Smooth cutting pattern generation technique for membrane structures using geodesic line on subplane and spline interpolationSHON Su-deok1, LEE Seung-jae1, LEE Kang-guk2(1. School of Architectural... for smooth geodesic patterning of membrane structures were investigated. For the geodesic search, adjustment of the subplane of the extracted elements series was proposed, and various spline......
cover, load ratio, ratio of reinforcement and the tensile strength of concrete are great; the tensile membrane action of two-way RC slab under elevated temperature is beneficial to its fire resistance... of RC slab. Key words: elevated temperature; numerical simulation; two-way slab; tensile membrane action 火灾中,钢筋混凝土楼板直接承受火荷载,而且板的厚度较小,钢筋保护层较薄,所以火灾时钢筋混凝土楼板是整个结构中最薄弱的环节.钢筋混凝土楼板火灾受损的主要原因是板中的钢筋因高温作用而强度降低......
and control of proton exchange membrane fuel cell CHEN Yue-hua(陈跃华), CAO Guang-yi(曹广益), ZHU Xin-jian(朱新坚) (Department of Automation, Shanghai Jiaotong University, Shanghai 200030, China) Abstract: A neural network model and fuzzy neural network controller was designed to control the inner impedance of a proton exchange membrane fuel cell (PEMFC) stack. A radial basis function (RBF) neural network......
