Investigation of the Distribution of Cumulative Ductility Demand Parameter in Various Stories of Buckling Restrained Braced Frames [PDF]
Journal of Rehabilitation in Civil Engineering, 2019 Attributable to the fact that the buckling-restrained brace core yields both in tension and compression, it can absorb energy and exhibit high ductility rendering it proper in order to tolerate earthquick loads..

Preliminary analytical study on seismic ductility demand of wood diaphragms [PDF]
Advances in Structural Engineering, 2016 A new seismic design methodology is being proposed for floor diaphragms for various types of construction materials including wood diaphragms. The new design methodology introduces a design acceleration to keep diaphragm elastic under design-basis earthquake using a mode superposition method.

A Superelastic Retrofitting Method for Mitigating the Effects of Seismic Excitations on Irregular Bridges [PDF]
Civil Engineering Infrastructures Journal, 2018 Irregularities in bridge pier stiffness concentrate the ductility demand on short piers; while not operating on the longer and more flexible ones. The existence of non-uniform, ductility demand distribution in bridges significantly influences seismic ...
