Mixed Formulation Beam Finite Element

The development of reliable analytical models is
essential for the advance of performance-based
earthquake engineering in the design of new
structures and in the seismic condition assessment of
existing structures.
This book describes the formulation of a beam finite
element model for the analysis of shear critical
steel and reinforced concrete (RC) structural members
under monotonic and cyclic loading conditions. The
element is based on a mixed formulation with three
independent fields and exhibits numerical stability
and robustness under cyclic loading conditions. The
validity of the proposed beam element is confirmed by
correlation studies of its nonlinear response with
experimental results from steel shear links, slender
RC beams and columns, and RC shear walls of moderate
to low span to depth. The model proves capable of
representing very accurately the global response, the
failure mode, and several local response measures of
each specimen. The efficiency of the element
formulation makes it suitable for the seismic
response analysis of large structural systems.
