The article describes the relevance of the design of tall buildings. A characteristic feature of high-rise buildings is preferential perception of horizontal loads under the impact of the wind flow. Therefore, the stiffness stems represent the most characteristic for high-rise construction internal vertical support structure.
Keywords: high-rise building, strength, reliability, a horizontal load, the core stiffness, trunk stiffness, the layout structure, column, frame, diaphragm stiffness
