| Abstract: | This design scheme of RC frame shear structure system with energy dissipated brace composed of viscoelastic dampers in 9 degree seismic area is briefly introduced. The seismic designs of viscoelastic dampers and energy dissipated brace are illustrated. The calculation method of elastic plastic earthquake response and main calculation result are given. The calculated result shows that its superstructure can be designed for intensity 8 after using the viscoelastic dampers. Viscoelastic damper increases the damping ratio from 5% for the bare structure to 10% or so and results in significant reduction of the story displacement response and acceleration. Its bearing capacity and deformation can satisfy the requirements of the seismic code for both common earthquake and exceptionally serious earthquake. |
