Diagonal beam reinforcing for ductile frames

Bulletin of the New Zealand Society for Earthquake Engineering, 1979
This paper describes a system of diagonal beam reinforcing for reinforced concrete ductile frame buildings in seismic areas. The development and application of the system is described with reference to the design of an 18 storey building. The proposed reinforcing system has a number of major structural advantages over conventional reinforcing ...

Seismic Performance of RC Beam-Column Connections with Continuous Rectangular Spiral Transverse Reinforcements for Low Ductility Classes

The Scientific World Journal, 2014
The seismic performance of RC columns could be significantly improved by continuous spiral reinforcement as a result of its adequate ductility and energy dissipation capacity. Due to post-earthquake brittle failure observations in beam-column connections,

Non-linear finite element analysis for the verification and parametric study of reinforced concrete beams strengthened in compression zone to improve ductility by using ABAQUS [PDF]

Engineering and Technology Journal
Ductility is an important mechanical property of concrete structures, in tensile members, as it is the property that allows the structural member to deform plastically long before the failure point.
