DOI: 10.1016/j.asej.2015.08.015
Abstract: Abstract In seismic codes, the force strength reduction factor is proposed to transform elastic to inelastic strength. The ductility reduction factor, R μ , plays a key role on R factor if no overstrength is… read more here.

DOI: 10.1016/j.oceaneng.2016.12.006
Abstract: Abstract Offshore pipelines are often buried to protect the pipeline from external loads and upheaval buckling. Models for pipe uplift resistance in clay soils are based predominantly on homogenous backfill conditions. In practice, however, there… read more here.

DOI: 10.1016/j.soildyn.2016.10.002
Abstract: Abstract This paper investigates the strength reduction factor of single-degree-of-freedom (SDOF) system subjected to the mainshock–aftershock sequence-type ground motions. Both displacement ductility and cumulative damage are considered in the reduction factor. Records of mainshock-aftershock earthquakes… read more here.
