“…The primary structure is an arched truss and represents a rod system. It has an upper chord (1)(2)(3)(4)(5)(16)(17)(18)(19)(20), a lower chord (6-7-8, 21-22-23), a lattice-vertical and diagonal elements (9)(10)(11)(12)(13)(14)(15)(24)(25)(26)(27)(28)(29), support nodes (1,14), strut nodes (7,16) and loading nodes (2)(3)(4)(5)(6)(16)(17)(18)(19)(20). The slender part is a tie member-cable (30).…”

“…The system is lighter, easier to handle, robust and stiffer than a simple beam. Piyasena et al [10] studied the blast resistance of cable trusses and cable net facades under blast loading. Gao et al [11] invented unbonded prestressing tie members with self-centering connections using enhanced sliding cable elements to dissipate seismic energy in earthquakes.…”

Heuristic Optimization of a New Type of Prestressed Arched Truss

et al. 2022

This paper represents new approaches for calculating, designing, and optimizing prestressed arched trusses with a tie member. Structural systems with long spans, such as trusses, beams, frames, etc., are subjected to a considerable/substantial risk of losing load-carrying capacity because of the different types of loads used. Some traditional design methods define the values of prestressing force in the tie member and internal forces in the truss elements to avoid this load capacity loss. However, the accuracy and limits of the determination of the forces are not necessarily known. The authors offer a new type of prestressed arched truss and some new approaches in the design and calculation process to solve these disadvantages. The study’s main objectives were to design an innovative and new geometric form of prestressed arched truss, which allows the development of high-value prestressing force, to optimize a new truss for reducing self-weight, increasing load-carrying capacity compared to its analogs. The force, stiffness matrix, and simulated annealing methods were used during the study. A new advance to the optimization of prestressed arched truss suggested by the authors reduces the self-weight and improves the load capacity of the truss by 8–17%, depending on the span.

The article presents an example of a structural solution of a mesh facade installed on a public building. The types of loads that can affect the structure of such a mesh have been characterized. The course of the wire shaping process used to produce the described mesh was reported. A FEM model was developed to simulate mechanical phenomena occurring during the technological process of crimping stainless steel wire. Material model parameters have been defined. The developed model was verified in production conditions. Relations between wire-forming loads and tensile limit loads, as well as the distribution of equivalent tensile stress forced by the crimping process and internal stresses after crimping, were determined. The description of the technological process was presented in a form of a graph. The work contains the results of strength tests of wire materials and shaping tools.
