for analysis of the transformed foundation by two types of limit states in the process of designing the structure by analytical and numerical methods. Conclusions: the resulting dependencies and the proposed techniques for designing reinforcement of the base with the help of pile-drains are used on real construction sites. We present the results of large-scale tests at the experimental site for construction of a large energy facility in Russia as well as at the housing construction site in the Central region of the Russian Federation.
