【摘要】 随着现代建筑楼板结构向轻柔、大跨度、装配式方向发展，楼板体系的舒适度问题越发凸显。为了评价大型钢骨架节能轻质装配式复合板舒适度特性，利用共振原理，采用偏心激振器对大型钢骨架装配式复合板进行周期性动力加载试验，测定复合楼板损伤前后的自振频率、峰值加速度、阻尼比等动力特性。试验结果表明，新型复合板的舒适度满足相关规范要求。最后，建立有限元分析模型，对复合板进行振动分析。计算结果表明，有限元自振频率计算结果与实测值吻合较好，可为装配式复合板的推广应用提供依据和参考。更多还原

【Abstract】 With the development of modern building floor structures towards lighteweight, large-span, and prefabricated construction, the comfort of floor systems has become increasingly prominent. To evaluate the comfort performance of a novel prefabricated steel-framed composite panel, a periodic dynamic loading test was conducted using an eccentric vibration exciter based on the resonance principle. Dynamic characteristics, including natural frequency, peak acceleration, and damping ratio, were measured for the panel in both undamaged and damaged states. The experimental results showed that the comfort level of the panel met the requirements of relevant specifications. Finally, a finite element model was established to analyze the panel’s vibration behavior. The calculated natural frequencies from the model showed good agreement with the measured values, providing a basis and reference for the promotion and application of this composite panel.更多还原
