Effect of Load and Prospect on High-Rise Buildings

Abstract

With the acceleration of urbanization, high-rise buildings have become the most familiar buildings in the city because of many advantages such as a small footprint and good lighting. However, due to the height of high-rise buildings, they are particularly affected by transverse loads, such as wind load and earthquake load. To have a better understanding of high-rise buildings, this paper discusses the central structural systems of high-rise buildings. And explains the influence of wind load and earthquake load on high-rise buildings. The main structural styles of high-rise buildings include frame structure, shear wall structure, frame-shear wall structure, and tube structure. Frame structure weight of small but large displacement, shear wall structure integrity but less space, frame - shear wall structure is the advantage of the two, and frame tube structure has strong ability to resist lateral but considerable weight. The randomness of wind load leads to unstable vibration of high-rise buildings. The weakest link of high-rise buildings under seismic load appears at the beam-column joints. Future high-rise buildings will pay more attention to humanistic significance while considering safety. This paper summarizes the advantages and disadvantages of several primary forms of high-rise buildings at present, and analyzes the influence of wind load and earthquake load on high-rise buildings, which has specific guiding significance for the safety research of high-rise buildings.
