摘要

本文研究了考虑剪切变形影响的部分组合梁的界面挠度。梁系统由两个棱柱形截面的梁组成，由非常薄且刚性的粘合剂连接，承受均匀的弯矩和均匀分布的负载。由考虑剪切变形的总泛函能得到部分组合梁的控制微分方程。极限弯矩产生第二弯矩，剪力和法向力应用于每根梁。推导了微分方程，并与忽略剪切变形的部分组合梁的微分方程进行了比较。结果表明，有剪切变形和无剪切变形时挠度的理论结果相互比较，并与Timoshenko梁理论的结果相比较。

Deflection of a Partially Composite Beam Considering the Effect of Shear Deformation

In this research, the deflection in the interface of a partially composite beam considering the effect of shear deformation is deter-mined. The system of beams is structured by two beams of prismatic sections, connected by an adhesive very thin and rigid, subjected to a uniform bending moment and a uniformly distributed load. The governing differential equation of the partially composite beam is obtained from the total functional energy that takes into consideration the shear deformation. The extreme moments creating second moments, shear forces and normal forces are applied to each beam. The differential equation is derived and then, compared to the one found in partial composite beams where the shear deformation is neglected. It is shown that the theoretical results of deflection with and without shear deformation are compared to each other and also with those found in the Timoshenko’s beam theory.

期刊介绍： Periodica Polytechnica Civil Engineering is a peer reviewed scientific journal published by the Faculty of Civil Engineering of the Budapest University of Technology and Economics. It was founded in 1957. Publication frequency: quarterly. Periodica Polytechnica Civil Engineering publishes both research and application oriented papers, in the area of civil engineering. The main scope of the journal is to publish original research articles in the wide field of civil engineering, including geodesy and surveying, construction materials and engineering geology, photogrammetry and geoinformatics, geotechnics, structural engineering, architectural engineering, structural mechanics, highway and railway engineering, hydraulic and water resources engineering, sanitary and environmental engineering, engineering optimisation and history of civil engineering. The journal is abstracted by several international databases, see the main page.
