Abstract:
The behavior of composite column that consists of an exterior wood panel with concrete encased steel (CES) core, hereafter referred to as Engineering Wood Encased Concrete-Steel (EWECS) composite columns, is investigated. Nonlinear analysis is done by using finite element software, ANSYS APDL, to study the seismic performance of the columns. Verification of the finite element modeling is done by comparing and corresponding experimental result that reported by one of the authors, then it is used as a reference for parametric study. The parameters in the parametric study are the use of fiber reinforced concrete (FRC), the use of Indonesian wood and the use of friction element. The results are presented in the form of hysteresis characteristics, failure mode, and principal stress distribution. It is demonstrated that the seismic performance of the EWECS composite columns can be accurately predicted by proposing finite element modeling. Obtained results from the parametric study show that various FRC, different wood, and the contact element influences the hysteresis loops and behavior of the columns. The flexural capacity of the columns is improved about 7-17% by adding steel fiber. In addition, the typical Indonesian wood (Matoa) enhances the flexural strength about 3.3%. Moreover, the use of a friction element affects the seismic behavior significantly.
