Torsional balance of plan-asymmetric structures with frictional dampers: analytical results
(WILEY, 2005)
This investigation deals with the torsional balance of the earthquake response and design of elastic asymmetric structures with frictional dampers. Plan asymmetry leads to an uneven lateral deformation demand among structural ...
Characteristics of the double-torsion test to determine the R-curve of ceramic materials
(2006-10-01)
Double-torsion tests were carried out on a commercial ceramic floor tile to verify whether this test is suitable for determining the R-curve of ceramics. The instantaneous crack length was obtained by means of compliance ...

Torsional balance as new design criterion for asymmetric structures with energy dissipation devices
(WILEY, 2009)
Lateral-torsional coupling in asymmetric-plan buildings leads to correlated translations and rotations of the building plan, which generate uneven distributions of deformation demand among resisting planes. The deformation ...
Cyclic and Torsional Fatigue Resistance of Reciprocating Single Files Manufactured by Different Nickel-titanium Alloys
(Elsevier B.V., 2017-07-01)
Introduction: The aim of this study was to evaluate the cyclic and torsional fatigue resistance of the following reciprocating single-file systems: ProDesign R 25.06 (Easy Equipamentos Odontologicos, Belo Horizonte, Brazil), ...
Flexibility and Torsional Strength of ProTaper and ProTaper Universal Rotary Instruments Assessed by Mechanical Tests
(Elsevier B.V., 2009-01-01)
The purpose of this study was to assess how the geometric and dimensional changes made on ProTaper Universal (PTU) instruments in comparison with ProTaper (PT) instruments affected their flexibility and torsional strength. ...

Estimation of accidental torsion effects for seismic design of buildings
(1995)
A procedure is developed for including the effects of accidental torsion in seismic design of buildings. It has four steps. First, the ratio between the fundamental frequencies of uncoupled torsional and lateral motions ...
Torsional balance of plan asymmetric structures with viscoelastic dampers
(ELSEVIER SCI LTD, 2007)
This investigation deals with the torsional balance of elastic asymmetric structures with viscoelastic dampers. Plan asymmetry leads to an uneven lateral deformation demand among structural members and to unbalanced designs ...
