“…Various types of reinforcements have been employed for 3D printing, such as steel micro cable, U-nail, mesh, vertical insertion of bars, and short fibers, among others. Studies have reported positive results after the insertion of reinforcement, demonstrating significant improvements in compressive strength (Kazadi et al 2022;Mechtcherine et al 2019;Alonso-Canon et al 2022;Nodehi et al 2022;Lim et al 2020). Examples of such studies and the observed strength changes after the insertion of reinforcement are discussed below.…”

All industries have embraced three dimensions printing, which is shown to offer several advantages. This article examines the use of 3D printing in the construction industry. Concrete is the primary component when using 3D printing in a building; reinforcements are either seldom employed or not used at all. Although having many advantages, this building approach has some drawbacks. The substance utilized to make the printable paste combination is currently being researched because this is a novel technology. To meet the needs of 3D printing, material use, and mixing proportions have considerably different qualities from those of conventional building methods. As a fundamental need, three-dimensional printed concrete(3DPC) demands that an object be printed, buildable, resilient, and consistent. Knowing that 3D printing seldom uses reinforcement to increase strength, durability, or stability is crucial. This article offers a concise overview of all the applications, difficulties, and prospects for 3DPC. The article starts out with defining 3D printing before going on to discuss its prerequisites and challenges. It also examines the fundamentals of 3D printing in concrete, including its background, uses, and advantages. In this article, printing techniques and materials are thoroughly examined, and a material that is optimum for sustainability is suggested.

“…As it has been discussed in the numerical simulations sections (2.3 and 3.2), the ARs could stand the forces exerted by the water without the need of reinforcement bars. The use of fibers to reduce the section of the ARs was also discarded, because the maximum increment on flexural strength that fibers could supply would not be more than % [40], which is considered still quite low to be contemplated as a substitute of rebars.

“…In particular, many works related to 3D printing of elements or entire buildings made of concrete and reinforced concrete should be noted here [ 6 , 7 , 8 ]. The authors develop new technologies for printing concrete objects, allowing for the creation of complex shapes of concrete surfaces, which are characterized by the good print quality and geometric accuracy [ 9 , 10 ]. In recent years, some studies have been conducted on the modal properties of structures made in 3D printing technology.…”

On the Possibility of Using 3D Printed Polymer Models for Modal Tests on Shaking Tables: Linking Material Properties Investigations, Field Experiments, Shaking Table Tests, and FEM Modeling

In this article, the possibility and the pertinence of using 3D printed polymeric materials for models in modal tests on shaking tables were recognized. Four stages of the research have been linked: The material properties investigation, the field experiment on the modal properties of the reinforced concrete chimney (a prototype), the shaking table tests on the modal properties of the 3D printed polymer model of the chimney, scaled according to the similarity criteria, and the numerical calculations of the FE model of the 3D printed mockup. First, the investigation of the properties of 3D printed polymer materials revealed that the direction of lamination had no significant effect on the modulus of elasticity of the material. This is a great benefit, especially when printing models of tall structures, such as chimneys, which for technical reasons could only be printed in a spiral manner with the horizontal direction of lamination. The investigation also proved that the yield strength depended on the direction of the lamination of the specimens. Next, the natural frequencies of the chimney, assessed through the field experiment and the shaking table tests were compared and showed good compatibility. This is a substantial argument demonstrating the pertinence of using 3D printed polymer materials to create models for shaking table tests. Finally, the finite element model of the 3D printed polymer mockup was completed. Modal properties obtained numerically and obtained from the shaking table test also indicated good agreement. The presented study may be supportive in answering the question of whether traditional models (made of the same material as prototypes) used in shaking table tests are still the best solution, or whether innovative 3D printed polymer models can be a better choice, in regard to the assessment of the modal properties and the dynamic performance of structures.
