摘要
为探究不锈钢复合钢板结构的减碳前景,本文分析了"双碳"战略背景下钢结构行业的发展趋势,包括智能建造快速发展、新兴产业提供广阔市场以及高性能钢材和高性能结构发展更为迅猛,指出不锈钢复合钢板结构可兼顾高性能、经济性以及减碳要求.基于全寿命周期评价理论,采用排放因子法,提出了不锈钢复合钢板结构的碳排放计算方法.结果表明:不锈钢复合钢板结构的全寿命周期碳排放量比钢结构少36％,比不锈钢结构少10％.用不锈钢复合钢板结构替代普通钢结构,可以有效减少碳排放;替代不锈钢结构可以在减碳的同时具有良好的经济性.
Abstract
In order to explore the carbon emission reduction prospects for stainless-clad bimetallic steel structures,this paper analyzes the development trend of the steel structure industry under the carbon peak and carbon neutrality goals.These trends include the rapid development of intelligent construction,the broad market provided by emerging industries and the accelerated development of high-performance steel and high-performance structures.This paper highlights that stainless-clad bimetallic steel structures can meet the requirements of high performance,economic efficiency and carbon emission reduction.Based on the theory of life cycle assessment,a carbon emission calculation model for stainless-clad bimetallic steel structure was proposed by using emission factor method.The calculation results showed that the carbon emission of stainless-clad bimetallic steel structure was 36％less than that of steel structures and 10％less than that of stainless-steel structures.Replacing ordinary steel structures with stainless-clad bimetallic steel structures can effectively reduce carbon emissions.Replacing stainless-steel structure can reduce carbon emission and achieve economic efficiency.
