Structural Analysis of High-rise Buildings Under Lateral Loads

Abstract

With the advanced development of modern society, the structural analysis towards high-rise buildings becomes more and more important to ensure stability for service purposes. Foundations of high-rise buildings provide fundamental support to the structure and transfer lateral loads from the upper portion of the building to soil and deep underground sublayers. While taking multiple factors such as soil-structure interaction, foundation layout configuration, and dampers, into consideration, the foundation must resist seismic energy and prevent excessive soil settlement. Compared to different structure systems, each high-rise building has different design and construction, such as rigid-frame, diagrid frame, and shear wall structure system. Structural analysis about each of the structure systems is conducted in this paper. Structure could dissipate and absorb lateral loads using different mechanics and materials. In addition, the exterior shape would affect the stability of the structure using analysis with fluid mechanics. Finding the most suitable structure system needs collaboration between engineers to achieve the best design with highest safety factor and stability.
