In this article, a new method of increasing the efficiency combined steel roof trusses is proposed and considered. A rational shape truss, including its topology geometric parameters, was obtained, but without obtaining SSS. provides adjustment SSS in truss by changing upper belt panel length. On basis obtained structural form proposed. It shown that thanks to method, it possible obtain more ef...

Recent developments in Artificial Neural Networks (ANNs) have opened up new possibilities in the domain of inverse problems. For inverse problems like structural identification of large structures (such as bridges) where in situ measured data are expected to be imprecise and often incomplete, ANNs may hold greater promise. This study presents a method for estimating the damage intensities of jo...

In this paper, architectural constructions composed of spatial truss units are considered by using a new technique of artificial life. Such spatial truss structure has flexibility and adaptability to environments. At first, equilateral tetrahedral (regular tetrahedral) units, which are basic space units having three dimensions, are proliferated to specified directions at random. At every prolif...

Theoretical studies have indicated that truss core panels with a tetragonal topology support bending and compression loads at lower weight than competing concepts. The goal of this study is to validate this prediction by implementing an experimental protocol that probes the key mechanical characteristics while addressing node eccentricity and structural robustness. For this purpose, panels have...

A geometry-based rigorous approach to the detection of global and internal mobility of skeletal structures (trusses and frames) is presented. The method is useful for automated design of skeletal structures at the conceptual stage where the overall topology of the structure is known, but no exact detail on geometry and size is available. Such topologies are, for example, those generated by inte...

Design optimization of a class of plane trusses called the N-Shaped Truss (NST) is addressed. The parametric model of NST presented is intended for real-world application, avoiding simplifications of the design details that compromise the applicability. The model, which includes twenty-seven discrete variables concerning topology, configuration and sizing of the truss, presents a challenging op...

Truss optimization problem has been vastly studied during the past 30 years and many different methods have been proposed for this problem. Even though most of these methods assume that the design variables are continuously valued, in reality, the design variables of optimization problems such as cross-sectional areas are discretely valued. In this paper, an improved hill climbing and an improv...

This paper presents a description of a continuous truss footbridge comprising two spans, one of 140 m and the other 50 m. The bridge crosses the Sant Adria Marina, close to Barcelona. The width of the deck is 6 m and the depth of the two trusses, which form the bridge, range between 6 and 10 m. Main innovations are the use of recycled aggregates for concrete in the approach slab deck, the use o...
