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： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
