高性能钢材特点及其在建筑领域的全生命周期经济贡献研究

Research on Characteristics of High Performance Steel and Its Economic Contribution to the Whole Life-Cycle in the Construction Field

摘要: 为了提升建筑的安全性、经济性以及满足建筑外观的造型要求，建筑业对于新型钢结构的性能需求也变得多样化。高性能钢材在屈服强度、抗拉强度、断后伸长率，冲击性能、超声检测、断面收缩率等方面具有明显优势，能满足不同应用环境下对高强、抗震、耐蚀性、耐火耐低温性等多方面的需求。本文在经济性、绿色转型与可持续发展等方面进行分析，并对建筑的全生命周期内货币成本、人力成本与社会效益等方面进行探讨。

Abstract: In order to improve the safety and economy of buildings and meet the modeling requirements of building appearance, the performance requirements of the construction industry for new steel structures have also become diversified. High-performance steel has obvious advantages in yield strength, tensile strength, elongation after fracture, impact performance, ultrasonic testing, and reduction of area. It can meet the requirements of high strength, earthquake resistance, corrosion resistance, fire and low-temperature resistance under different application environments and many other needs. This paper analyzes the aspects of economical efficiency, green transformation and sustainable development, and discusses the currency cost, human cost and social benefits in the whole life cycle of the building.
