The results of experimental studies of the strength of inclined sections of bent reinforced concrete elements with fiber-reinforced plastics are presented. Comparative data have been obtained on the use of new types of fiber-reinforced plastics for reinforcing reinforced concrete structures. Experimental studies have been obtained on the value taken into account in the ...

The results of experimental studies of the stress-strain state of reinforced concrete three-dimensional blocks under the action of vertical loads are presented. Information is given on the distribution of deformations, the formation and opening of cracks, horizontal displacements, strength and nature of destruction, and the influence of the type of concrete. Proposals are ...

The work determines the stress intensity factor (SIF) at the crack tip in bending reinforced concrete beams. The problem has been solved in a three-dimensional formulation using special elements that take into account peculiarities of the stress field at the crack tip. Calculations have been carried out for beams of rectangular cross-section with pure bending to obtain ...

New technologies in building and high-rise monitoring make it possible to track damage and defects in existing structures and infrastructures. The need for timely detection of defects in building structures using fiber optic sensors is increasingly prompting planners, builders and facility managers to use the capabilities of a powerful system such as DFOSS. In addition to the ...

The issues and examples of remote monitoring, methods of technological improvement on the example of bridge structures are considered. After the analysis of the problems and examples of deformation monitoring was carried out, the next stage of the development of a technique for technological improvement began. As the analysis showed, the big problem of GNSS is the distortion ...

Recent years demonstrated the widespread use of maturity sensors for monitoring structural elements of monolithic building frame resulting in the development of many instructions on their application, which does not apply to the monitoring of geotechnical structures. This paper presents potential use cases and setup methods of embedded maturity sensors. Proposed instructions ...

New socio-economic conditions of Kazakhstan in recent years, as well as increased requirements for the most efficient use of the territory of Astana and the cities of Northern Kazakhstan, have led to new design directions, where intensive construction of a large number of new residential buildings has begun. A prestigious home appeared in terms of comfort and location. ...

Non-destructive techniques (NDT) for on-site analysis of various structures such as historic buildings and monuments are gaining traction due to inherent limitations of conventional invasive methods requiring sample collection for often off-site assessment. This work will investigate current trends in non-invasive assessment of built structures of historic and/or cultural ...

Quasi-static problems with respect to the stress-strain state and a class of problems with respect to forced vibrations acting in plain and spatial nodes of a high-class mechanism with elastic links are considered, taking into account the model of friction forces in kinematic pairs under the action of vertical and horizontal concentrated forces in kinematic pairs. The ...

The article deals with geotechnical design of pile foundations, especially by static load tests and by calculation using numerical models. The results of comparison analysis of bearing capacities drilling displacement system (DDS) boring piles obtained by static load tests and by standard are presented in article, as well as results of compression test of surrounding soil ...
