EXPERIMENTAL RESEARCH ON A CFST FRAME-RC CORE WALL STRUCTURE WITH ENERGY DISSIPATION DEVICES

摘要

A high-rise CFST frame-RC core wall building is complex high-rise mixed structure, and the energy dissipation technology was adopted. In order to investigate seismic performance of the building with dissipated devices and damping effect by different dampers arrangement schemes, the 1/35 scale model with dampers and without dampers were tested respectively on shaking table under different earthquake excitations. The model's dynamic characteristics, accelerations, displacements and strains were contrasted and analyzed, at the same time the earthquake responses of model with different arrangement schemes were researched. Results show that the CFST frame-RC core wall structure with dampers has excellent seismic performance, and the scheme 1 has better damping effect than the other two schemes.
