- Abstract
A project is a complex over-limit high-rise building in Foshan, including a 145.9 m high tower A and a 103.7 m high tower B, they are all using frame-core wall structure. On the 96.6 m high, tower A and tower B are connected by a steel structure corridor with a span of 18.5~28.3 m, and the connection nodes are constructed by setting up lead-core rubber bearings. The structures have irregularities such as torsion irregular, sudden changes in stiffness, multiple towers and complex connections. According to the predefined performance objectives, multiple softwares are used to carry out elastic design, checking design under fortification earthquakes and elastic-plastic dynamic time-history analysis under rare earthquakes. The calculation results show that the structure is completely elastic under small earthquakes, all indicators meet the requirements of the code under moderate and rare earthquakes, and the structure can reach the seismic performance target C. According to the calculation and analysis results and the conceptual design method, targeted strengthening measures have been taken for key and important components to ensure the bearing capacity and ductility of the structure under earthquake, and ensure the safety and rationality of the structure.
