Ductility of RC beams under torsion

Engineering Structures, 2018
Abstract In this article, the torsional ductility of reinforced concrete (RC) beams with rectangular cross section is studied. For this, the experimental results of several RC beams found in the literature were compiled and analyzed. A torsional ductility index was used to characterize the torsional ductility of the studied beams.

Ductile End Connections for Glulam Beams

Structural Engineering International, 2008
Ductility, which is the capability of a structure to deform significantly beyond the elastic limit without brittle failure, is a fundamental property which can be an important requirement in many i...

System ductility and redundancy of FRP beam structures with ductile adhesive joints

Composites Part B: Engineering, 2005
This paper reports on a structural concept for engineering structures composed of FRP components to provide system ductility that compensates for the lack of material ductility inherent to FRP materials. The concept includes the use of redundant structural systems and ductile or flexible adhesive joints.

Flexural ductility design of high‐strength concrete beams

The Structural Design of Tall and Special Buildings, 2011
SUMMARYIn the seismic design of a reinforced concrete (RC) structure, it is necessary to provide not only sufficient strength, but also adequate flexural ductility. This is particularly important to the design of RC beams cast of high‐strength concrete that is inherently more brittle. Eurocode EN1998‐1 directly specifies such minimum flexural ductility.

Strength and Ductility of Embedded Steel Composite Coupling Beams

Advances in Structural Engineering, 2003
The stringent requirements on dimensions, ductility, energy absorption, strength and stiffness of coupling beams have resulted in much research on various alternative coupling beam designs, which include the use of diagonal reinforcement, rhombic arrangement of main bars and steel composites.

Ductility of Heavily Reinforced Concrete Beams

2017
The overall depth of concrete structures is mostly limited due to boundaries coming from architecture or technical installations. On the other hand, there exists from the same side a demand for larger spans which requests higher span/depth ratios. A combination of high strength concrete and high reinforcement ratios for the longitudinal reinforcement ...

The achievement of ductility in reinforced concrete beams

Magazine of Concrete Research, 1998
A review is presented of the influence of lateral confinement by stirrups, longitudinal strain gradient, size effects, concrete strength and nature of loading on the strength and ductility of rectangular reinforced concrete beams. Factors influencing the strain-weakening slope of the stress–strain curve for concrete in flexural compression and the ...

Two Nonlinear Beams With Definitions of Ductility

Journal of the Structural Division, 1969
TWO MATHEMATICAL MODELS OF NONLINEAR BEAMS WHICH CAN BE USED TO REPRESENT THE GIRDERS AND COLUMNS OF A NONLINEAR MULTISTORY STRUCTURE ARE DESCRIBED AND COMPARED. ONE BEAM MODEL IS LIMITED TO BILINEAR BENDING MOMENT-END ROTATION HYSTERETIC CHARACTERISTICS. THE OTHER MODEL CAN HAVE DIFFERENT CURVILINEAR AND BILINEAR HYSTERETIC CHARACTERISTICS AT EACH END.

CROSS-SECTION BEHAVIOUR AND DUCTILITY IN COMPOSITE BEAMS.

Proceedings of the Institution of Civil Engineers, 1979
Ductility in cross-section behaviour is a necessary requirement for plastic design. It is also a desirable condition in all design since ductile structures give warning of impending collapse. The chief aim of this paper is to define the conditions required for a composite beam to exhibit ductile sagging behaviour.

Deflection and ductility of continuous RC beams

Magazine of Concrete Research, 1993
Recent research work by the Author in the fields of deflection and ductility of reinforced concrete beams has shown that in design-oriented procedures both these aspects can be controlled through effective depth-linked requirements. The present study compares the required effective depth to meet a specified deflection limit with the effective depth ...
