本文以作者所进行的无粘结部分预应力混凝土梁的静力和疲劳试验研究及理论分析为基础,较为全面地分析了影响无粘结部分预应力混凝土桥梁抗弯设计的主要因素,提出了一种针对无粘结部分预应力混凝土桥梁的抗弯设计准则。该设计方法比较合理,计算也很简单,容易为工程界所接受。
Based on the static and fatigue experimental research and theoretical analysis of the unbonded partially prestressed concrete beams, the paper analyzes the main factors that affect the flexural design of unbonded prestressed concrete bridges more comprehensively, A Kind of Bending Design Criterion for Unbonded Prestressed Concrete Bridges. The design method is more reasonable, the calculation is also very simple and easy for the engineering industry to accept.
