20.500.12556/RUL-17572 Program za dimenzioniranje AB prereza na osno-upogibno in strižno obremenitev diplomska naloga Concrete section analysis software for calculating axial-bending and shear strength graduation thesis V diplomski nalogi predstavimo lasten računalniški program za dimenzioniranje dvojno armiranega betonskega prereza na osno-upogibno in strižno obremenitev v mejnih stanjih nosilnosti. Program je izdelan v programskem jeziku Visual C#®. Pri določanju mejne osno-upogibne odpornosti AB prereza upoštevamo predpostavko o ravnih prečnih prerezih, upoštevamo kompatibilnost deformacij armature in okoliškega betona na medsebojnem stiku, natezno nosilnost betona v računu pa zanemarimo. Sovisnost med napetostmi in deformacijami v betonu upoštevamo skladno z delovnim diagramom tlačenega betona, podanega s parabolo in premico, sovisnost med napetostjo in deformacijo armature pa z idealiziranim bilinearnim antisimetričnim diagramom za jeklo za armiranje. Pri analizi osne in upogibne odpornosti betonskega dela prereza le-tega razdelimo na podprereze in lamele. Program omogoča izračun minimalne oziroma simetrične količine vzdolžne armature. Pri določanju strižne odpornosti AB prečnega prereza upoštevamo strižno nosilnost nerazpokanega dela betonskega prereza, trenje med zrni agregata vzdolž strižne razpoke in moznični učinek vzdolžne natezne armature v strižni razpoki. V kolikor omenjeni prispevki ne zadoščajo za prevzem strižne obremenitve, dokaz strižne odpornosti prereza izvedemo na podlagi modela ravninskega paličja, ki ga sestavljajo natezni pas, tlačna razpora v betonu in strižna armatura. Primernost in uporabnost razvitega računalniškega programa prikažemo na treh različnih računskih primerih. The thesis presents a computer program for the design of a double-reinforced concrete section to axial- bending and shear strength in ultimate limit states. The program is developed in Visual C#® programming language by the author of this thesis. When defining the maximum axial-bending resistance of RC section the following factors are taken into consideration: the assumption of straight cross-sections and the compatibility of contact deformation of the reinforcement with the surrounding concrete. However, the tensile load of concrete in the account is ignored. Interdependency between stress and strain in concrete is considered according to the stress-strain diagram of concrete cylinder test, given by a parabola and a straight line. The interdependency between the stress and the reinforcement deformation is considered according to an idealized antisymmetric bilinear diagram for reinforcement steel. In the analysis of axial and bending resistance of the concrete cross-section the latter is divided into subsections and panels. The program allows the calculation of the minimum quantity and symmetrical quantity of longitudinal reinforcement. In determining the shear resistance of RC cross-section the following factors are considered: the shear bearing capacity of the non-cracked concrete section, the friction between the grains of the aggregate along the shear cracks, and the dowel effect of longitudinal tensile reinforcement in the shear crack. If the contributions mentioned are not sufficient to bear shear load, shear resistance sectional proof is performed based on the model of planar truss consisting of tensile zone, compressive tie in concrete, and shear reinforcement. Adequacy and applicability of the developed computer program is illustrated in three different computational cases. gradbeništvo diplomska dela VSŠ računalniški program armirani beton evrokod Visual C# .NET graduation thesis civil engineering Software reinforced concrete Eurocode Visual C# .NET true false false [M.
