Fengqiao Bridge of China Railway Co. Ltd. Beijing China 2. China Academy of Railway Sciences Corporation Limited Institute of Standard Metrology Beijing China Abstract Post-tensioned pre-stressed simply-supported concrete box-girde is widely used in the construction of railway bridges and it is an important structure for the construction of high speed railway. A comprehensive

9 16 31 review on the state of the box-girde in high speed railway technology is given. This article discusses the structural analysis of box-girde construction technology of box-girde construction equipment of box-girde and the influence of external factors on box-girde.

Journal of Sound and Vibration Experimental Research on Dynamic Responses of Steel-Concrete Composite Beams under Harmonic Load Zhang Yanling 1 Liu Huan 1 Zhang Bo 2 1. School of Civil Engineering Shijiazhuang Tiedao University Shijiazhuang China 2. China Railway Jianan Engineering Design Institute Co. Ltd. Shijiazhuang China Abstract In order to research the dynamic response of the steel-concrete composite beam under forced oscillation taking the shear connection degree as parameter three steel-concrete composite box beams were designed and conducted dynamic experimental researches under harmonic load with different static loading components loading amplitudes and loading frequencies. The variation laws of mid-span dynamic deflection midspan acceleration and joint slip with shear connection and harmonic load characteristics were obtained. The results indicate that the mean slip value and the slip amplitude at the surface between the steel girder and concrete slab and the mid-span acceleration and dynamic deflection show a sine wave shape under the sine harmonic load which increase with the decrease of shear connection degree. The mid-span dynamic deflection and mean value of the ship are mainly affected by static load weight. The slip amplitude is mainly affected by loading amplitude while mid-span acceleration is greatly influenced by the load frequency and load amplitude.
