“…Object-oriented methodology provides a unified method and framework for analyzing, designing, and implementing systems by simulating human way of thinking, decomposing the solution problem layer by layer, and realizing the mapping isomorphism of problem space and solution space. Object-oriented technology shows great potential and advantages in dealing with large and complex problems [28,29], which is essentially a method of analyzing, designing, and developing software systems using techniques such as objects, classes, encapsulation, and inheritance [30]. After continuous research and improvement, it has been widely employed in scientific research and engineering cases in various industries and has achieved many practical results [31][32][33].…”

The movement of rock formations caused by mining eventually leads to the mining subsidence damage of the surface. In order to accurately and efficiently predict the surface subsidence caused by mining, an object-oriented method combined with the classical probability integration method is introduced in this paper, and an object-oriented probability integration prediction model framework is established. MATLAB2019 is used to develop the application program of the prediction model, the reliability of the prediction model is tested by engineering cases, and the main influencing factors of mining subsidence are analyzed at the same time. The results show that the predicted results of the model are basically consistent with the case. The prediction model developed in this paper using the object-oriented method combined with the probability integration method is reliable. It is feasible to apply the object-oriented method to mining subsidence prediction.

“…These largescale software have been developed using object-oriented programming technology (OOP), which is currently believed to be the most promising way for designing a new finite element application [47]. The development of object-oriented engineering software flourished in the 1990s [48][49][50][51][52][53], and some new object-oriented software packages have also been developed to implement new structural analysis algorithms or to extend the capability of existing software [54][55][56][57]. With the support of abstraction, encapsulation, modularity and code reuse in OOP architecture, object-oriented finite element software, particularly those written in C++ language (such as OpenSees), have shown high performance and still provide for the maintainability and extensibility essential in modern software packages.…”

openVFIFE: An Object-Oriented Structure Analysis Platform Based on Vector Form Intrinsic Finite Element Method

The vector form intrinsic finite (VFIFE) method is a new and promising structural analysis technique that has many advantages as compared with the conventional finite element method (FEM) in analyzing the complex behaviors of a structure. However, despite the popularization of its application in civil and infrastructure engineering, there is no available unified general analysis framework for it, which limits the applications and developments of VFIFE. This work develops and implements a platform (termed openVFIFE) based on a new proposed object-oriented framework to facilitate the development and application of the vector form intrinsic finite method as well as the efficient and accurate analyses of complex behaviors for civil structures. To validate the platform, a series of numerical examples are conducted. Furthermore, to extend the applications of VFIFE, the nonlinear dynamic and collapse processes of a transmission tower under earthquake load are studied using openVFIFE. The results of these numerical examples simulated by the developed truss or beam elements are consistent with theoretical solutions, previous research or conventional finite element models. The failure modes of the transmission tower under earthquake load simulated by the platform is consistent with those observed in real cases. In addition, the results of nonlinear dynamic analyses of the transmission tower show that the computational efficiency of the proposed platform is 6-10 times higher than that of the conventional finite element method. The results provide sufficient evidence to prove the accuracy and efficiency of the proposed platform in the static, dynamic and elastoplastic analyses of truss and frame structures, especially in the structure analysis characterized by strong geometry nonlinearity. It is noteworthy that in addition to the link and beam elements, further work is undergoing on implementing more elements, such as shell and solid elements. The openVFIFE also allows researchers who are interested in this topic to put their creative ideas into this platform and continuously improve the completeness and applicability of the VFIFE method.

“…Therefore, the logic is simple and easy-to-understand and does not require a solid professional computer background and basic knowledge. Objectoriented technology has become one of the main methods of modern programming (Chen et al, 2020;Lopes et al, 2020;Lv et al, 2020;Prajapati and Chhabra, 2020;Van Hien et al, 2020). Recursion is an algorithm widely used in program design.…”

The exploitation and utilization of coal resources have caused serious ecological and environmental problems that are closely related to the movement and destruction of the overlying strata, especially the activities of the overlying key strata (KS). The existing KS calculation methods are characterized by low efficiency and high costs. This study proposes an object-oriented improved recursive algorithm (OORA) model to achieve efficient calculations for KS. An application program was developed and tested with the KS of the Xiadian coal mine, Shanxi, China. The calculation results were basically consistent with field observations, and the calculation depth was increased by 146.05 m. In addition, five typical KS calculation cases were selected for in-depth testing. The calculation time ranged from 0.175–0.225 s, and the calculation time was shortened by approximately three times compared to that with traditional methods. Therefore, it is feasible to apply the model algorithm for KS calculations, and the model provides benefits such as high efficiency and low costs.
