Size effectsCompressive strengthDynamic increase factorThree high-performance concrete (HPC) materials with different specimen geometries were characterized using Kolsky compression bar techniques to study the strain rate and specimen size effects on their uniaxial compressive strength. A large-diameter Kolsky...
Strain-rate effects on concrete behavior In this paper, a previously developed meso-scale model for concrete, called the Confinement Shear Lattice (CSL) model, is extended in order to include the ... G Cusatis - 《International Journal of Impact Engineering》 被引量: 109发表: 2011年 A Testi...
A literature review was conducted to determine the extant data characterizing the effects of strain rate on the tensile strength of concrete. In particular, additional new data by Ross et al. were considered. This data supports the dynamic increase factor (DIF) being a bilinear function of the ...
Effects Of Strain Rate On Concrete Strength Subjected To Impact Load -Dynamic Compressive Strength Test By Split Hopkinson Pressure Bar MethodThe home of the Transactions of the Wessex Institute collection, providing on-line access to papers presented at the Institute's prestigious international ...
An effect of strain rate to the seismic behavior of reinforced concrete frame structures was examined by a shaking table test of an actual size three-story building frame. The yield hinges were formulated at the beam ends and the bottom of columns of the first story. The strain rate of main...
on 1 Dec 2010, Accepted on 16 Jan 2011 ABSTRACT Strain-rate effect on the compressive strength of brittle materials is normally characterized using split Hopkinson pressure bar (SHPB) technique. It has been found recently that the transition strain-rate observed in SHPB tests on concrete-like ...
