Special Issue Information

Dear Colleagues,

Frames are structural systems largely adopted in civil engineering works. Their ability to resist gravitational and lateral loads depends on the bending mechanisms that develop in beams and columns. Reinforced concrete (RC) members are bending-resistant structural elements whose capacity is a direct consequence of the complementary presence of compressive (concrete) and tensile (steel reinforcement) resisting materials. Due to the reduced maintenance cost and ease of construction, RC frames are among the most common structural resisting systems in buildings. Resistance when exposed to fire and robustness under thread-independent damage scenarios are some of the capabilities of RC frames. The reliability of such structures is a key topic for the structural design and safety assessment of new and existing buildings in all possible scenarios, ordinary and exceptional.

The aim of this Special Issue is to attract leading researchers in the area of the reliability assessment of RC frame buildings, in an effort to highlight the effects of aging, ordinary and exceptional loads, thread-independent damage scenarios or other phenomena that can occur during the working life of the constructions such as, but not limited to, maintenance and repair works. The accepted contributions will focus on structural reliability and will include theoretical considerations, numerical and experimental modeling, and applications to specific and well-detailed case studies.

With the development of the economy and the rapid increase in traffic volume, an overload phenomenon often occurs. This paper studied a vehicle load identification technique based on orthotropic bridge deck stress monitoring data. The strain responses on the lower edge of multiple U-ribs were collected under vehicles crossed the deck. Firstly, an index based on the cross-correlation function of strain response between different measurement points on the same U-rib was used to evaluate vehicle speed. Secondly, a cosine similarity index was proposed to locate the transverse position of the vehicle. Finally, the unknown vehicle load was identified on the basis of a calibrated strain response area matrix. The effectiveness and anti-noise performance of the proposed method were verified using numerical simulation. An experimental model was designed and some strain gauges were installed to measure the strain response, and the test was carried out to further verify the algorithm’s performance. Numerical and experimental results show that the proposed method could effectively identify the vehicle load with good anti-noise performance. Moreover, a calibration space was provided to guide practical engineering applications. The proposed method does not damage bridge decks, does not affect traffic, and is economical. Full article

Construction works, especially in the case of large road or tunnel investments, require the active participation of surveyors. It applies to classic geodetic procedures such as staking out or conducting control measurements and continuously monitoring displacements and deformations. Negative factors at surveying sites may hinder the implementation or directly affect the instruments, especially total stations. Heavy dust and rainfall containing harmful and destructive substances can be mentioned here. Contemporary measuring instruments are technologically complex and expensive devices, often exposed to the sun, wind, and frost. To mainly protect robotic total stations, various preventing housings are used. Practice shows, however, that these are half-hearted solutions, often negatively influencing the accuracy of the surveys. Based on the authors’ professional and scientific experience, a technological line using the modeling and 3D printing of protective housings for robotic electronic total stations has been developed. The workflow includes dedicated online modeling and printing unique instrument covers that best suit certain sites. The prototype was shielded with an additional hydrophobic layer and tested in a geodetic laboratory. The validation results confirm the high usability of the technological line while maintaining the appropriate millimeter level positioning accuracy and effectiveness of the geodetic monitoring.
