内容简介

钢-混组合梁是一种由混凝土板与钢梁通过抗剪连接件组合而成能整体受力的结构形式，因其广泛应用于高速铁路桥梁建设中而显得其动力性能分析十分重要。但是目前钢-混组合梁的动力分析理论的基本假定尚不明确，致使考虑参数过多而计算效率低下或考虑参数过少而计算精确不够。本书围绕钢-混组合梁的动力分析理论问题，对界面相对滑移、剪切变形和转动惯量以及相关结构和材料影响因素进行研究。主要内容如下: (1) 完善了钢-混组合梁动力分析的基本理论假定。考虑界面相对滑移、剪切变形和转动惯量的影响，推导了钢-混组合梁的运动微分方程。给出了典型边界条件下，求解钢-混组合梁动力特性的解析方法。明确了钢-混组合梁动力分析时需要考虑剪切变形和界面相对滑移的影响，但是可忽略转动惯量的影响。最终总结提出了更加适用于钢-混组合梁动力分析的Shear组合梁理论。 (2) 提出了分析钢-混组合梁动力性能的解析方法。基于Shear组合梁理论，提出了钢-混组合连续梁的动力分析方法；推导得到了钢-混组合梁的振型正交条件，进一步利用振型正交性和振型叠加法推导了动力荷载作用下钢-混组合梁的动力响应解析解。特别给出了移动集中力作用下简支钢-混组合梁的动力响应解析表达式。 (3) 探究了钢-混组合梁动力性能的相关影响因素。采用数值算例，全面分析了组合梁的结构和材料参数对其动力性能的影响。提出了与剪力键刚度有关的无量纲的截面组合连接系数α*=KL2/EA，给出了不需考虑界面相对滑移影响的α*界限值。以简支钢-混组合梁自振频率解析表达式为基础，提出了其他典型边界条件下钢-混组合梁自振频率的近似解析表达式，用于工程中快速的计算组合梁的自振频率。分析了钢-混组合梁各构件的动力放大系数及其参数影响规律。 (4) 实现了Shear组合梁理论和相关解析方法在高速铁路钢-混组合梁桥动力分析中的应用。建立了钢-混组合梁的车桥耦合分析模型，并采用全过程迭代法进行求解，其中桥梁子系统响应由本文提出的Shear组合梁理论和相关解析方法求解。分析了一座高速铁路钢-混组合梁桥的动力性能，结果表明剪切变形在钢-混组合梁桥动力分析中不可忽略；钢-混组合梁动力分析时需同时注重剪力键的动力性能分析。
