Torção de peças de seção aberta com hastes de paredes delgadas de concreto armado
… Reinforced Concrete subject to solicitation of Torsion, defering the mechanic behavior of thin-walled pieces due to Saint-Venant's and warping torsion. A quick explanation of development of the last three decades about torsion of pieces of reinforced concrete has been realized. The detailed …

TORSION THEORIES BESIDE THE POINT -- HOMOTOPICAL AND TWO-DIMENSIONAL APPROACHES
This thesis investigates the notion of torsion theory beyond the classical pointed setting, that is, in categories which need not have a zero object. Introduced in the context of abelian categories, with torsion and torsion-free abelian groups being a motivating example, torsion theories are by now …

Numerical Modeling and Analysis of Composite Beam Structures Subjected to Torsional Loading
Torsion of cylindrical shafts has long been a basic subject in the classical theory of elasticity. In 1998 Swanson proposed a theoretical solution for the torsion problem of laminated composites. He adopted the traditional formulation of the torsion problem based on Saint Venant's torsion theory. …

On the theory of Krull rings and injective modules
… two notions important to our treatment of KRULL theory. The first is injective modules and.the second torsion theories. We then look at injective modules over Noetherian rings as in MATLIS [1958] and then over KRULL rings as in BECK [1971]. We show that for a KRULL ring there is a torsion theory …

Finite element formulation of a thin-walled beam with improved response to warping restraint
Linear elastic theory of torsion and flexure of thin-walled beams as developed by Vlasov and Timoshenko respectively are well known and commonly used in everyday engineering practice. However there are noticeable differences between calculations and experimental results. The difference is partly …

A CATEGORICAL-ALGEBRAIC EXPLORATION OF MODELS FOR MANY-VALUED LOGIC
… that this pair of subcategories defines a pretorsion theory, which is the generalization to a non-pointed context of the classical notion of torsion theory. We study the Galois structure associated with the reflection of semisimple MV-algebras, proving that it is admissible from the point of …

The finite element analysis of thin-walled box spine-beam bridges
… finite element technique and the thin-walled beamtheory, which is appropriate for design purposes, has been proposed. This approach is specially suitable for medium and long spans. It is intended to be a realistic and versatile method to be used during the preliminary analysis and design stage, …

Local coherence of hearts in the derived category of a commutative ring
Approximation theory is a fundamental tool in order to study the representation theory of a ring R. Roughly speaking, it consists in determining suitable additive or abelian subcategories of the whole module category Mod-R with nice enough functorial properties. For example, torsion theory is a …
