摘要
对在役空间网架结构的承载性态及技术性能的正确评价，是确定其在后继生命历程中安全工作的主要理论依据。本文建立考虑材料应变强化效应的钢杆件空间受力模型为基础，提出了跟踪在役空间钢网架结构承载性态的分析方法，为合理评估、维护及加固这类结构提供了可靠的理论基础及计算方法。
In this paper, based on three dimension load carrying model of steel truss thinking nonlinear character of steel, the analyzed metod of follwing up load carrying behavior of the steel truss in service is given. The reliant theory and calculating method are provided for evaluating maintaining and reinforcing the steel stucture.
