ABSTRACT

The quayside container crane (QCC) scale models for seismic simulation test on vibration tables are often high, and the model size and QCC structural size differences introduce discrepancies into the QCC model. In this investigation, discrepancies in the QCC scale model were solved using the similarity method for the sectional radius of inertia. Firstly, a governing equation for the beam section size was established. Secondly, a scale model was constructed for the shake table test, and the results were compared with the simulations. It is demonstrated that the experimental results were close to the simulations. Specifically, the acceleration, strain extreme values, and the time of occurrence were similar at different QCC points. This reveals that the shake table test of the QCC scale model can approximately reflect the prototype seismic response, which verifies the feasibility of the model design method.

摘要

用于振动台地震模拟试验的岸边集装箱起重机（QCC）比例模型往往较高，模型尺寸和QCC结构尺寸差异导致QCC模型存在差异。在本次调查中，QCC 比例模型中的差异使用惯性截面半径的相似性方法解决。首先，建立了梁截面尺寸的控制方程。其次，构建了振动台试验的比例模型，并将结果与​​模拟结果进行了比较。表明实验结果与模拟结果接近。具体而言，不同 QCC 点的加速度、应变极值和发生时间相似。这说明QCC比例模型的振动台试验可以近似反映原型地震反应，
