Abstract: The design and research of increasing floor of the government building in Shenyang include the comparison of increasing floor programs, the reinforcing design using friction dampers on the original three - story frame structure, the two 1:3 scale models of the pseudo - dynamic test, the design of the frame structure which increased two floors, checking the bearing capacity of foundation soil, calculating the settlement of foundation. The article provides the excellent example for the seismic reinforcing and the increasing floor design of frame structures.
Keywords: increasing floor; frame structure; friction damper; seismic reinforcing; pseudo-dynamic test; bearing capacity of foundation soil;  settlement of foundation
