Investigation of dynamic P-Δ effect on ductility factor

Structural Engineering and Mechanics, 2001
Current seismic design provisions allow structures to deform into inelastic range during design level earthquakes since the chance to meet such event is quite rare. For this purpose, design base shear is defined in current seismic design provisions as the value of elastic seismic shear force divided by strength reduction factor, R ().

Equivalent ductility factors, taking into account low‐cycle fatigue

Earthquake Engineering & Structural Dynamics, 1992
AbstractDuring strong earthquakes, the deformation capacity of structures is reduced due to the cumulative damage caused by cyclic load reversals. In the paper, equivalent (reduced) ductility factors have been proposed, which take into account this effect. They are based on different failure hypotheses.

The ductility reduction factor in the seismic design of buildings

Earthquake Engineering & Structural Dynamics, 1998
This paper presents new trends in the relationship between the ductility reduction factor and the ductility demand in the seismic design of buildings. A total of 4860 inelastic time-history analyses were carried out to study this relationship using 60 single-degree-of-freedom models excited by an ensemble of 81 earthquake accelerogram records from ...

Ductility in Timber Structures: Investigations on Over-Strength Factors

2014
This paper presents a study on the implementation of connection ductility in timber structures. Regardless for which purpose ductility in timber structures is needed, it is necessary to avoid a brittle failure of the timber element before the ductile element is in the stage of yielding.

The factors affecting the corrosion of ductile cast iron

The ability to reduce the corrosion of ductile cast iron pipe material is imperative, as it is widely used within many drinking water distribution systems. Reducing ductile cast iron corrosion can diminish the amount of iron particles released into drinking water.
