The authors proposed the brace with which strength, remained plastic deformation capacity and energy absorption capacity can be easily evaluated under seismic loading. Proposed brace consists of slender rod and tensile connected the end with tapered washer and wedg. The wedge slides between the washer and the stand so as to prevent the looseness of brace caused by to axial plastic deformation under repeated lateral loading. To improve the plastic deformation capacity of the brace, new tensile connected the end with the tapered washer and wedge are proposed. We made an experiment with the shaking table to confirm that mechanism of non-compression brace do function well in dynamic load. We produced one story one span frames to show performance of a brace and carried out an elasticity sine wave examination, a bullet plasticity sine wave examination and an earthquake wave examination. The results and conclusion obtained from the shaking table experiment are summarized as follows: 1)Even the comparatively big displacement amplitude resists effectively horizontal load without compression power to a brace. 2) When a wedge enters, story shear hardness of a brace rises. 3) While tension acts on a brace for sinusoidal of high frequency of 12Hz, the wedge is not pushed back and grinds crackle in an original course. And mechanism of non-compression brace functions normally.
