This paper presents a computational rational model to predict the ultimate and optimized load capacity of reinforced concrete (RC) beams strengthened by a combination of longitudinal and transverse fiber reinforced polymer (FRP) composite plates/sheets (flexure and shear strengthening system). Several experimental and analytical studies on the confinement effect and failure mechanisms of fiber reinforced polymer (FRP) wrapped columns have been conducted over recent years. Although typical axial members are large-scale square/ rectangular reinforced concrete (RC) columns in practice, the majority of such studies have concentrated on the behavior of small-scale circular concrete specimens. A high performance concrete, known as polymer concrete, made up of natural aggregates and an orthophthalic polyester binder, reinforced with non-metallic bars (glass reinforced polymer) has been studied. The material is described at micro and macro level, presenting the key physical and mechanical properties using different experimental techniques. Furthermore, a full description of non-metallic bars is presented to evaluate its structural expectancies, embedded in the polymer concrete matrix. In this paper, the mechanism of mechanical interaction of smooth and lugged FRP rods with concrete is presented. A general modeling and application of various elements are demonstrated. The contact parameters are defined and the procedures of calculation and evaluation of contact parameters are introduced. The method of calibration of the calculated parameters is presented. Finally, the numerical results are obtained for different bond parameters which show a good agreement with experimental results reported in literature
Nahdliyins, die in Deutschland wohnen, haben im Allgemeinen mindestens zwei große Vorteile. Der erste Vorteil ist die frühe Exposition der Theorie und Praxis des Islam ahlussunnah wal Jamaah an-nahdlyah, der später als Islam Nusantara bekannt wurde. Der zweite ist der Kontakt mit der akademischen und beruflichen Welt in Deutschland in einem Zeitraum von mehr als zehn Jahren, insbesondere in den Bereichen Naturwissenschaft und Technologie.Im Idealfall ist Islam Nusantara nicht nur als Orientierung positioniert, sondern als Kapital, um sich auf drei Arten zu bewegen. Zunächst auf dem Gebiet der Aqidah: Das Konzept der Aqidah Seket (50) spielt eine wichtige Rolle als grundlegendste Grundlage nicht nur für um Gott zu kennen, sondern auch um Splitter und gegensätzliche Ideen (vom Radikalismus über Takfiri bis hin zum Atheismus, der leider kürzlich von mehreren Wissenschaftlern populär gemacht wurde) abzuwehren.
