Special Issue Information

Dear Colleagues,

With the growing demand for low-carbon, resilient, and safe infrastructure, advanced structural systems have become increasingly important in modern civil engineering. Rapid urbanization, climate change, increasing fire hazards, and the need to extend the service life of existing buildings have all accelerated research into high-performance structural materials and hybrid systems. Steel structures, steel–concrete and steel–timber composite structures, and fiber-reinforced polymer (FRP)-based composite systems offer significant potential for improving structural efficiency, sustainability, and resilience.

This Special Issue aims to provide a forum for recent advances in the behavior, design, strengthening, and fire performance of these structural systems. The topic addresses innovative structural materials, structural safety, rehabilitation, and sustainable construction technologies for the built environment.

In this Special Issue, original research articles and reviews are welcome. Research areas may include, but are not limited to, the following: steel structures; steel and concrete composite structures; steel–timber composite structures; fire performance; FRP; FRP-reinforced concrete; strengthening and retrofitting; experimental and numerical studies; durability and lifecycle performance; and design methods.

We look forward to receiving your contributions.

Ecological concrete (EC) is a promising material that offers both effective surface protection in engineering and contributes to ecological restoration. However, it remains a significant challenge to improve bending resistance and tensile strength simultaneously, particularly for slope ecological restoration, where these properties are essential. This study employs an orthogonal experimental design to evaluate the effects of various factors, including water–cement ratio, coarse aggregate, fly ash, and metakaolin on the performance of EC, with the goal of determining an optimal mix ratio that satisfies both porosity and compressive strength requirements. The results indicate that, when the water–cement ratio is 0.30, the coarse aggregate particle size is 3–6 mm, the fly ash content is 15%, and metakaolin content is 10%, the EC achieves superior performance with a compressive strength of 18.3 MPa and a porosity of 29%. Then, a flexible ecological concrete blanket (FECB) is subsequently proposed utilizing this optimized EC mix. The FECB demonstrates excellent bending performance and a tensile strength of 4.2 MPa. This innovative FECB not only expands the application potential of EC in engineering but also provides a promising solution for future slope surface protection materials. Full article
