“…They efficiently obtain several architectural morphologies with both structural rationality and aesthetic rules, which lead to the exploration of design alternatives. Yu et al (2022) proposed the conceptual and aesthetical design of the pylons of cable-stayed bridges using a new form finding method, considering aesthetic rules and morphologic feature from local culture to achieve harmony between the bridge and the environment. This last work is consistent with the goal of our work but is limited to the early design phase.…”

Purpose: This paper aims to enhance the visual quality of artificial above-ground structures, like pylons, masts, and towers of infrastructures and facilities, through a systematic design method for their morphological and structural optimization.Design/methodology/approach: The method achieves the functional and aesthetic goals based on the application of computer-aided tools. In particular, this is achieved according to three key steps:• Morphological development of landscape-related symbolism, environment, or culture and social needs.• Topology optimization of the design concept to reduce the structural weight and its visual impact.• Engineering of the resulting optimized structure.Practical implications: As a case study, the method is used for designing electricity pylons for the coastal territory of a Mediterranean European country, such as Italy. Citizens were involved during the identification phase of a symbolic shape for the concept development and during the final assessment phase.Research limitations/implications: The engineering phase has been performed by assembling standard lattice components with welded connections. Even if the use of this truss-like structure should lead to a minimum cost, the developed structure employs an additional 15%–20% of trusses and sheet metal covers the final cost is higher than a standard lattice pylon.Findings: The result is a structure with enhanced visual quality according to the international guidelines and fully complying with mandatory and functional requirements, such as regulatory and industrial feasibility, as well as those arising from social components.Originality/value: The method shows its potential in defining a custom design for lightweight structures with enhanced visual quality regarding the critical situation discussed here. The method considers both the subjective perception of citizens and their priorities and the landscape where the structures will be installed.

“…According to the water leakage survey, combined with the tunnel geological environment [6], construction level, material characteristics [7], and structural form [8], the management of the water leakage problems required a comprehensive analysis to grasp the causes of leakage, the consideration of the technical feasibility and economical type, the choice of the appropriate methods, materials, and construction technology to improve the efciency and ensure the management efect. Te grouting method was the most commonly used in water leakage management due to its simple process and strong adaptability to the complex environment [9,10].…”

This paper aims to disclose the properties of the chemical grouting materials under different conditions. Firstly, the water-soluble polyurethane (WPU) slurry, oil-soluble polyurethane (OPU) slurry, epoxy resin (EP) slurry, a slurry mixed by WPU slurry, and OPU slurry marked as (WPU + OPU) slurry were selected to test the properties. The setting time, volume shrinkage, and adhesive strength were measured under room conditions and water conditions. Then, the tunnel construction joints were simulated, and the injectability and water blocking effect were analyzed to evaluate the suitability of the different grouting slurry. In addition, the results were applied in the water leakage management of the Taihu Lake tunnel project. The test results showed that each of the four materials had its performance advantages and disadvantages and provided vital guidance for the engineering application.

“…Methods include physical modeling, computational simulations, and optimization techniques. Form finding enables the creation of efficient and visually appealing structures that meet design criteria [4]. The software Rhinoceros 3D (Robert McNeel & Associates, Barcelona, Spain) with the Grasshopper plugin was employed for this purpose.…”
