A low-cycle loading experiment for two specimens of symmetric double short-pier shear wall was carried out, and the failure pattern, hysteretic response, and the effect of integrative coefficient on the elastoplastic performances were studied.

The loading capability increases with the increase of integrative coefficient while the ductility decreases on condition that the number of stories, story height, dimension of piers, material and reinforcement are the same.

The research results show that the mechanic properties of short-pier shear walls are the same as the combined shear walls and if the integrative coefficient α is increasing,the lateral stiffness and the bearing capacity will be getting up but the ductility and energy dissipation will be going down.

Results indicate that with the increase of the integrative coefficient, the periods of top two modes apparently decrease but the other periods of higher frequency modes show little variation when the pier strength coefficient remains constant.

Similarly, if the integrative coefficient is constant, the top two periods of the free vibration decrease with the increase of the integrative coefficient but the other periods of higher frequency modes show less variation.

A low-cycle loading experiment for two specimens of symmetric double short-pier shear wall was carried out, and the failure pattern, hysteretic response, and the effect of integrative coefficient on the elastoplastic performances were studied. The results indicated that short-pier shear wall is a type of coupled wall with strong piers and weak beams; the beams yield earlier than piers, and moreover, the material capacity of the coupling beams may be fully used because of the internal stress redistribution in the beams after their yielding. Therefore, the short pier shear wall structures have well ductility and ability of energy dispassion. The loading capability increases with the increase of integrative coefficient while the ductility decreases on condition that the number of stories, story height, dimension of piers, material and reinforcement are the same.

The equations of the lateral deflection curve of the short pier shear wall under a lateral concentrated load at any level are derived by employing a continuous approach. Lateral flexibility matrixes for the dynamic analysis are also obtained by repeatedly calculating the lateral unit load on the wall at each level where a lumped mass located. Dynamic analyses are implemented for short pier shear walls with different parameters, called the integrative coefficient and the pier strength coefficient...

The equations of the lateral deflection curve of the short pier shear wall under a lateral concentrated load at any level are derived by employing a continuous approach. Lateral flexibility matrixes for the dynamic analysis are also obtained by repeatedly calculating the lateral unit load on the wall at each level where a lumped mass located. Dynamic analyses are implemented for short pier shear walls with different parameters, called the integrative coefficient and the pier strength coefficient related to the dimensions of walls. The influences of two coefficients on the dynamic performances of the structure are studied. Results indicate that with the increase of the integrative coefficient, the periods of top two modes apparently decrease but the other periods of higher frequency modes show little variation when the pier strength coefficient remains constant. Similarly, if the integrative coefficient is constant, the top two periods of the free vibration decrease with the increase of the integrative coefficient but the other periods of higher frequency modes show less variation.
