Results of an experimental study on seismic behavior of Engineering Wood Encased Concrete-Steel (EWECS) composite columns with varying shear span to depth ratios (shear-span ratios) are summarized. Three specimens were tested under constant axial load and lateral load reversals. The column cross-section was kept constant while the column height was varied to produce different shear-span ratios. The results showed that the maximum flexural strength of the columns increased with decreasing shear-span ratio. However, more damages on the columns were observed with decreasing shear-span ratio. |
