# 两端固支叠合梁的应力分析与实验研究Stress Analysis and Experimental Research for a Two-End Fixed Laminated Beam

Abstract: The bending stress distributions of two ends-constrained free and complete plying-up laminated beams at a mid-span and cross-sections adjacent to a fixed end, which are made of two different kinds of steel and aluminum materials, are investigated by means of electrical logging experiment technology. The simplified models of the above two laminated beams are put forward and the corresponding maximum normal stress formulae are presented. The theoretical results are compared with the electrical logging ones. The results show that the present calculation formulae are suitable for the estimation of bending normal stresses for the two end constrained beams.
