Obtain Wasted-energy steel plate and out-of-plane bending deformation easily occurs under horizontal displacement, so that its bearing capacity is reduced, energy-dissipating property is moved back
Change, and be difficult to set up accurate constitutive model.3. when shear plate damper is used to consume energy coupling beam shear wall structure, it is desirable to damp
Device planar dimension can not be excessive, and concentrates on the middle part of power consumption coupling beam, to ensure damper to be cut to master, and this can cause power consumption
Steel plate flakiness ratio is too small and difficulty is connected with connecting plate., can in order to improve the flat out-of-plane buckling of shear plate damper Wasted-energy steel plate
With in Wasted-energy steel plate edge and centrally disposed ribbed stiffener, however set up after ribbed stiffener the yield force for causing damper, bearing capacity and
The key parameters such as initial stiffness are difficult to estimate, and make damper designs difficult, in addition, ribbed stiffener is connected with Wasted-energy steel plate using welding
Connect, and the destruction of weld seam can also be taken place along too early by welding not only making complexity, substantially reduce the fatigue life of damper.
Therefore, exploitation is a kind of not only can effectively eliminate membrane stress, can also suppress the flat out-of-plane buckling of Wasted-energy steel plate, stagnant
Performance stabilization, new shear plate damper simple in construction are returned, for reducing vibratory response of the structure under earthquake, structure is prevented
Main component destruction has important practical significance.
