Parametric Study of EWECS (Engineering Wood Encased Concrete-Steel) Composite Columns Using 3D FE Modelling

Fauzan Fauzan, Ruddy Kurniawan, Zev Al Jauhari


This paper presents analytical study on the behaviour of composite column that consist of an exterior wood panel with concrete encased steel (CES) core, hereafter referred to as Engineering Wood Encased Concrete-Steel (EWECS) composite columns. A detailed three-dimensional (3D) nonlinear finite element model is developed to study the response and predict the seismic performance of EWECS composite columns subjected to both axial and cyclic loads by using finite element program, ANSYS APDL v.14. A reference model is validated with previous test results and is used as a reference for the parametric study. The parameters considered in the study are the compressive strength of concrete and the thickness of wood panel. The analytical results obtained from the finite element analysis is able to accurately simulate the behaviour of the EWECS composite columns on experimental study. The results show that the EWECS column had excellent seismic performance. Moreover, the results of parametric study show that the thickness of wood panel has the greatest influence on the seismic behaviour of the EWECS column, with the increment of flexural capacity of 15% by addition of 10 mm thickness of wood panel. Meanwhile, the increase of concrete strength has not much influences on the flexural capacity of the EWECS columns, in which the flexural capacity of the column only increases around 3% with the increase of concrete strength from 35 to 60 MPa
