| 摘 要： | 分析了跨高比、加载方式对预应力混凝土梁抗弯强度和结构性能的影响．利用平面梁弯曲理论导出单元切线刚度矩阵，提出了新的分析模型可用于预测预应力混凝土梁从开始加载直至失效的非线性全过程响应，并利用建立的分析模型详细评估了跨高比及加载方式等参数对预应力混凝土梁的弯曲强度和受力性能的影响．

| Abstract: | This paper explores how the span-to-depth ratio and load type are correlated to the prestressed concrete beams.The nonlinear plane beam element theory is adopted to derive the element tangent stiffness matrix.The proposed model is capable of predicting the nonlinear full-range response of prestressed concrete beams from initial prestressing up to failure.Some important parameters are studied using the proposed approach,including the span-to-depth ratio and load type. |

| Keywords: | prestressed concrete beam span-to-depth ratio load type |
