The response of an infinite Timoshenko beam subjected to a harmonic moving load based on the third-order shear deformation theory (TSDT) is studied. The beam is made of laminated composite, and located on a Pasternak viscoelastic foundation. By using the principle of total minimum potential energy, the governing partial differential equations of motion are obtained. The solution is directed to compute the deflection and bending moment distribution along the length of the beam. Also, the effects of two types of composite materials, stiffness and shear layer viscosity coefficients of foundation, velocity and frequency of the moving load over the beam response are studied. In order to demonstrate the accuracy of the present method, the results TSDT are compared with the previously obtained results based on first-order shear deformation theory, with which good agreements are observed.

大跨度预制钢-混凝土空心板组合梁(CBHCS)是一种新型的楼板结构,可用于各种大跨度结构。然而,人为引起的振动会对此类结构的使用产生影响。为了减轻振动,需要探究由人引起的步行力与楼板状态之间的关系。本文首先使用测力板获取了25 名测试者的150 个步行力,确定了单步行走的傅里叶级数中的动态载荷系数和相位角。其次,对7 个CBHCS试样进行了行走测试,获取了模态振型、固有频率、阻尼比和加速度等基本动态特性。CBHCS楼板系统通常表现出高频(>10 Hz)和低阻尼(阻尼比低于2%)的特性。本文还使用有限元方法进行了灵敏度研究,以研究CBHCS楼板系统的振动性能,考虑了楼板厚度、
钢梁类型、接触时间和人体重量。最后,本文推导了基频和峰值加速度的解析表达式,与实验结果吻合较好,具有实际的应用价值。

In view of China’s development trend of green building and building industrialization, based on the emerging requirements of the structural engineering community, the development and proposition of novel resource-saving high-performance steel-concrete composite structural systems with adequate safety and durability has become a kernel development trend in structural engineering. This paper provides a state of the art review of China’s cutting-edge research and technologies in steel-concrete composite structures in recent years, including the building engineering, the bridge engineering and the special engineering. This paper summarizes the technical principles and applications of the long-span bi-directional composite structures, the long-span composite transfer structures, the comprehensive crack control technique based on uplift-restricted and slip-permitted (URSP) connectors, the steel plate concrete composite (SPCC) strengthen technique, and the innovative composite joints. By improving and revising traditional structure types, the comprehensive superiority of steel-concrete composite structures is well elicited. The research results also indicate that the high-performance steel-concrete composite structures have a promising popularizing prospect in the future.
