Research ArticleOpen accessIn the abstractA Study of the Effect of Infilled Brick Walls on Behavior of Eccentrically Braced Frames Using Explicit Finite Elements MethodAmir Saedi Daryan, Masood Ziaei, Ali Golafshar et al.Problem statement: Eccentrically Braced Frames (EBFs) are usually infilled by masonry walls, but in common design, the stiffness and lateral resistance of these walls is ignored. Considering the results of carried out tests and studies, it seems that infilled masonry walls have a significant influence on the stiffness and the strength of EBFs. Since experimental test of total frame with … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,196 accessesView PDFCite

Research ArticleOpen accessIn the abstractInfluence of Heat Treatment in Sintering Process on Characteristics of Al2o3-Zro2 Ceramics SystemsA. Rittidech, T. TunkasiriAl2O3-ZrO2 ceramics containing 5-50 mol% ZrO2 were prepared by solid state reaction method. The bulk density, average grain size and microhardness of Al2O3-ZrO2 ceramics system as function of ZrO2 content were investigated. The dense Al2O3-ZrO2 ceramics were successfully by means of carefully control processing parameters that include sintering temperature and heating/cooling rates. These ceramics with higher ZrO2 content was obtained … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,012 accessesView PDFCite
