Special Issue Information

Dear Colleagues,

Reinforced concrete (RC) structures are widely used almost all over the world for decades. The continuous development of concrete technology (e.g., high strength concretes) and reinforcement methods (e.g., non-metallic reinforcement and fibre reinforcement concrete) creates new possibilities in designing RC elements, but it also opens new problems that need to be solved and new questions to be answered. Thus, knowledge about new possibilities and limitations is required for the proper application of new materials/techniques. At the same time, the growth of numerical methods provides new tools to analyse the above issues. Scientific (but also commercial) software tools allow very sophisticated and detailed simulations; however, again, vast expertise is becoming essential for obtaining physically meaningful results. The efficient (and safe) design process of RC structures requires both a good understanding of the physics of the problem investigated and the proper choice and usage of the applied numerical tool.

Topics of the Special Issue "Design and Simulation of Reinforced Concrete" include but are not limited to the following:

  • Design of RC structures (with aspecial focus of application of new materials and techniques);
  • Simulation of RC structures with: Finite Element Method (smeared or discrete cracks), Discrete Element Method or other numerical approaches;
  • Analysis of the interaction between concrete and reinforcement (experiments and simulations);
  • Application/comparison/critical assessment of national and international standard codes;
  • Durability and long-term behaviour of RC structures (e.g., corrosion or creep phenomena);
  • Environmental aspects in designing RC structures.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Precise evaluation for flexural ultimate capacity of bridges which are subjected to the collision of over-height trucks is essential for making decisions on corresponding maintenance, strengthening or replacement. When the span of a cross-line continuous bridge with a double-box girder was hit by an overly high vehicle, the concrete floor of one girder was severely damaged, and part of the prestressed strands and reinforcements in the girder were broken. After the double-box girder was removed and separated into two single box girders, the ultimate flexural capacity of both box girders was studied by destructive tests, and a comparison was made between the damaged and undamaged girders. Moreover, finite element analysis was conducted to simulate the failure process. The results show that the flexural bearing capacity of the damaged box girder decreased by 33%, but it was still 1.07 times greater than the design bearing capacity, which basically meets the design requirements. Also, the damaged box girder showed a desirable serviceable limit state for three-axle vehicles and five-axle vehicles, but showed an undesirable serviceable limit state for six-axle vehicles. This study shows that repairing or strengthening the damaged span may be better than demolishing and rebuilding the whole superstructure bridge. Full article
