TL;DR: In this paper, the effect of fiber orientation on tensile strength of UHPFRC was quantified using the uniaxial tensile test for determining the tensile stress-elongation curves of 22 specimens and the quantitative evaluation of the fibre density and orientation characteristics was performed resorting to an image analysis technique.

TL;DR: In this paper, a BC under a 9.5 m high embankment was instrumented and observed during the construction period, and numerical analyses were performed using a finite-element code capable of considering the construction sequence, the nonlinear behavior of the reinforced concrete structure, and an elastic-plastic behavior for the soil and the interfaces.

TL;DR: A strategy for early damage detection based on multivariate cointegration analysis and statistical process control is proposed and the damage intensities that can be detected using the proposed methodology and the available sensory system are quantified.

TL;DR: In this article, a non-destructive testing (NDT) method based on the ferromagnetic properties of the steel fibres was proposed for estimating the parameters of the underlying physical model, namely, the fibre content and the fibre orientation factor.

TL;DR: In this article, the concept of levels of approximation (LoA) is applied to the determination of the punching shear resistance of reinforced concrete slabs and a procedure is validated for the highest LoA involving nonlinear finite element analysis (NLFEA) with multi-layered shell elements and the critical shear crack theory (CSCT).
