“…Therefore, the aim of the study is to determine the effect of seismic excitation on a CSP bridge with span exceeding 17 m and a variable depth of the soil cover above the steel shell (from 1.0 to 5.0 m). The obtained results demonstrate that the depth of the soil cover has a significant impact on the response of the bridge [10].…”

Strengthening old bridges is an increasingly relevant strategy for risk prevention and operation continuity in management of infrastructures. Transportation networks are subjected to progressively stricter environmental and load conditions, leading to a growing number of deficient structures, also due to aging and deterioration. However, employable resources are finite, from both economic and environmental points of view. For these reasons, strengthening opportunities should be considered as a viable option, improving bridges with low economic and environmental impact. With this perspective, a selection of some of the most interesting strengthening techniques for old truss steel bridges is presented. To address effective solutions, the most frequent problems in old truss railway bridges are first presented. Literature analysis and experts’ interviews were conducted and compared to results obtained from a representative bridge cluster. Different solutions addressing highlighted problems are then collected and qualitatively evaluated, in terms of efficacy on structural and typical construction requirements. Finally, general remarks and recommendations based on collected evidence are presented.

“…However, the area of sustainability is very broad, which is confirmed by numerous studies on this subject. In papers [3,4], the authors contributed to the aspect of sustainable development by using a construction material in the form of a natural aggregate (backfilled sand). Thanks to this, a large span of the structure was obtained with a relatively low consumption of structural steel.…”

“…These are structures erected in accordance with the principles of sustainable development, which allow you to make savings. Approaches to sustainable development are presented in many papers; for example, by Ma et al [1], Kisku et al [2], and Embaby et al [3], as well as Maleska and Beben [4]. In the case of geodesic domes, the cost-effectiveness results from the possibility of approximating the initial face of the polyhedron to smaller ones and, consequently, obtaining straight struts with a slight variation in their length.…”

This paper presents the problem of the efficient shaping of spherical structures of geodesic domes, which is the basis for creating a regular octahedron, in the aspect of sustainable development. The proposed two methods of shaping covered by this study differ in the way the dividing points of the initial edges of the regular octahedron are connected, and, therefore, in the way the sphere is shaped. Using different methods, two families of domes with different lengths of struts but with a similar number of them were obtained. The conducted comparative analysis leads to the indication of this method of shaping the topology, thanks to which it is possible to obtain structures with less consumption of construction material, and, consequently, with less weight. Both the geometry and weight indicate the advantages of geodesic domes created using the first subdivision method. The selection of the appropriate method of shaping geodesic domes is a consequence of a sustainable design strategy. The presented structures in the form of geodesic domes, the basis of which is a regular octahedron, can be original, innovative coverings, while the detailed analysis carried out is intended to provide design guidelines that will facilitate both architects and designers.

“…Different to HRM, VRM is challenging and risky because the force of the rotating system varies due to the position change of superstructure. Finite element method (FEM) is a useful tool to simulate stress and deformation during construction process and analyze the strength and stability of various bridge components [8][9][10][11][12]. Ma et al [13] simulated the rotating structure in three dimensions of a concrete-filled steel tube concrete basket arch bridge, and the most unfavorable stress conditions were determined.…”

The vertical rotation method is a special option for steel tower construction in fabricated bridge. The tall tower is prefabricated on the ground and then pulled to its designed position using steel wires. Traditional vertical rotation method always uses a taller temporary structure to provide an upward pull force to lift the rotation member; however, the temporary structure would spend much time, cost, and work high above the ground. For instance, the Jinwu Bridge tower’s weight was so heavy that the ordinary rotating method was not feasible. Therefore, a relay traction system with two auxiliary struts was employed to rotate the tower. The chief strut was first rotated to an inclined angle of 60° by an assistant strut to decrease the lateral component force of tension. Then, the tower was pulled from horizontal to vertical by the chief strut. Furthermore, a numerical model was established to analyze the mechanical behavior of the inner force, stress, and deformation of the chief strut, assistant strut, and tower. The study identified critical conditions such as the reverse of axial force for the assistant strut, intervention of back cables, and release of cable tension. The relay traction system effectively reduced initial pulling stress, spending less cost and time. Besides, the analysis method can be an innovate reference for other vertical rotating projects.
