“…Part of these programs are specialized in earthquake engineering [4]- [11] and are often intended to serve as Journal of Software Engineering and Applications virtual laboratories. Many of them are restricted to simple predefined models, such as single degree-of-freedom (SDOF) and multiple degrees-of-freedom (MDOF) systems [4] [5] [6] [11] [12] [13] [14] [15], or frames defined by parametric templates [7] [8] [9] [10]. Among those that allow free modelling of frames, some rely on non-graphical inputs [16] [17] [18] [19] [20] and only a few have an interactive interface for efficient pre-and post-processing [21] [22]…”

This paper introduces a new version of the open-source educational software, LESM (Linear Elements Structure Model), developed in MATLAB for structural analysis of one-dimensional models such as frames, trusses, and grillages. The updated program includes dynamic analysis, which incorporates inertial and damping effects, time-dependent load conditions, and a transient solver with multiple time integration schemes. The software assumes small displacements and linear-elastic material behavior. The paper briefly explains the theoretical basis for these developments and the reorganization of the source code using Object-Oriented Programming (OOP). The updated Graphical User Interface (GUI) allows interactive use of dynamic analysis features and displays new results such as animations, envelope diagrams of internal forces, phase portraits, and the response of degrees-of-freedom in time and frequency domain. The new version was used in a structural dynamics course, and new assignments were elaborated to improve students' understanding of the subject.

“…The analysis of the literature shows the interest to develop more innovative and efficient teaching methodologies that ease students into understanding structural concepts (such as the dynamic behavior of structures) that are hardly perceived from just the mathematical formulations [23]. For example, many authors (such as those of [24][25][26][27]) have proposed practical activities to monitor the dynamic response of small-scale models on educational shaking tables using low-cost sensors. In fact, experiences learned in this work have proven the learning benefits of including a small-scale model analysis when teaching the dynamic response of structures.…”

In the last years, more and more studies have highlighted the advantages of complementing traditional master classes with additional activities that improve students’ learning experience. This combination of teaching techniques is specially advised in the field of structural engineering, where intuition of the structural response it is of vital importance to understand the studied concepts. This paper deals with the introduction of a new (and more encouraging) educational tool to introduce students intuitively to the dynamic response of structures excited with an educational shaking table. Most of the educational structural health monitoring systems use sensors to determine the dynamic response of the structure. The proposed tool is based on a radically different approach, as it is based on low-cost image-recognition techniques. In fact, it only requires the use of an amateur camera, a black background, and a computer. In this study, the effects of both the camera location and the image quality are also evaluated. Finally, to validate the applicability of the proposed methodology, the dynamic response of small-scale buildings with different typologies is analyzed. In addition, a series of surveys were conducted in order to evaluate the activity based on student´s satisfaction and the actual acquisition and strengthening of knowledge.

The actual open‐source hardware and software tools offer a rich set of options for developing didactic tools to improve the teaching–learning process of various areas of engineering. Using low‐cost sensors, in conjunction with free software development tools, allows the creation of educational interfaces and platforms offering very acceptable performance and precision that help the student to become familiar with the basic principles that govern professional equipment. In this work, we propose a low‐cost system for data acquisition specially designed to improve the learning experience of experimental mechanics. To achieve this purpose, we use open‐source software and hardware tools to create a piece of educational equipment that is fully configurable for different sensors. We present the experimental results of two case studies: the vibration analysis of a rotor‐bearing system using acceleration signals and a free‐vibration study using a xylophone and a low‐cost microphone. The proposed platform helps authors to complement a 4‐month course named Vibration, intended for mechanical engineering students. The students who participated in the study demonstrated an improvement in their comprehension of vibration theory and modal analysis using the finite element technique. The feedback from students indicates that 84% of the participants are highly motivated to learn more about vibrations and experimental mechanics.
