概况

该方向包括两个主要部分：钢筋混凝土和预应力混凝土构件的耐火性能，以及氯离子引起的钢筋锈蚀及其防护。大部分成果将试验与数值模型相结合，发表于Construction and Building Materials、Cement and Concrete Composites、Engineering Structures和Structures等期刊[6, 9, 11, 15]。

主要研究主题

火灾下的空心板、柱与桥梁主梁

对大厚度预应力空心板在火灾和高温下的抗剪性能以及钢纤维对挤压成型空心板耐火极限的影响进行了研究[5, 6, 7]。有限元温度场模型表明，在碳氢火灾下先张法I形梁的初始抗弯承载力最多损失51%，而后张法梁在前90分钟内保持稳定[19]。依据俄罗斯标准SP 468在越南条件下计算了钢筋混凝土柱的耐火极限，并研究了混凝土爆裂对受约束柱中温度致压力的影响[13, 20]。

钢筋锈蚀与锈胀开裂

研究了钢筋混凝土板中钢筋在不同腐蚀环境、干湿交替和不同氯离子含量下的微电池与宏电池腐蚀[12, 15, 16]。解析和数值模型描述了钢筋周围不均匀、多峰值的锈层以及从起始阶段到裂缝扩展阶段的混凝土锈胀开裂[8, 10, 11, 14]。对局部修补钢筋混凝土板采用牺牲锌阳极的阴极保护进行了试验，并优化了阳极布置[21, 23]。

桥梁剩余寿命

对Long Biên桥（1899—1902年建成）河内一侧的前六跨进行了数值建模，并通过几何测量进行修正，以评估剩余寿命并支持养护计划[18]。

发展方向

以下方向依据2023—2026年的论文、科研课题以及教师简介中列出的研究方向归纳；本页不涉及规划或经费。

  1. 预应力桥梁主梁的火后评估

    2026年的一篇论文通过室内试验和现场评估量化了火损梁的预应力损失，延续了2025年关于碳氢火灾下I形梁的论文[19, 24]。

  2. 修补结构的阴极保护

    2025—2026年关于牺牲锌阳极的两篇论文，使锈蚀研究从建模转向防护措施[21, 23]。
