Abstract
The nonlinear analysis which is performed to provide a
realistic prediction of the inelastic response of reinforced
concrete structures during strong earthquake motions requires
the knowledge of the inelastic response of their individual
members or their sections under cyclic load reversals. The
available tools for this purpose are mathematical models
which attempt to describe the inelastic force-deformation
relationship considering either the whole member as a unit or
its critical sections. Models of the second category generally
provide better results. One of the fundamental parameters of
these models is the knowledge of the cross-section Bounding
Surface shape and size which is defined as the geometrical
locus of points in the space of the normal actions N, M_y, M_z
which correspond to ultimate strength. In this paper a new.
computer graphics based algorithm is presented for the
formation of the full shape and size of the Bounding Surface
of U-shaped column or shear wall elements.
