摘要：
In order to verify the seismic performance of a 522 m high-rise structure in the 8-degree seismic intensity zone, a 1 / 40 scale structural model was design and fabricated. By means of shaking table tests, the dynamic characteristics of the structure were studied under the action of 8-degree frequent, fortified and rare earthquakes. And the deformation and damage of the structure under the actions of one-dimensional and three-dimensional earthquakes were investigated. In addition, ABAQUS software was used to carry out an elasto-plastic time history analysis of the structure under the action of 8-degree rare earthquake. The displacement response and dynamic characteristics of the structure simulated by the finite element method were compared with the shaking table test results, and the damage status and weak parts of the structure were analyzed. The results show that the structure has good stability and structural efficiency due to the double structural lateral force resisting system formed by the outer frame cylinder consisting of the mega-columns, the mega-diagonal braces and the ring belt trusses and the core of the combined steel-concrete structure. The structure does not collapse under the action of the 8-degree rare earthquake (0. 3 times of the gravitational acceleration), which well meets the performance requirement of ‘no damage under frequent earthquakes and no collapse under rare earthquakes’. © 2023 Science Press.
