Abstract


Buckling-Restrained support due to the buckling pressure not nature , compared with ordinary support containing buckling restrained braces structure has better energy consumption . This article by means of micro- mechanical mechanism and macro-mechanical model of buckling restrained braces theoretical analysis to determine the buckling support core unit high-end physical and geometric conditions , to provide the necessary theoretical basis for the buckling restrained braces trial research . Text for a new type of buckling restrained braces , the following test study : ( 1 ) of this new type of buckling restrained braces including standard loading and cyclic loading static reciprocating test specimen . The results showed that: the elastic stiffness of the buckling restrained support standard loading test , the plastic stiffness , yield displacement , and to yield the load mechanical index is in good agreement with the theoretical value ; cyclic loading test of equivalent stiffness , energy-intensive area , as well as the most vigorously zero displacement and zero minimum displacement force and other energy-intensive indicators is very stable and meet the requirements of engineering technology ; (2) a quasi - static test plane frame containing this buckling restrained braces and pseudo static contrast with common support framework trials. The tests showed that : containing the buckling restrained braces framework of full hysteresis curve of the buckling restrained support in the framework of energy consumption significantly ; experimental results show that the buckling restrained braces can absorb most of the framework of energy consumption , thereby improving the seismic performance of the frame ; install than buckling restrained support framework and common support framework , the former can not only improve the bearing capacity of the structure , as well as a substantial increase in the energy dissipation capacity of the frame , so as to improve the seismic performance ; ( 3) containing kinds of buckling restrained braces framework structure of the shaking table test . The tests showed that : appropriate design in a smaller earthquake , buckling restrained support and the main structure to maintain flexibility , buckling restrained braces for the main structure to provide a stable , effective stiffness and strength ; moderate earthquake , buckling restrained braces can reach the yield , the main structure is still in the elastic state , buckling restrained braces for the structure to provide a stable energy dissipation capacity .
