This paper is a continuation of the research on reinforcement of masonry walls using a combination of metal frames and mechanical dampers. This paper analyzes a single metal frame with and without reinforcement with mechanical dampers in order to have a clearer insight into the behavior of individual reinforcement components. It presents an overview of the basic characteristics of mechanical dampers, their configuration and combinations with metal frame, and special emphasis is placed on their earthquake behavior. The results of the numerical analysis for a single metal frame were obtained using two modern software packages, ABAQUS and SAP2000. After the results of the individual metal frame were obtained, the metal frame was strengthened by applying mechanical dampers and analyzed. [ABSTRACT FROM AUTHOR]

Many masonry structures are located in seismically active areas where the action of seismic forces has revealed their vulnerability. Since such structures are built of composite materials, attention should be paid to all the structural elements that make it up. The objective of this paper is to present the procedure and analysis results for a masonry building in order to determine its seismic resistance. The AmQuake software, which facilitates the design and calculation of masonry buildings according to European standards and norms, was used for the analysis. By using the pushover method, the system response to an increasing horizontal force with a constant vertical load is monitored through the calculation. Based on the calculation results, a conclusion on the conducted analysis is given. [ABSTRACT FROM AUTHOR]

In this paper a new shape optimization algorithm is presented. As a model application we consider state problems related to fluid mechanics, namely the Navier-Stokes equations for viscous incompressible fluids. The general approach to the problem is described. Next, transformations to classical optimal control problems are presented. Then, the dynamic programming approach is used and sufficient conditions for the shape optimization problem are given. A new numerical method to find the approximate value function is developed. [ABSTRACT FROM AUTHOR]

A class of fourth-order neutral type difference equations with quasidifferences and deviating arguments is considered. Our approach is based on studying the considered equation as a system of a four-dimensional difference system. The sufficient conditions under which the considered equation has no quickly oscillatory solutions are given. Finally, the sufficient conditions under which the equation is almost oscillatory are presented. [ABSTRACT FROM AUTHOR]
