“…The only records found on programming hybrid beams date from 1976, 1986 and 1987. According to Abuyounest and Adeli (1987), in 1976 the author Chong studied the optimization of hybrid beams without stiffening considering the lowest optimization cost for moment and shear. In 1986, Adeli and Phan (1986) developed a software for designing welded hybrid and non-hybrid beams according to the 1980 AISC standard.…”

This article presents a study of the behavior of hybrid steel beams of I-profile cross section subjected to bending. Numerical models of finite elements were developed and validated in the ABAQUS software. In the models, lateral buckling with torsion was disregarded, since the beam will be laterally restrained, so that only local instabilities are present and thus evaluated. Analyses were divided into two stages: first, the elastic buckling analysis was carried out to obtain the critical buckling loads and the buckling modes of the beams; subsequently, analysis of the ultimate strength capacity of the beams was carried out considering residual stresses and initial imperfections. The numerical model was defined and a sensitivity study of the yield strength of the flange steel was carried out. The obtained results from the developed numerical model were satisfactory and, as expected, showed that the hybrid beams resist a greater bending moment effort when compared to their corresponding homogeneous beams.

“…Moreover, these representations are mainly applied to a static aspect in design or to a specific period in the design process, such as the representation of connections for steel beams in steel buildings that does not aim to represent any external forces applied on structures. Interactive representation systems such as MicroCAD (Adeli and Fiedorek, 1986a, 1986b; Adeli and Phan, 1986) and Kang and Miranda's mathematical model (Kang and Miranda, 2009) have been developed for design. MicroCAD combines program structures and graphical algorithms as two subsystems and has been applied to interactive design of connections in steel buildings.…”

virtual worlds have the potential to make a major impact on global design teams by providing an online place that supports distant design activities without designers being physically present. To accommodate designing in 3D virtual worlds for the architecture, engineering, and construction (AEC) domain, there is an urgent need for the development of a representation system applicable in conceptual design and multi-disciplinary design. Extended from Qualitative Archi Bond Graphs (QABGs) that are developed as qualitative unified representations for buildings, this article presents and demonstrates an interactive graphical representation for collaborative design in 3D virtual worlds. The representation supports multiple design representation subsystems and their interactions that enable designers to better facilitate design collaboration in 3D virtual worlds.

“…Design automation of one-of-a-kind engineering systems is considered a particularly challenging problem. Adeli and his associates have been working on novel design theories and computational models with four categories: (1) interactive representation systems [4,5,8]; (2) knowledge engineering [2,3,6,55,70]; (3) software engineering [7,10,24]; (4) relational databases [78].…”

Abstract. Sharing feature-based computer-aided design (CAD) models is a challenging problem that is frequently encountered among heterogeneous CAD systems. In this work, a new asymmetric strategy is presented to enrich the theory of feature-based interoperability, particularly when addressing a singular feature or singular sketch. This paper analyzes the semantic asymmetry singular feature interoperability (SA-SFI) and parameter asymmetry singular sketch interoperability (PA-SSI) in detail. We pay special attention to the problem of PA-SSI, which is universally significant in collaborative product development (CPD). The objective of PA-SSI is to develop an optimized model to exchange a singular sketch (spline) to ensure that the exchanged model both maintains high geometric fidelity and can be effectively edited in the target CAD system. The proposed method applies the estimation of distribution algorithm (EDA) to automatically solve this problem, and a Gaussian mixture model (GMM) is built according to the promising solutions. Furthermore, Hausdorff distance is adopted to calculate the fitness, and a local optimization operator is designed to enhance the global search capability of the population. Experimental results demonstrate that the proposed approach can maintain a sufficiently high geometric fidelity, and ensure that the exchanged model of the target CAD system can be parametrically edited.
