Sediment thickness in the Bay of Bengal and Andaman Sea compared with topography and geophysical settings by GMT

Data publikacji: 31 Dec 2020
Zakres stron: 13 - 21

Abstrakt

Abstract

The study presents an analysis of the sediment thickness compared with bathymetric and geophysical settings in the Bay of Bengal and Andaman Sea, Indian Ocean. It uses a combination of the high-resolution data: topographic GEBCO, satellite and marine gravity anomalies, EGM2008 geoid and GlobSed to visualize the correlation between relief, gravity and trends in continent-ocean sediment transport. The results include thematic maps and 3D model showing increased sediment thickness in the Bengal Fan (8,0 to 8,2 km) in NE direction with maximum in Ganges Fan (16,2 km), and southward decrease in the Andaman Sea from Irrawaddy river mouth (6-7 km) to the Strait of Malacca (1-2 km). All maps and 3D model have been plotted by Generic Mapping Tools (GMT) cartographic scripting toolset version 6.0.0.

Effects of Shear Lag in Steel Box Girders of a Crane Runway

Data publikacji: 31 Dec 2020
Zakres stron: 23 - 31

Abstrakt

Abstract

The term of shear lag is related to the discrepancies between the approximate theory of the bending of beams and their real behaviour. It refers to the increases of the bending stresses near the flange-to-web junctions and the corresponding decreases in the flange stresses away from these junctions. In the case of wide flanges of plated structures, shear lag caused by shear strains, which are neglected in the conventional theory, may be taken into account by a reduced flange width concentrated along the webs of the steel girders. In EN 1993-1-5, the concept of taking shear lag into account is based on effective width of the flange which is defined in order to have the same total normal force in the gross flange subjected to the real transverse stress distribution as the effective flange subjected to a uniform stress equal to the maximum stress of the real transverse distribution. Some aspects concerning the shear lag phenomenon and a working example for a box girder of a heavy crane runway to illustrate the determination of the shear lag effect are also presented.

Research on Improving the Welding Behaviour of Stainless Steels in the Field of Welded Constructions by Using Mechanical Vibrations

Data publikacji: 31 Dec 2020
Zakres stron: 63 - 70

Abstrakt

Abstract

This paper presents a research that has been done on two types of stainless steels, one of Spanish origin and the other of Romanian origin. Both Spanish and Romanian stainless steels have been subjected to several tests, regarding the influence of vibrations on their mechanical properties and their welding behavior. The samples were made of welded stainless steels. They were subjected to a thermal hardening treatment at a temperature of 950 degrees, with a holding time of 4 hours in the presence of mechanical vibrations. Then comparative tests were performed on both stainless steels at: hardness, tensile test, resilience, microstructural analysis and determination of the longitudinal modulus of elasticity. The research has shown a reduction of the thermo-mechanically influenced area, which contributes to the achievement of a high quality welded joints.

Installation for Producing Mechanical Vibrations used in the Finishing of the Welded Joints Structure

Data publikacji: 31 Dec 2020
Zakres stron: 79 - 84

Abstrakt

Abstract

The paper presents a constructive version of a mechanical vibration generator designed to be used at stress relieving of welded joints. This installation can be used on all brands of steels and welded joints, whether they have magnetic properties or not. In the generator construction a DC motor was used, in order to be able to adjust the speed more easily. The speed adjustment is made with a potentiometer, and the speed measurement is made with a tachometer. The tachometer measures the speeds based on the pulses given by a four-pointed cam rotating between the plates of a capacitor. The vibration system also contains a piezoelectric accelerograph, which is attached to the welded part subjected to vibration, in order to measure the level of vibration and the parameters of the vibration wave.

Retained Water in the Commune of Gogounou in Benin: Inventory, Characterization and Management Mode

Data publikacji: 31 Dec 2020
Zakres stron: 115 - 126

Abstrakt

Abstract

The present work was carried out with the aim of knowing the characteristics and the management made of the agropastoral dams of the commune of Gogounou which are of a great utility for the local populations. To do this, twenty (20) dams were chosen according to the strategic interest that they present for the population, that is to say a polling rate of 87% on all the dams of the municipality. An inventory of the dams was made according to quantitative and qualitative indicators. The results showed the existence of (04) groups of dams according to the technical characteristics and some qualitative variables. The parameters that lead to the degradation of these dams are often related to the age and type of dam and the place of installation. Groups (2 and 4) are agropastoral dams (100%) and more than half of the dams are on flood sites. Results have also shown that there are management committees around all the dams in the commune of Gogounou, but which are mostly non-functional at almost 75%. Also, it has been found that the breeders are mostly transhumant and sedentary who use (100%) dams for watering animals. This cohabitation between farmers and pastoralists does not occur without major conflicts, in particular, that of land whose settlement is generally peaceful. In short, the management of the dams in the commune of Gogounou is a real challenge to be met for a better development, both economically and socially to guarantee the prosperity of the actors and prepare them to adapt to the vagaries of the climate future.

Abstract

Within this paper, a methodology for assessing the flood risk was developed by extracting the essential factors that favor the generation of flood risk. These factors, that had a sufficient number of data for a proper comparative analysis, are: potentially affected population based on population density, total agricultural area, total built-up area and the historical maximum amount of precipitation recorded in 24 hours. The flood risk assessment is presented in the form of indices calculation for all these factors and maps generated which representing the results of the calculation of the above-mentioned factors and the results of the flood risk index calculation.

Urban floods have particularities that must be presented in detail to understand the flood phenomenon, which is why this paper takes into consideration these areas. In order to determine the probability of urban floods, all disturbing factors that may affect the urban area must be taken into account.

The method presented in this paper can be used in sectoral planning activities and integrated planning studies, and for damage assessment.
