为了揭示木-混凝土组合结构梁桥整体受力性能,设计、制作了8 m×3.5 m木-混凝土组合(TCC)简支梁全桥模型。通过有限元数值分析和模型试验,得到了正常使用荷载作用下的荷载-滑移曲线、荷载-挠度曲线和跨中截面应变分布。结果表明:数值分析与全桥试验数据吻合良好,木梁与混凝土翼板能很好地协同工作。

In order to study the overall mechanical behavior of Timber-Concrete Composite ( TCC) beam bridge, a simple supported TCC beam bridge (8 m ×3.5 m) was designed and constructed .With the numerical analysis by finite element method and tests in laboratory , the load-slip curves, the load-deflection curves and the strain distribution across the mid-span beam were obtained under the service load .The experimental data for real bridge structure were in good agreement with the theoretical results .The resarlts showed tha...
