The scope of this study is to look at the effect supplying a non-prismatic cross-section on flexural strength one-way continuous slabs reinforced concrete (RC) with two spans under repeated load. research aims ability increase stiffness which leads saving construction costs. For purpose, experimental investigations were carried out; work consisted fabrication and testing six two-span RC same vo...

We present here the experimental results from research conducted on negative refraction and focusing by a two-dimensional (2D) left-handed metamaterial (LHM) slab. By measuring the refracted electromagnetic (EM) waves from a LHM slab, we find an effective refractive index of -1.86. A 2D scanning transmission measurement technique is used to measure the intensity distribution of the EM waves tha...

[1] The effect of rheology on the evolution of the slab-tip during subduction initiation is analyzed using 2-D numerical flow models. Experimentally determined flow laws have both strong temperatureand stress-dependence, which leads to large local variations in viscosity with direct consequences for subduction initiation. We find that models with Newtonian viscosity lead to flat or coupled subd...

Blast simulators are capable of applying blast-like loading to components in a safe and controlled laboratory environment, overcoming the inherent shortcomings blast testing terms data acquisition, test cycle time, cost. In this paper, reasonable assumptions refinements made shape impact module, key component simulator, achieve diversity simulated loading. By designing four rubber shapes, impor...

In this study, the expansion and deformation of alkali–silica reaction (ASR)-affected concrete structures under natural environment multiaxial stress state are predicted. The performance ASR model proposed in previous research is quantitatively investigated terms relative humidity, stress, temperature dependencies based on experimental results. simulation results indicate that humidity-dependen...
