We propose a computational model for the evaluation of the service life of fiber-reinforced concrete structural elements subjected to long-term tension. The model is based on the first law of thermodynamics and a proposed idealized tensile stress-strain diagram of fibrous concrete. This model is used for the evaluation of the service life of a fiber-reinforced concrete plate containing a circular hole under the conditions of long-term bilateral tension.

纤维混凝土结构长期静载荷下使用寿命评价计算模型

我们提出了一种计算模型，用于评估承受长期拉力的纤维增强混凝土结构元件的使用寿命。该模型基于热力学第一定律和建议的纤维混凝土理想化拉伸应力-应变图。该模型用于评价含圆孔的纤维混凝土板在长期双边拉力条件下的使用寿命。
