A full scale masonry model of two-floor and single bay was built in this paper and was strengthened by ring-beam and constructional column. And then pseudo-dynamic testing was conducted to study the time-history curves of displacement, velocity, acceleration response and restoring force in 7 degree rarely earthquake. Results show that the earthquake performance is steady and there are no visible cracks on the model after the testing. Windows and doors perform well because of the constraint of ring-beam and column, whereas failures often occurred when the structures were not strengthened. Seismic performance is largely improved by ring-beam and constructional column and the structure can resist 7 degree rarely earthquake.
