摘 要

伴随社会的进步，人们生活水平不得不断提高，对建筑要求也越来越高，尤其是高层建筑和大跨度建筑。钢材所具有的的强度高、塑性好、自重轻、施工便捷、抗震能力强等各方面的优点，能够满足高层以及超高层，大跨度以及超大跨度建筑的要求，是这些建筑的理想材料。总而言之，不管是在国内还是国外钢结构将会在未来的建设中扮演主要的角色，它任然会是建筑行业的主流。

Abstract

With the progress of society, people living standards have to improve, the construction requirements are getting higher and higher, especially high-rise buildings and large-span buildings. The steel has the advantages of high strength, good plasticity, light weight, convenient construction, strong earthquake resistance and other aspects, to meet the high-level and high-rise, large span and large span of the building requirements, is the ideal building materials. All in all, whether it is in the domestic or foreign steel structure will play a major role in the future construction, it will be the mainstream of the construction industry.

Keywords: steel structure, office building, structural design
