This paper presents an analytical study on the seismic behavior of composite EWECS columns which were compared with the experimental data. A moment-curvature analysis based on hysteresis models of materials was conducted to produce the response of the columns subjected to both constant axial load and lateral load reversals. The analytical results showed good agreement with the test data. Moreover, a parametric study using the same numerical model was carried out on columns using double H-section steel to examine the effects of shear-span ratio on behavior of EWECS columns. |
