The scope of this work is threefold: (i) to develop a new model within the framework of hydro-mechanical – damage coupling that can account for the coupling between microcrack (damage), water diffusion and shrinkage at stake for concrete secondary creep; (ii) to implement it in an existing hydro-damage lattice model; (iii) to validate the model with respect to the flexural creep of Fiber Reinforced Concrete (FRC) and Mortars under high sustained load level.

In this article, the research team proposes a costeffective IoT-based approach, integrating data like SCADA, to enhance management and monitoring convenience. The research outcome aims to design an electrical cabinet that includes various mechanisms to detect, and safeguard loads from potential incidents, while also being capable of collecting operational data, recording incident occurrences, and integrating with the central management system at the construction site.

In this paper, the continuous stiffness measurement (CSM) indentation is employed to investigate fatigue mechanical properties of structural steel under cyclic loading. For this purpose, several representative analytical approaches were introduced to estimate the basic mechanical properties including Young’s modulus and indentation hardness from the characteristics of the loading/unloading curves.

A big question in the numerical approaches for the mechanical behavior of the textile-reinforced concrete (TRC) composite under tensile loading is how to model the cracking of the cementitious matrix. This paper presents numerical results of 3-D modeling of TRC composite in which the non-linear behavior model was used by considering the cracking for the cementitious matrix.

This paper presents a procedure to design cellular composite beams according to EN 1994-1-1. In addition, a parametric study is carried out to evaluate the influence of circular opening geometry to ultimate load and failure mode of a series of cellular composite beams. As a result, an optimal dimension of cellular beam is proposed.

The small punch test with an application of a relatively small specimen has recently become a reliable material mechanics testing method. In this study, the small punch test is set up based on the conventional mechanical testing machine for SUS304 stainless steel to evaluate the mechanical properties of SUS304 steel at different displacement rates of the punch in quasi-static loading condition in the case of with and without heat treatment.

In this study, a methodology was created to evaluate the values of the yield stress of materials based on the grain boundary strengthening equation. This method was constructed by observing the average grain size and determining the mechanical properties of three microstructural phases in the weld zone (i.e. based metal, heat-affected zone, and weld metal).

This paper investigates the influence of intergranular friction and grain size distributions on the initial void ratio of a granular sample subjected to isotropic compression loading. In the field of geomechanics, besides the loading path and evolution of microscopic properties, the initial void ratio is a crucial and key factor that governs the mechanical behavior of geomaterials.

In this work, nano-SiO2 have been used as nanocarriers for loading Ce(III) ions (SiO2@Ce3+). After loading, silane coupling agent has been used to modify these nanocarriers (m-SiO2@Ce3+). Then, these modified nanocarriers were added as green inhibitors into the inner epoxy coating matrix, which was based on the epoxy resin (DER 671X75) and hardener (polyamide Epicure 3125). Morphological study by FE-SEM showed that the spherical nanoparticles (mSiO2@Ce3+) were in size < 100 nm and dispersed rather homogeneously into the polyme matrix.

A major objective of the research presented here is to develop a link between the two approaches by establishing the relationship between the bridge component condition and the capacity and serviceability limits of the structure. A comprehensive review of literature identified methods of predictive modelling of bridge component condition change using different approaches. The review also indicated that a key to the proposed linkage is considering specific degradation mechanisms in predicting bridge deterioration.

This work presents results from a numerical investigation on the influence of fluid-structure interaction (FSI) on the dynamic response of thin steel plates subjected to blast loading. The loading was generated by a shock tube test facility designed to expose structures to blast-like loading conditions. The steel plates had an exposed area of 0.3 m × 0.3 m and experienced large deformations during the tests.
