In this study, according to the concept of human tendon skeletal structure, the RC framework of beams, columns and connections of Beams and column coupled with a strong spring, the beams, columns and connections of Beams and column with a flexible confinement and flexible reinforced. When the beam or column or column connection of Beams and column in the earthquake loadings deformation yield point, and then increase the stress and strain transferred from strong rubber band or a strong spring pull, so the structure of RC beams, columns and columns and connections of Beams and column that do not reach the plastic limit point and rupture. Two story building 1/5 scaled down version of reinforced concrete frame model RC lateral loading test, the test shows a connections of beams and column in the body and the pillar and beam spring constant of the spring to add the same to increase the connection of beams and column shear strain the toughness, the spring can be subjected to lateral load of theconnections of beams and column RC Frames subject to tension and pressure back to deformation and stress reduction, and rupture can be reduced, according to connections of beams and column contingency back tension and stress record judged, RC frame attached to the joints should be linked to the different spring stiffness. By the lateral displacement of the load and the frame of the P-Δ curves show that pure RC beam model P-Δ curve was linear elastic behavior trends; adds toughness strong spring of RC frame model P-Δ curve showing elasticity, plastic ity and stagnation sexual behavior of the curve, like the soil generally has a hysteretic energy dissipation effect, and so the plastic hinge without RC Frames happen too soon. Join the toughness of RC Frames strong spring by ETABS program analysis showed that the connections of beams and column strong spring can reduce the strain, the bottom frame can withstand the shear becomes larger, adding a strong spring on behalf of its underlying framework should be strengthened. By the RC model test results and stress analysis program ETABS compare add strong spring of RC frame model has the advantage of absorbing shock elimination, old and new buildings can be added to increase the seismic capacity.
