Concrete encased steel (CES) structure is a composite structure that has been developed to simplify the complexity of Steel Reinforced Concrete (SRC) structure construction due to the difficulty in installing the steel section and Reinforced Concrete (RC). An experimental study on seismic behavior of CES column using fiber reinforced concrete (FRC) panel has been carried out by one of the authors. To verify the test results, a numerical study using 3D nonlinear finite element (FE) model is carried out in this study. The column was modeled using solid elements and analyzed by using ANSYS commercial software. A parametric study was also conducted with parameter such as the tensile strength of FRC. The CES column using full FRC is also modeled in order to know the influence of the full FRC on the CES composite column. The numerical results show that the FE analysis accurately simulate the seismic behavior of the CES columns on the experiment. In addition, CES using FRC panel and CES using full FRC have a stable spindle shape hysteresis loops, respectively. The parametric study result shows that the increase of FRC tensile strength results in an increase of flexural capacity that is around 5% to 17% by increasing FRC tensile strength from 8 to 16 MPa.

“…Experimental and analytical studies on seismic behavior of EWECS columns have been carried out, including the parameter of double and single H-section encased steel and shear span ratio [2][3][4]. The results show that EWECS had excellent seismic behavior with a stable spindle-shaped hysteresis curve.…”

This paper explains the numerical analysis of EWECS (Engineering Wood Encased Concrete-Steel) composite columns with and without shear studs connection under constant axial and lateral cyclic loads based on the previous experiment. EWECS column is the new composite structure contains concrete encased steel (CES) core covered by a wood panel. The shear studs were used to connect between CES core and wood panel. In this study, the non-linear finite element (FE) analysis is performed by modeling the column with the 3D solid element and the friction devices of the shear studs with the two-node-link element. The results show that the hysteresis curves shape from FE analysis has similarity with those from the test data as well as on the main stiffness, ductility, and energy dissipation. The addition of shear studs increased the ductility of the EWECS column; however, it had no significant effect on the maximum flexural capacity. The wood panel had the contribution to flexural strength of the EWECS columns until large story drift, R of 5%, even though the damage of the column occurred at story drift of 4%.
