“…The bending capacity of TRC could be improved by pre-stressing textiles. Test results showed that the first-crack load capacity of the specimens with pre-stressing textile was increased by 85%, compared with the non-prestressed specimens [119]. The flexural properties of 3D and 2D AR-glass textiles reinforced cementitious matrix are also compared.…”

Textile reinforced concrete (TRC) is an innovative structure type of reinforced concrete in which the conventional steel reinforcement is replaced with fibre textile materials. The thin, cost-effective and lightweight nature enable TRC to be used to create different types of structural components for architectural and civil engineering applications. This paper presents a review of recent developments of TRC. In this review, firstly, the concept and the composition of TRC are discussed. Next, interfacial bond behaviour between fibre textile (dry and/saturated with polymer) and concrete was analysed considering the effects of polymer saturation, geometry and additives in polymer of the textile. Then, the mechanical properties (including static and dynamic properties) of TRC were reviewed. For static properties, the mechanical properties including compression, tension, flexural, shear and bond properties are discussed. For dynamic properties, the impact, seismic and cyclic properties were investigated. Furthermore, the durability of TRC under different environmental conditions, i.e., temperature/fire, humidity and wet–dry cycles, freeze–thaw, chemical and fatigue were discussed. Finally, typical engineering applications of TRC were presented. The research gaps which need to be addressed in the future for TRC research were identified as well. This review aims to present the recent advancement of TRC and inspire future research of this advanced material.

The demand for building quality in the construction of structures is a major requirement. One part of the structure is the floor slab work. The main obstacle is when the floor slab is loaded there will be deflection and bending moment. Meanwhile, there are demands for shorter work times at lower costs. This study aims to analyze the concrete slab against the flexural strength test, compressive strength test and tensile strength test of plate reinforcement. In this study, plate reinforcement used plain steel with a diameter of 6 mm and 8 mm. Then the plain iron reinforcement plate was compared with the M6 and M8 wiremesh reinforcement plates. The results showed that the flexural strength test for plain iron reinforcing plates with a diameter of 6 mm was 45000 Kg.cm, while for a concrete slab with wiremesh M6 reinforcement it was 42500 Kg.cm then for reinforcement with a diameter of 8 mm it was 32500 Kg.cm while wiremesh M8 was 57500 Kg. .cm. This shows that the concrete slab with wiremesh reinforcement is better able to accept the load, as well as better moment capacity in bending, compressive and tensile tests compared to conventional slabs.

There are many novel applications of space-time decoupled least squares and Galerkin formulations that simulate wave propagation through different types of media. Numerical simulation of stress wave propagation through viscoelastic medium is commonly carried out using the space-time decoupled Galerkin weak form in site response problem, etc. In a recent investigation into accuracy of this formulation in simulating elastic wave propagation, it was shown that the diffusive and dispersive errors are greatly reduced when space-time coupled least squares formulation is used instead in variational form. This paper investigates convergence characteristics of both formulations. To this end, two test cases, which are site response and impact models for viscoelastic medium, are employed, one dominated by dispersive and the other by diffusive numerical error. Convergence studies reveal that, compared to the commonly used space-time decoupled Galerkin and the coupled least squares formulation has much lower numerical errors, higher rates of convergence, and ability to take far larger time increments in the evolution process. In solving such models, coefficient matrices would require updating after each time step, a process that can be very costly. However large time steps allowed by cLs are expected to be a significant feature in reducing the overall computational cost.
