The near-fault pulse-type ground motion may bring about excessive deformation of base isolation layer.The isolation bearings will buckle and the isolation system will be destroyed. Eleven kinds of U-shaped steel plate and I-shaped lead rod displacement reslraint devices were designed and tested.A 3-story base isolation frame model was made of steel and the shaking table model tests were carried out under near-field pulse-type ground motion.The test results show that:（1）The U-shaped steel plate limiting devices has favorable elastic properties under the static loading test;（2）The combined limiting devices have smaller residual deformation under dynamic test

but still have better capacity of limiting and restoring deformation;（3）The base isolation layer obtains desired results of soft limiting deformation under near-fault ground motion

meanwhile the storey deformation of upper structure can be controlled within the allowed range.
