摘要
为了准确计算叠合梁在荷载作用下的受力、位移,基于弹性力学基本思想和接触理论推导了考虑剪切滑移效应的叠合梁的有限元解。利用该有限元解计算了集中荷载作用下的叠合梁挠度和交界面剪切滑移,并与试验结果进行了对比分析,结果表明:有限元解与试验结果能够较好地吻合,彼此具有较强的相关性,验证了有限元解的准确性和可靠性,为分析叠合梁受力和变形提供了新的计算手段,具有较高的实际推广价值。
In order to accurately calculate the stress and displacement of composite beam under load,based on the elastic mechanics and contact theory,the finite element solution of the beam is derived,in which the effect of shear slip is considered.Using the finite element solution,the deflection and interface shear slip under concentrated loads are calculated.The calculation results are in good agreement with experimental results,which verifies the accuracy and reliability of the finite element solution.This finite element solution provides a new computing tool to analyze the stress and deformation of composite beams with shear slip.
