“Three Dimensional Analysis of Precast Concrete Structures for Seismic Loading”
by
Graduate Student of
Civil & Environmental Engineering
Pennsylvania State University
In this presentation,
a computer program (SNAPS-3D) being developed to perform nonlinear dynamic
analysis of three-dimensional precast concrete building structures will be
described. The finite element library consists of three-dimensional brick
elements to model wall panels and horizontal diaphragm components, beam
elements with plastic hinges to model coupling beams, and spring elements to
model behavior of joints between panels and diaphragms. The spring elements are
designed to model potential crushing, gap opening, and sliding. Of particular interest is the performance of
the joints at the interface between diaphragm and vertical wall panel elements.
Truss elements are used to model vertical post-tensioning.
