The skeleton cure is obtained according to hysteretic behavior, and then use the energy method given in the SPECIFICATION OF TESTING METHODS FOR EARTHQUAKERESISTANT BUILDING, so as to determine the initial yield load Qwty and yield displacement δy. Meanwhile, use the computing formula of SPSWS stiffness and bearing capacity proposed in 2003 by Toko Hitaka, so as to obtain the formulation values of Initial stiffness Kwt, Initial yield Qwty and ultimate bearing resistance Qwts. The results of comparison them with the test results are listed in Table 2 (The data obtained at cycle loading action in west and east direction are listed respectively).

It can be seen from table 2 that: The initial stiffness, yield bearing capacity and ultimate bearing resistance increase with the thickness increase of specimen. In which, the initial stiffness measured is smaller than the computed value from the existing formulation, the yield bearing capacity and the ultimate bearing resistance is near to the formulation value.

The ductility factor of the specimen in the test is defined as the ratio of ultimate displacement δu and yield displacement δy. Where: the ultimate displacement δu takes the corresponding displacement value when the load decreases to 0.9 times of ultimate load Pu; and the yield displacement δy is the displacement value by nomography using energy method. The ductility factors obtained by this way are shown below in table 3; meanwhile the dissipation energy Coefficient E and the equivalent viscous damping coefficient he are also shown below in table 3. (The data obtained at cycle loading action in west and east directions are listed respectively).
