Special Issue Information

Dear Colleagues,

With the evolution of human society, there has been an increasing number of functional and convenient engineering structures; therefore, the sustainability challenges of engineering structures are also increasing. On the one hand, engineering structures such as tunnels, dams and buildings may face a series of safety risks during the construction process, posing threats to the personal safety of the construction personnel and the stability of the related engineering structures. On the other hand, these engineering structures may suffer from various loads during normal operation, such as construction disturbance, earthquakes, and explosions, etc., which seriously threaten the safety and stability of engineering structures.

In the 21st century, the rapid urbanization of countries around the world draws the attention of researchers to the risks involved in the construction and operation of infrastructure. Scholars and practitioners around the world conducted many studies on "Engineering Structure Safety and Risk Management of Sustainability", and proposed many new mathematical and experimental methods to optimize the design of engineering structures, based on a certain level of risk adaptation to ensure the reliability of engineering structures and safe operations.

This Special Issue provides a forum for the presentation and discussion of the latest theories and methods in "Engineering Structure Safety and the Risk Management of Sustainability" from a multidisciplinary perspective. This Special Issue also welcomes review articles on current, state-of-the-art sustainable engineering processes. In addition, topical papers related to the topic of "Engineering Structural Safety and Risk Management of Sustainability" that are not included in the list below are also welcome:

Seismic performance of engineering structures;
Reliability assessment of engineering structures;
Dynamic response of engineering structures;
Engineering structure safety control;

Abstract

In this paper, an experiment is carried out to acquire the dynamic mechanical properties of a simulated sandstone tunnel by a dual DIC system. The sandstone tunnel is simulated by large sandstone with a prefabricated hole in the center. The speckle size required by DIC system was evaluated, and the results showed that for large specimens a marker pen could be used to spot speckles and make sure that the diameters of speckle points in an image should be ranged from three to five pixels. The dual DIC system is composed of a low-speed camera and a high-speed camera. The low-speed camera is used to record the speckle patterns of the sandstone in one side during the whole process of compression load, and the high-speed camera is placed in the other side to record speckle patterns for 11.5 seconds before and after failure. It is realized that monitoring whole process of deformation and instantaneous failure in two directions is required. Measurement results are effectively analyzed. The results are shown as follows: At the initial stage of loading the sandstone is in an elastic stage without macroscopic cracks. With the increase in compression load the sandstone has several small stress releases and several obvious macroscopic cracks. In the final stage of loading, the distribution of normal stress and shear stress are almost the same, and cracks are subjected to the coupling effect of normal stress and shear stress. The two ends of the prefabricated hole perpendicular to the applied load direction are prone to cracks parallel to the applied load direction. Full article

Abstract

Constant use over a period damages the bridge pulling cable structure of pulling sling bridges and reduces their durability. Therefore, a comprehensive and accurate durability evaluation of in-service bridge cable-stayed structures is critical to the safe operation and routine maintenance and repair of pulling sling bridges. In this paper, we first establish a three-layered pulling sling durability evaluation index system and then use the combined IAHP and CRITIC methods to assign weights to these evaluation indexes. The UM theory is applied to calculate a comprehensive multi-index evaluation vector for the durability of the pulling sling, which is evaluated according to the confidence criterion. Taking the Jiahui Bridge tension sling as an example, a durability evaluation was carried out, and the final evaluation result showed the bridge to be at level III, which is in line with the actual situation of the project. Finally, by comparing and analyzing using the SPA and MEE methods, we prove that the durability evaluation results of bridge tension cables using this method are more accurate. Full article
