Abstract

Authors had proposed the brace that 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 end with tapered washer and wedge. There is no buckling in the brace. The wedge slides between washer and stand so as to prevent the looseness of brace due to axial plastic deformation under repeated lateral loading. To improve the plastic deformation capacity of the brace, new tensile connected end with tapered washer and wedge are proposed. To show the mechanism and performance of the brace, the repeated lateral loading tests are performed on one story one bay frame with tensile connected brace with wedge device. Results and conclusion obtained from loading tests are summarized as follows. 1) The perfectly elasto-plastic hysteresis are observed until slide displacement of wedge reaches its maximum value. 2) Story shear, strength and energy absorption capacity are easily evaluated. 3) The remained plastic deformation capacity after earthquake can be evaluated by means of checking total slide displacement of the wedge. 4) Using new tensile connected end with tapered washer and wedge, it is possible to enhance the plastic deformation capacity.
