Special Issue Information

Dear Colleagues,

Solid mechanics is a fundamental discipline within civil engineering that focuses on the behavior of solid materials under various conditions. It encompasses the study of how solid materials deform, bear loads, and fail, providing crucial insights for designing and constructing safe, efficient, and durable structures. By analyzing stress, strain, and the properties of solid materials, civil engineers can predict how structures like buildings, slopes, and dams will respond to external pressures. The aim of this Special Issue is to publish original research papers that advance the field of solid mechanics in civil engineering. Topics of interest include, but are not limited to, the following areas:

(1) The development of advanced computational models on solid mechanics;

(2) Experimental studies that provide new insights into material performance;

(3) Application of solid mechanics in structural design.

Abstract
The soil slopes in nature are normally unsaturated, heterogeneous, and even carry cracks.

The soil slopes in nature are normally unsaturated, heterogeneous, and even carry cracks. In order to assess the stability of slope with crack under steady unsaturated flow and non-uniform conditions, this work proposes a novel discretization-based method to generate the rotational failure mechanism in the context of the kinematic limit analysis. A point-to-point strategy is used to generate the potential failure surface of the failure mechanism. The failure surface consists of a series of log-spiral segments instead of linear segments employed in previous studies. Two kinds of cracks—open cracks and formation cracks—are considered in the stability analysis. The maximum depth of the vertical crack is modified by considering the effect of the unsaturated properties of soils. According to the work–energy balance equation, the explicit expression about the slope factor safety for different crack types is obtained, which is formulated as a multivariate nonlinear optimization problem optimized by an intelligent optimization algorithm. Numerical results for different unsaturated parameters and non-uniform distribution of soil strength are calculated and presented in the form of graphs for potential use in practical engineering. Then, a sensitivity analysis is conducted to find more insights into the effect of unsaturation and heterogeneity on the crack slopes. Full article

In recent years, prefabricated components have been widely used in the construction of substation superstructures, while cast-in-place foundations remain the primary method for substation foundations. This paper presents and evaluates a novel prefabricated foundation design aimed at enhancing construction efficiency and load-bearing performance. The foundation features a modular design, with each module weighing only half that of a cast-in-place foundation of the same size, significantly improving construction convenience and transportation efficiency. The load-bearing performance of the foundation was validated through static load tests and finite element modeling. The results indicate that the foundation demonstrates excellent ductility, with flexural failure as the primary mode, characterized by multiple cracks across the mid-span and complete yielding of longitudinal reinforcing steels. Further parametric analysis shows that increasing the plate thickness ratio (λ) improves the ultimate bearing capacity of the foundation significantly. Additionally, enlarging the cross-sectional size of the shear key or increasing the strength of the wet joint material enhances overall structural synergy, reduces local deformation, and improves load distribution efficiency. Overall, the sensitivity order of factors influencing the bearing capacity of the new prefabricated foundation is plate thickness ratio (λ) > wet joint strength > shear key cross-sectional size.

High-strength lightweight concrete (HSLC) is increasingly in demand for reducing the self-weight of concrete structures, achieved in this study using shale ceramsite aggregate. Despite its potential, HSLC has been underutilized in field projects due to concerns about its strength and long-term stability. This study investigates the impact of shale ceramsite content on the mechanical properties of HSLC through uniaxial compression, flexural, and bending tests. The results reveal that ceramsite content significantly influences the concrete’s mechanical properties and failure mechanisms. An optimal design of HSLC was proposed in this study and further used in a real field highway project, demonstrating its applicability to bridge pavements. Newly developed fiber Bragg grating sensors were installed in the material to monitor the performance of the HSLC. Concrete performance monitoring was conducted using a new type of fiber Bragg grating sensor independently developed by the research team. The results showed that the higher the ceramsite content, the greater the shrinkage deformation. And similarly, the higher the strength, the greater the shrinkage deformation. The outcome of this study would provide an alternative approach for the application of HSLC in civil infrastructures. Full article
