某超高层建筑局部结构模型低周反复加载试验研究
Low-Cycle Reversed Loading Test on Partial Model of a Super High-Rise Building
摘要
Abstract
The core tube shear wall plays an important role in the lateral force systems of super high-rise building structures. Many researches are focusing on the development and application of novel types of shear walls, such as combined steel plate shear wall, concrete shear wall with steel truss and concrete shear wall with concealed braces. However, there are no enough project examples such as Beijing Financial Center office building in which the three concepts mentioned above are excellently combined. Shaking table testing research was conducted due to the superelevation and application of the three key technologies. To make best use of such shaking table test model, low-cycle reversed loading test was conducted on the partial model below the first outrigger floor to study its failure patterns, deformability and responses of local regions (such as the outriggers, the external circular steel columns and the bottom of core tube walls).关键词
