Published: February 2020

Throughout the past decades, failure of structures threatening the lives of humans had been popular whether through structure failure due to human error such as Hyatt Regency walkway collapse, 1981, terrorist attacks on the American embassy attack in Nairobi, Kenya 1998 and the famous 9/11 attacks in 2001 and many more. As a result of these incidents, The Unified Facilities Criteria (UFC) was developed concerning the progressive collapse issues by analyzing different types of structures under column loss and studying the overall structural behavior. However, the (UFC) didn’t scope on the local behavior of the structural components and its connection under column loss. In this research, the main objective is to study the local behavior of the special moment frame connection (SMC) under column loss. A detailed study is conducted on a 3D model fully designed by adopting the strong-column weak-beam approach following the ACI318-14 regulations. Two frames are selected from the designed structure, interior and exterior frames, to apply the column loss scenario in different locations and different floor levels. The Applied Element Method is adopted in the study. Non-linear time-dependent dynamic analysis is implemented to apply the different column removal scenarios. Twelve case studies are modeled in detail using the Extreme Loading for Structures (ELS) software at which all elements are modeled and analyzed in a 3D model technique. After analyzing the different case studies, structure behavior is observed. Some cases encountered total collapse, other cases encountered partial /local collapse and finally, some survived the column loss scenario. Many parameters are involved and studied in the research. Failure pattern is observed for collapsed cases, the cause of failure is monitored and studied. Special moment connection behavior is studied concerning the shear connection capacity. The location of the column removal with the type of frame selected played an important role in changing the structural behavior from one case to another. As a result, it is not applicable to assume that due to the special moment connection ductility, the structure will be able to resist the column loss in all cases.

The investigation of the depth immersion of the specimens on corrosion rate of steel St3 in 3 % NaCl solution. Simulation of atmospheric corrosion (humid and wet) was performed by immersing of a steel sample by the size of (50×10×2) mm in a neutral solution of 3% NaCl at different depths. By leading the lower boundary of the working surface of the sample to the level of the solution (about 0 mm), humid corrosion was simulated, submerged to a depth of 2 mm (up to the upper boundary), wet corrosion, and 10 mm from the upper boundary - the electrolyte volume. The developed method allowed to carry out electrochemical researches by the method of polarization curves. The polarization curves were measured in the potentiodynamic mode with the potential scanning rate of 5∙10-4 V/s .The working electrode was a sample of steel St3 by the size (10×50×2) mm. A work surface (10×2) mm was separated on the sample, the rest of the surface was isolated with a non-conductive varnish. The results of the investigation of the effect of depth immersion of samples into electrolyte solution on corrosion rate of St3 steel are presented. The conditions of “humid” and “wet” atmospheric corrosion of the metal were simulated by the immersion of samples on a depth from 0 to 10 mm into 3% sodium chloride solution. It was found, that on the base on determination of the rate of particular electrode reactions occurring on the electrode at various depths of its immersion into the solution, the corrosion rate of steel St3 was determined by the value of the limiting diffusion current.It was shown that the value of limiting current increases from 0.51 to 2 A/m2 with decreasing of the film thickness. It has been established that the cathodic process rate depends both on the concentration of oxygen in the layers of the solution, which are at different distances from the solution/air boundary, and on the speed of its diffusion to the metal surface. Because the method of polarization resistance allows to measure the currents smaller than the currents of oxygen reduction in thin films of the solution, it can be used to estimate the rate of atmospheric corrosion of steel. Based on simulation of humid and wet atmospheric corrosion the effect of immersion depth of the specimens on the cathodic reaction rate of steel St3 in 3 % NaCl solution was established. The cathodic current density (limit diffusion current) is raised from 0,51 to 2 A/m2 under decreasing of immersion depth. The suggested method of simulation of atmospheric corrosion may be used for electrochemical investigations in thin films of moisture of different thickness which are form on the metals and sensors surfaces. The possibility of application of polarization resistance method for atmospheric conditions was presented.

Investigation of the effect of the concentration of aluminum oxide nanoparticles on the micro- and macro-rheological properties of the melt of a polypropylene / copolyamide (PP / CPA) mixture to control the morphology of nanofilled composites. The starting polymers and nano-additive were melt blended on a worm-disk extruder. The degree of dispersion of the component of the dispersed phase in the matrix was evaluated by micrographs of cross sections of the extrudates of the mixtures. The types of PP structures and their dimensional characteristics were studied using an optical microscope. The effective viscosity of the melts was determined on an MB-2 micro viscometer, and elasticity was calculated as the ratio of the extrudate and die diameters. It is shown that the introduction of a PP / CPA mixture (0.1÷3.0) mass. % Al2O3 nanoparticles makes it possible to control the process of structure formation of the component of the dispersed phase. In this case, the average diameter of PP microfibrils decreases and their mass fraction increases. The maximum effect was achieved when the content of nanoparticles 1.0 mass.%. It has been established that the macro-rheological properties of melts of nanofilled systems are determined by their morphology. The formation of anisotropic structures (PP microfibrils) with smaller diameters causes a decrease in viscosity and an increase in the elasticity of the melts of mixtures, in contrast to similar indicators for PP and CPA. It was shown that Al2O3 nanoparticles do not affect the type of morphology of the thermodynamically incompatible PP / CPA mixture - in nanofilled compositions, as in the initial one, a microfibrillar structure is formed. The modifying effect of nanoadditives is manifested in the formation of a larger number of PP microfibrils and a decrease in their dimensional characteristics. The studied nanoparticle does not interfere with the stable processing of the PP / SPA mixture into fibers and films on extrusion equipment and does not complicate the process of extraction of the matrix polymer from composite extrudates. The introduction of Al2O3 nanoparticles will make it possible to obtain composite products and fine-fiber materials with improved characteristics due to the regulation of phase morphology.

For research, a MICROmed device was used, which has a temperature control and a mixing function. Weight corrosion tests were evaluated gravimetrically using the brand scales CERTUS Balance CBA-150-0.02. pH of solutions was measured using pH - meters mark 150 MA. Processing of the results was carried out by mathematical planning of experiments using the software package Exel 2016. It proposed a low-temperature chemical synthesis method by reacting hydrogen alloys of aluminum with alkali solutions with additives activators. The basic patterns of change in the dissolution rate of the AK7 alloy and formation of hydrogen halide from the impact of ions in alkaline solutions and its influence on the process condition of the alloy surface and reaction products. In this alloy, the most influential is the admixture of silicon, which is 3–6% by weight. The influence of the kinetic parameters of dissolution of the AK7 aluminum alloy on the synthesis of hydrogen as a source of environmentally safe thermal energy is determined. The dependences of the process of hydrogen evolution in alkaline solutions by the mechanism of hydrogen depolarization on the nature of the aluminum alloy and impurities of activators in the electrolyte are established. The processes of the metal chemical cycle of hydrogen production have been studied; they create the conditions for the further development of the technological process of aluminodepolarization synthesis of hydrogen without the use of membrane electrolyzers. This method is important for the needs of small energy in small quantities.
