Abstract:

Fire resistance of load-bearing wooden structures is evaluated by the charring of surface layers of wooden bearing elements. The degree of resistance is determined by the onset and course of charring; these basic parameters are affected by the cover structure as well as by cavity fillers between the individual bearing elements. This article focuses on analysing the structure of fire protection covers based on gypsum boards, namely gypsum plasterboards and gypsum fibreboards. The foundation for the current analysis, based on the ignition temperature of the load-bearing timber element under the

In Part 1, a computational method was described for predicting the performance of pivoted pad thrust bearings. In this second part, computed results are compared with experimental data. Three test cases are considered, which cover the range of bearing sizes normally encountered in practice, from a 150 mm diameter laboratory scale experiment through the main propulsion thrust bearings of a destroyer to a 3 m diameter bearing. Generally good agreement is obtained for both temperatures and film thicknesses.

Results demonstrate that cover plates improve load-bearing capacity and ductility by relocating plastic hinges outward from joint regions.

Plant survival, bloom response and fruit yield following fall application of a plastic row cover, plastic row cover covered with barley straw, conventional straw, and no cover were compared for two strawberry cultivars, Fragaria × ananassa Duch. Bounty and Hecker. Response was highly dependent on weather conditions. Plastic row cover + barley straw provided the best protection in winters with below-normal temperatures and low snowfall, resulting in the highest yields. Plastic row cover advanced blooming dates of both cultivars by at least 6 d over conventional straw mulch. With proper protecti

Abstract:

Abstract It is challenging to test the displacement of distribution lines under ice-cover conditions because of the complexities involved in the measurement and environment setup and the high associated costs. In this paper, the wire type and span distance of the distribution line are determined based on the line’s operating parameters, and the suspended catenary’s initial shape is calculated. A finite element analysis model of the distribution line under ice-loading conditions is established by using simulation software. The model simulates the effects of self-weight load, ice load, wind load

Abstract:

In the Transcarpathian Foredeep, the foundation rocks are not exposed on the day surface. They are available for study only based on the results of drilling in the post-war period or geophysical research. Over the entire long period of time, two hundred and fifty wells were drilled in the Transcarpathian Foredeep on twenty-two structures, with a total area of more than two hundred thousand meters. The deep drilling of one hundred and seventy thousand meters (about seventy wells) was carried out on ten structures. Five gas fields have been discovered within the foredeep.

Abstract:

While conducting exploration surveys for new hydrocarbon fields in oil-gas bearing basins of the world, the data on the mud volcanoes in the area and their explosion is widely used. As the stage of initial activity of mud volcanoes, the source of generation, the product of explosion etc. are associated with the deep layers (7–8 km) of the Earth, this process is an essential source of information for exploration surveys. One of the original aspects of the South Caspian basin is the great amount of mud volcanoes. The study of the composition of gas masses released into the atmosphere as a result

Four transverse bending tests and four longitudinal bending tests on steel–UHPC composite plates and steel–UHPC composite beams were conducted, respectively.

Carbonate rocks cover one fifth of the Earth’s sedimentary cover, having great economic significance and bearing important information about the mechanisms and settings of their formation. Research into carbonate rocks allows not only the settings of ancient epochs to be reconstructed, but also to the evolution of those settings to be established. Peer-reviewed textbooks are a good source of learning materials for university students investigating the origin and specifics of these rocks.

Additionally, to prevent the splitting of the concrete, hanging U-shaped hook upon textiles was also experimentally studied. The experiment results indicate that sticking sand on epoxy resin-impregnated textile and reduced cover thickness are helpful to improve the mechanical performance of the component; the textile with 10mm×10mm mesh size is superior than that with 20mm×20mm mesh size regardless of in the respect of enhancing the b

Introduction. The article is focused on evaluating the stress-strain state of nonreinforced arch cover structures made of thin-walled cold-formed profiles and arch cover structures reinforced by arch frames made of triangular trusses and girders. The relevance of the study is backed by the need to reinforce arch covers in the event that the design area of operation of a structure is different from the actual area of operation, which is confirmed by the recent cases of collapse of these structures. To reduce the labour input into simulation, the authors suggest a 3D modelling methodology presen

The need of concrete structures restoration in order to ensure their fire resistance can, in engineering practice, occur for reasons of damage to the structure by fire (spalling of concrete cover layer) or by the failure to cover the load-bearing structure during construction. The paper is devoted to the evaluation of the structure cover of the evaluated structure, the determination of temperature distribution in the structure with consideration to the choice of probable fire scenario, subsequent determination of critical temperature of the structure and the optimization of possible methods of

Abstract. This work uses sandbox analog models to analyze the formation and subsequent inversion of a decoupled extensional system comprised of two segmented half-grabens separated by a diffuse accommodation zone with thick early syn-rift salt. The segmented half-grabens strike perpendicular to the direction of extension and subsequent shortening. Rifting first created a basement topography that was infilled by model salt, followed by a second phase of extension and sedimentation, followed afterwards by inversion. During the second phase of extension, syn-rift syncline minibasins developed abo

Abstract:

Rolling-element bearings are simple machine elements of great utility used both in simple commercial devices as in complex engineering mechanisms. Because of being a very popular machine element, there is a lot of literature on the subject. With regard to the behavior of internal loading distribution, elastic deformations at point or line contacts, and geometric parameters under loading, although there are many works describing the parameters variation models, few works show such variations in practice, even under simple static loadings. In an attempt to cover this gap some studies are being d

Abstract:

Vibration signals acquired from bearing have been found to demonstrate complicated nonlinear characteristics in literature. Fractal geometry theory has provided effective tools such as fractal dimension for characterizing the vibration signals in bearing faults detection. However, most of the natural signals are not critical self-similar fractals; the assumption of a constant fractal dimension at all scales may not be true. Motivated by this fact, this work explores the application of the multi-scale fractal dimensions (MFDs) based on morphological cover (MC) technique for bearing fault diagno
