“框架加固”力学创新实验方案设计与结果分析

Design and Analysis of Results of Mechanics Innovation Experiment Schemes for "Frame Reinforcement"

为了提高带孔的泡沫框架承载力,利用复合材料对正方形泡沫框架加固,提高泡沫框架在角点受荷情况下的承载力。文章对比分析了泡沫框架在不同开孔方式的情况下,不同加固材料和不同加固方式对提升框架承载力的作用,得出最优的加固方式。实验表明,利用碳纤维布进行整体加固,对提升泡沫框架的承载力效果最为明显。

The bearing capacity of the foamed frame with perforated holes is not high, and the composite foam is strengthened by the composite material to improve the bearing capacity of the foam frame at the corner. In contrast, the effect of different reinforcement materials and different reinforcement methods on the bearing capacity of the frame is analyzed in the case of different opening methods, and the optimal reinforcement method is obtained.
