Abstract:The Gangwan plaza locates at the side of the Pearl River in Guangzhou. Its main tower consists of 27 stories, and the total height is 99.9 meter. The key technical problems are presented, including excavation protection, extra-long basement without temperature joints, structural system of main tower and its analysis, typical CFST joint’ analysis and experiment. The solution to unique but unfavorable aseismic architectural scheme, and the joint with non-through-core CFST connection, which is applying for patent, are introduced in details.
