Abstract

A new hybrid structural column system called Engineering Wood Encased Concrete-Steel
(EWECS) column was developed for low and high seismic zones. Experimental studies on the seismic
behavior of EWECS columns with varying shear span to depth ratio (shear-span ratio) have been conducted
by one of the authors. To complement and validate the experimental program, finite element analysis (FEA)
on EWECS columns with varying shear-span ratio ranging 1.0 to 2.0 under constant axial and lateral cyclic
loads are summarized. This numerical analysis uses finite element program, ANSYS APDL v.14, to
investigate the structural performance of the EWECS columns, which was compared with the experimental
results. A detailed three-dimensional (3D) nonlinear FE model of three EWECS columns with varying shear-
span ratio, subjected constant axial and lateral cyclic loads are performed. The FEA results showed that the
shear-span ratio affected by the maximum shear strength and failure mode of the EWECS columns. The
maximum strength of the columns increased with decreasing shear-span ratio. The stress distribution on the
FE models represented the failure mode of the EWECS columns well. More damages on the columns were
observed with decreasing shear-span ratio. In general, good agreement between the experimental data and the
FE models output in terms of the seismic performance and failure mode was observed.
