Abstract

Several stiffened plates arrangements subjected to bending were configured applying the Constructal Design Method (CDM) and solved by Finite Element Method (FEM), aiming through the Exhaustive Search (ES) technique analyze the influence of transverse I-Shaped or T-Shaped stiffeners in mechanical behavior. Considering a non-stiffened plate as reference and maintaining the total steel volume constant, a portion of the reference plate was deducted from its thickness, and transformed into stiffeners through the ???? volume fraction parameter, which represents the ratio between the steel volume of the stiffeners and the steel volume of the reference plate. Assuming ???? = 0.3, 25 plates with just I-Shaped stiffeners in longitudinal and transverse directions and 25 plates with I-Shaped stiffeners in longitudinal direction and T-Shaped stiffeners in transverse direction were proposed. The results showed that the plates with transverse T-Shaped stiffeners are more effective, reducing the maximum von Mises stress and maximum deflection, respectively, in up to more than 60% and 50% when compared with the plates with just I-Shaped stiffeners.

横向加劲i型或t型加劲板受弯结构的几何分析

采用结构设计方法(CDM)配置了几种受弯加劲板布置，并采用有限元法(FEM)进行了求解，目的是通过穷举搜索(ES)技术分析横向i型或t型加劲板对受力性能的影响。以非加筋板为基准，在保持钢材总体积不变的情况下，从基准板的厚度中扣除一部分，通过????转换为加筋板体积分数参数，表示加强筋的钢体积与基准板的钢体积之比。假设? ?= 0.3，纵、横向仅加i型加筋板25块，纵、横向加i型加筋板25块。结果表明:横向加劲t型板与仅加劲i型板相比，最大von Mises应力和最大挠度分别降低了60%和50%以上;
