Survey Of Influence Of Opening Area To Wall Area Ratio On Stiffness And Yielding Resistance Of Concrete Shear Wall SystemPages 58-70The presence of openings in the concrete shear wall system reduce the power of the system in loading, so in this study first using a valid experimental specimen validity of results from an ANSYS software has been done.
after ensuring the modeling and obtained results concrete frame with concrete shear wall system return function have been investigated using modeling the structures with different percentage of opening to whole of wall in ANSYS software and doing the non-linear static analysis (hysteresis) according to ATC 24 results from hysteresis analysis of models show the system power reduction and theyre complicity of the system collapse in energy dissipation in cycling loading.Keywords: Shear Wall, Finite Element Method, Energy Absorption, Hardness
Pages 71-78This article proposes to present the possibility of transporting water in the form of superheated steam by applying the thermodynamic process of vapors. The transport of the superheated vapors has an advantage because of the low density and its reduced coefficient of exchange. The thermal power of the steam plant is determined using the temperature-entropy (T-S) and enthalpy-entropy (H-S) diagrams. This power is then compared with the power of a hydraulic pump placed under the same conditions, in order to proceed with the possible improvement of the characteristics of the thermal installation.Keywords: Transport Of Vapors, Superheated Steam, Vaporization Process, Steaming, Steam Use
