Frame-masonry horizontal hybrid structure is a new type of self-built residence in the rural areas
of Fujian Province in recent years. A shaking table test for 1/2 scale model is carried out on the basis of one
representative rural structure, and the dynamic characteristics and seismic responses of this experimental model
are measured. As a supplement, the finite element model of the prototype structure is built by ANSYS software,
and simulation and test results are contrasted and analyzed. The results show that according to this structure,
the beam-column joint of the frame part has stress concentration and the destruction pattern of the masonry part
is similar to brick-masonry structure. There are obvious differences in lateral stiffness of each floor and direction,
and the mass center does not coincide with the stiffness center, which can lead to excessive torsion and story
drift of this structure under earthquakes of a certain intensity. Because of poor construction quality, unfavorable
structural measures and irrational structural system in present rural areas, there is a potential safety threat with
this type of structures in highly seismic region. Some suggestions for strengthening and retrofitting frame-masonry
horizontal hybrid structures are pointed out.
