Self-compacting concrete (SCC) is a new generation of high-performance concrete, known for its excellent deformability and high resistance to segregation and bleeding. Nonetheless, SCC may be incapable of resisting shear because the shea... A Nasiri 被引量: 4发表: 2014年 Behavior of reinforcement...
The paper centres on the DIN equation for lateral-torsional buckling of steel beams and its use of the ? coefficients for bending and warping. Using a finite element program the author was able to determine relative warping stiffnesses for ten joint types beam-to-column connections). He then ...

This study describes the behavior of ultra-high-performance-concrete (UHPC) beams with GFRP and steel reinforcements. The experimental results were presented and the influences of parameters, including reinforcement ratio and longitudinal rebar type on the flexural performance of the UHPC beams, were in...
(kx/Ω) are the polar coordinates on thekx–ωplane, andR0is the modulated radius. Equation (1) also describes the strong correlation between spatial frequencykxand temporal frequencyωinside this beam, implying that changing the spectral properties also changes its spatial properties. The field ...

(MCFs) for twisted space-frequency and space-time Gaussian Schell-model (GSM) beams. Using the Fresnel approximation to the free-space Green’s function, we then paraxially propagate the CSD and MCF to any planez>0. We discuss the beams’ behavior as they propagate, with particular emphasis...
Ultra-high performance concrete (UHPC) is a special type of concrete with extraordinary potentials in terms of strength and durability performance. Its production and application implement the most up-to-date knowledge and technology of concrete manufacturing. Sophisticated structural designs in bridges an...
the rest being below threshold and not surviving. The spectral properties of the individual longitudinal modes can be understood by treating the resonator as a Fabry–Perotetalon. Theirspectral width, δν, is given in terms of the resonator'sfree spectral range, FSR =c/2L, and its finesse,...
