In accordance with the characters of composite masonry structure building supported by frame shear wall with wide bay at bottom, a sub-structure pseudo-dynamiC test was carried out. When the lateral rigidity was measured before pseudo-dynamic test, the influenc.e upon structure behavior by wide bay at hottom was discovered. The test shows that the composite masonry structure supported by frame shear wall with wide bay at bottom has good aseismic behavior.
