As an economic and safe structure, Bi-steel is widely used in reinforced concrete with less consumption of steel. In this paper, III Bi-steel concrete beam has been analyzed. Through careful observation and theoretical analysis, the new calculating formulae for structural rigidity and crack have been formulated for this Bi-steel concrete beam. And structural rigidity and the crack features have...
Title of Document: NUMERICAL STUDY OF SEISMIC BEHAVIOR OF HIGH STRENGTH STEEL REPLACEABLE SHEAR LINKS Huiling Hu Master of Science, 2015 Directed By: Yunfeng Zhang, Professor Department of Civil and Environmental Engineering Eccentrically Braced Frames (EBFs) have been widely used in seismic protection and remediation in the recent years. However, the seismic behavior of shear links made of hig...
Context. Water maser emission is a powerful tracer of the presence of embedded sources in dense clouds since it requires elevated temperatures (>100 K) and densities (>107 cm−3) that can be found in circumstellar disks and/or jets/outflows associated with Young Stellar Objects. Bright rimmed clouds compressed by ionization fronts from nearby massive stars are considered good examples of externa...
We have characterized the binary LB films of merocyanine dye (MS) and arachidic acid (C20) before and after hydrothermal treatment (HTT), which is defined as a heat treatment under relative humidity of 100%, focusing on the morphology studied by bright field (BF) microscopy and fluorescence (FL) microscopy. BF microscopy observation has revealed that the as-deposited MS-C20 binary LB film is fo...
BACKGROUND GNE myopathy is a rare genetic disease characterized by progressive muscle atrophy and weakness. It is caused by biallelic mutations in the GNE gene that encodes for the bifunctional enzyme, uridine diphosphate (UDP)-N-acetylglucosamine (GlcNAc) 2-epimerase/N-acetylmannosamine (ManNAc) kinase. Typical characteristics of GNE myopathy include progressive myopathy, first involving anter...
Introduction In the 1970s, exterior bonded steel reinforcement was used sporadically to reinforce bridges to attain higher service load capacities. This steel post-strengthening system consisted of steel straps bonded with epoxies to the exterior of concrete beams. An alternative to the steel retrofit is woven carbon fiber reinforced polymer fabric applied in the same manner as steel. Carbon fi...
