稳定性是钢结构教学的重点和难点,配合土木工程专业钢结构基本原理课程的教学,同济大学在国内率先构建了钢结构多功能教学实验平台,将理论教学与实验教学有机的结合。钢梁整体稳定实验是观赏性较强的教学实验,然而,数年的教学实验结果表明:原钢梁夹支支座会导致整体稳定承载力偏高,从而影响教学效果。为了准确模拟钢梁的约束条件,文章对原有支座进行了改进,使实验结果更加接近理论值,收到了良好的教学效果。

Stability is the key and difficult point in steel structure teaching. As a supplement of he basic principle of steel structures course in civil engineering, Tongji University took the lead ill building a multi- functional teaching experiment platform for steel structures in China, which combines theoretical teaching with laboratory practice. Experiment for overall stability of steel beam is one of the most ornamental experiment. However, teaching experimental results in the past few years showed that overall stability bearing capacity were higher than theoretical values because of support of beam, which had a negative effect to teaching. In order to simulate boundary conditions of steel beam accurately, the author improved the support, making the experimental values closer to the theoretical values and thus achieving good teaching effect.
