  1. Ambient and fire behavior of eccentrically loaded elliptical slender concrete-filled tubular columns

    Espinós Capilla, Ana; Romero, Manuel L.; Portolés Flag, Jose Manuel; Hospitaler Pérez, Antonio
    This paper presents the results of an experimental program carried out on slender elliptical hollow section columns filled with concrete. Given the reduced number of experimental results found in the literature on concrete filled tubular columns with elliptical cross-section, the main objective of this paper is to compare the behavior of such innovative cross-sections under ambient and high temperatures. The test parameters covered in this experimental program were the load eccentricity (0, 20 and 50 mm) and the type of infill (plain concrete or bar-reinforced concrete). Six room temperature tests were performed, while other six tests were carried out at...

  8. Optimization of ODHE membrane reactor based on mixed ionic electronicconductor using soft computing techniques

    Lobera González, Maria Pilar; Valero Cubas, Soledad; Serra Alfaro, José Manuel; Escolástico Rozalén, Sonia; Argente Villaplana, Estefanía; Botti Navarro, Vicente Juan
    This work presents the optimization of the operating conditions of a membrane reactor for the oxidative dehydrogenation of ethane. The catalytic membrane reactor is based on a mixed ionic-electronic conducting material, i.e. Ba(0.5)Sr(0.5)Co(0.8)Fe(0.2)O(delta-3), which presents high oxygen flux above 750 degrees C under sufficient chemical potential gradient. Specifically, diluted ethane is fed into the reactor chamber and air (or diluted air) is flushed to the other side of the membrane. A framework based on Soft Computing techniques has been used to maximize the ethylene yield by simultaneously varying five operation variables: nominal reactor temperature (Temp); gas flow in the reaction...
