This paper presents the structure design and the computing process of a high-rise building in detaiI. The building has concave trough that break through the rule of high-rise building code. Through the structure plane arrangement, elastic plate design, and the structural treatment for the upper structure,the code is satisfied.
Keywords:  concave plane; plate; torsion; period; displacements; structural construction
