The application of a steel plate damper with honeycomb-shaped openings (honeycomb damper) to various portions of buildings is desirable. This study was undertaken in order to obtain the restoring force characteristics and energy absorption capacity of the honeycomb damper subjected to horizontal shear load under initial axial force or out-of-plane deflection. Six full-scale specimens were cyclically loaded with increasing displacement amplitude. The test parameter were initial axial force (maximum ratio of applied axial strain to axial yield strain was 200 %) and out-of-plane deflection (3 mm was selected). It was found that initial axial force and out-of-plane deflection had no influence on the restoring force characteristics or energy absorption capacity of the damper. The yield strength of the damper decreased to some extent, however. Therefore, it was confirmed that the honeycomb damper can be used where there is initial axial strain and out-of-plane deflection, at least for the range of values tested. Furthermore the analytical modelization of hysteresis characterristics of the damper was tried.
