摘要
讨论了不同叠合方式的叠合梁的应力分析问题,得出不同材料、不同叠合方式对应力的影响规律,即叠合梁比整体梁的承载力要低,不同的叠合方式中应将弹性模量较小、峰值拉应变较大的材料放在下层以提高其抗裂性能.
The stress analysis of superposition beam of different forms is discussed. The infection law of stress under different materials and different superposition mode is educed. The conclusion is as follows： the load-carrying ability of superposition beam is lower than the whole beam. The material of less modulus of elasticity and bigger ultimate strain should be put in the under layer to advance the performance of resisted crack.
