预应力钢筋（Prestressed Reinforcement）是土木工程中一种关键的建筑材料与技术，主要用于增强混凝土结构的性能。其核心原理是在混凝土浇筑前或硬化后，预先对高强度钢筋或钢束施加拉力，使混凝土在承受使用荷载前就产生压应力，从而显著提升构件的抗裂性、刚度和承载能力。

预应力（Prestressed）的含义：

prestressed reinforcement 是土木工程中的专业术语，结合“预应力”和“钢筋/加固材料”的概念，具体解释如下：
prestressed reinforcement 指通过预先施加拉应力来增强结构性能的钢筋或加固材料。其核心目的是提升结构的承载能力、减少裂缝和变形。
常见于桥梁、高层建筑等，如：
预应力混凝土的应力计算可简化为： $$ sigma{total} = sigma{pre} + sigma{load} $$ 其中，$sigma{pre}$为预应力，$sigma_{load}$为荷载应力。
