The investigation of soil is a particularly important stage of structural design. Cone penetration tests (CPTs) are the most common soil investigation techniques. The results of these tests provide information about the values of cone resistance (qc) and sleeve friction (fs), which correspond to depth. Previous studies have shown that the ratio of sleeve friction to cone resistance depends on the particle size distribution in soil and its use for soil classification. Unfortunately, as an analysis of the literature shows, there is no such classification for coarse-grained soils. This paper presents statistically significant differences in the ratio of fs to qc in coarse-grained soils. Based on the research performed, the proposed coefficients depend on the classification of coarse-grained soils with respect to the size of the soil particles. The data investigated were obtained from study reports on 35 sites (5934 tests) at which the main type of soil was coarse-grained and contained different sizes of particles. Following a statistical analysis, five groups of tested coarse-grained soils, silty fine sand, clayey fine sand, fine sand, medium sand and gravelly coarse sand together with gravel, are derived. The analysed data show statistically significant differences in the ratio of fs to qc considering this particular type of soil. A ratio of fs to qc with a probability of 95% is proposed for sandy soils. The values for silty fine sand, clayey fine sand, fine sand, medium sand and gravelly coarse sand mixed with gravel are 0.009459, 0.010982, 0.009268, 0.008001 and 0.006741, respectively. A linear relationship between the fs and qc indexes is also suggested. Full article

This study aimed to evaluate the static response of prestressed reinforced concrete beams strengthened in their flexure and shear properties using different strengthening techniques, steel plates, and externally bonded woven carbon fiber fabric (WCFF). The experimental work involved testing twenty large-scale prestressed reinforced concrete beams with a length of 3000 mm, and cross-sections measuring 400 mm in height and 200 mm in breadth were cast in the factory and tested in the laboratory. Four beams without prestressing served as the reference beams; two unbonded pre-tensioned beams served as the control beams, and the remaining fourteen beams were strengthened with steel plates and externally bonded woven carbon fiber fabric (WCFF). Eight of the beams were strengthened with 4 mm thick steel plates and tested under a monotonically increasing load with manual readings recorded. The remaining six beams were strengthened with 0.5 mm thick WCFF and tested under a monotonically increasing load with manual readings recorded. The variables considered included the strengthening techniques (FRP composite sheets, steel plates), the types of strengthening (slices, U-shaped), and the flexural and shear capacities of the strengthened beams. All the implemented strengthening techniques yielded enhancements in both the flexural and shear strength outcomes of the beams compared to their respective controls. The most significant increase in load capacity, whether in terms of ultimate load or first crack load, for the prestressed concrete beams’ flexure properties occurred when strengthening with U-shaped steel plates. Additionally, the greatest reduction in deflection at the point of reaching the maximum load for the prestressed concrete beams, in terms of their flexure properties, was observed when strengthening with U-shaped steel plates. Similarly, the maximum load increase for the prestressed concrete beams, in terms of their shear properties, was achieved through strengthening with U-shaped woven carbon fiber fabric wrapping. Furthermore, a finite element model was created to simulate various experimental specimens. The finite element model’s results exhibited harmony with the experimental results, affirming the efficacy of the presented finite element model. Full article

It is a common practice to construct new buildings in the close vicinity of existing buildings. New buildings require deep excavations, which cause non-uniform displacement of the ground, causing a negative impact on the safety and technical conditions of adjacent buildings, including masonry buildings. The fundamental condition to verify structural safety is the knowledge of impacts and the load-bearing capacity of non-strengthened or strengthened structures. Safety is provided via strengthening the structure against deformations related to the ground displacement or by reducing non-uniform displacements of the building structure. This paper focuses on strengthening the ground and underground parts of masonry buildings. It also describes general requirements for providing safety of buildings according to the standard Eurokode 0 and the simplified method for protecting building structures with the use of steel tie rods. Based on the design methods for masonry structures specified in Eurocode 6 and the know-how of the authors in the field of protecting buildings in mining areas, the original method was proposed to determine the required area of reinforcement in the form of steel rods. Also, the original methods were introduced to verify ULS for inclined walls primarily under vertical load and shearing of pillars between openings. In addition to these analytical methods, this paper also illustrates methods for strengthening the ground and underground parts of masonry buildings. Presented in this paper, original solutions used to determine the strengthening of masonry structures and original models used to verify ULS for deflected walls primarily under vertical load can be directly employed in the design practice. The standard criteria were applied and the effects of building deflections, which are not specified in Eurocode 6, were considered. Full article

Title: Design of high-performance concrete mixtures for additive manufacturing technologies
Authors: Oldrich Sucharda; Radoslav Gandel; Petr Cmiel; Jan Jerabek; Vlastimil Bilek
Affiliation: VSB – Technical University of Ostrava, Faculty of Civil Engineering, Department of Building Materials and Diagnostics of Structures, Ludvíka Podéště 1875/17, 708 00 Ostrava-Poruba, Czech Republic
Abstract: The presented experimental program focuses on the design of high-performance concrete dry mixtures, which could find application in additive manufacturing technologies in 3D printing. The research is specifically aimed on the basic strength-mechanical properties (compressive strength, tensile splitting strength, and flexural strength) and durability properties (frost resistance, resistance to water and defrosting chemicals) of hardened mixtures with partial insight into the rheology of fresh mixtures (consistency by slump-flow test). Additionally, selected mixtures in the form of specimens in combination with concrete reinforcement were tested for load-bearing capacity. The reference mixture with two liquid plasticizers, first based on polycarboxylate and polyphosphonate and the second one based on polyether carboxylate, was modified using the powdered plasticizer, based on polymerization product Glycol, to create a dry mixture and compared with developed mixtures in the above-mentioned properties. The presented work provides an overview of the compared characteristics, which will serve as a basis for future research in the development of additive manufacturing technologies.

Title: Mechanical Properties, Microstructure and Reinforced Concrete Beams with Alternative Binder
Authors: Zuzana Marcalikova; Jan Jerabek; Radoslav Gandel; Roman Gabor; Vlastimil Bílek; Oldrich Sucharda
Affiliation: Faculty of Civil Engineering, Department of Building Materials and Diagnostics of Structures, VSB - Technical University of Ostrava, Ludvíka Podéště 1875/17, 708 00 Ostrava-Poruba, Czech Republic
Abstract: Arguably the most important element in sustainability of concrete development is discovery of optimal sustainable binder. Great interest is displayed in alkali-activated materials, which possess good characteristic and could be considered as environmentally friendly, because of usage of secondary materials in its production. Aim of this experiment was determination of the mechanical properties of three different mixtures based on the same ingredients. The first mixture was a referential one in which the binder was Portland cement. In the second mix, cement was replaced, and a finely ground blast furnace slag was used instead. In the third mixture, part of the aggregate was replaced with light artificial aggregate. The experiment focused on testing and mutual comparison, firstly of processability of the fresh mixture and then of mechanical characteristics, which include strength in compression, split tensile strength or static modulus of elasticity with addition of tests of resistance to high temperatures. The tested structural elements were reinforced concrete beams without shear reinforcement, while three levels of reinforcement were used for each variant of the mixture and were tested with a three-point bend test. The last test was the determination of the tear strength of the surface layer of the beams.
