Abstract Along with the advance of working face, coal experiences different loading stages. Laboratory tests and numerical simulations fracture damage evolution aim to better understand structural stability layers. Three-dimensional lab are performed samples reconstructed using X-ray computer tomography (CT) technique get detailed information about deformation state. discrete element method (DE...
Uniaxial compressive stress-strain curves of several groups basalt fiber crumb rubber mortars (BF-CRM) with different contents are tested. By comparing the GZH model, improved values parameters BF-CRM constitutive model based on obtained. Then, taking supporting scheme main substation mine as background, using FLAC3D to simulate roadway support, replace ordinary in original and combining triaxi...
Triaxial consolidated drained, unconfined compression, and CBR tests have been conducted in order to study the stress-strain, strength, and volume change characteristics of fine sand specimens reinforced by polymeric fibers made from carpet wastes. The variables are aspect ratio (length/width) and weight percentage of the fibers. The results indicate that the peak strength and total volume chan...
in this research, using the modified compression field theory (mcft), a new truss based model is proposed to predict the behavior of reinforced concrete coupling beams with diagonal reinforcement. the model is able to consider the effects of shear and axial forces and bending moment, simultaneously. the proposed model includes a nonlinear shear spring, an axial spring, two inclined truss member...
