This paper presents the results of static and dynamic tests of fiber-reinforced and unreinforced concrete samples under laboratory conditions. Concrete samples reinforced with steel and non steel fibers were tested. The dynamic tests were carried out on the stand by applying falling weight impacts on the concrete samples. The impact testing of samples included two stages of deformation: until the first defects appeared in the samples and until their complete destruction. The impact resistance of the samples was evaluated according to the energy input of the hammer with registration of the type, size and volume of the defects. It was revealed that the type of fibers has a different effect on the static and impact resistance of fiber concrete. Correlational dependencies used for predicting the strength and energy parameters of fiber concrete in their comparative evaluation have been obtained. It has been determined that the static strength and impact resistance of fiber concrete may not be identical, i.e., a high static strength in fiber concrete does not always provide a high impact resistance. The impact resistance of fiber concrete when tested before the first defects appear is always lower than when tested before complete failure.

“…Based on this, it is obvious that it is relevant to create a pile structure of such a form that would have the advantageous properties of both prismatic and pyramidal piles in an optimal combination [3][4][5][6][7]. Such driven piles include pyramidal-prismatic piles developed in the geotechnical laboratory of M. Kh.…”

The results of experiments carried out in the field with the use of large-scale models of reinforced concrete driven pyramidal - prismatic piles with different lengths of the pyramidal part are presented. The impact capacity of piles were evaluated of their bearing capacity to the action of indentation and horizontal static loads. It has been established that the driving of pyramidal-prismatic piles is accompanied by both large (by 1.10–1.60 times) and lower (by 8.0–37.0 %) energy consumption for their driving in comparison with conventional pris-matic and pyramidal piles. It was also revealed that under the action of a vertical indentation load, the bearing capacity of the pyramidal-prismatic piles is 1.09–1.48 times, and under the action of a horizontal static load, it is 1.17–1.80 times higher than that of a prismatic pile. It has been established that with an increase in the length of the pyramidal part of the test piles, there is an increase in their bearing capacity by 1.12–1.34 times. Formulas are proposed for determining the bearing capacity of pyramidal-prismatic piles. The research results serve as the basis for the development of recommendations for the calculation and design of pyramidal-prismatic piles.
