“…En muchos casos, las placas están expuestas a cargas externas que producen deformaciones, esfuerzos y se pueden producir fallas mecánicas, por tanto, es necesario realizar diseños adecuados de las estructuras que utilizan éste tipo de placas planas, para determinar con precisión aspectos como: resistencia a esfuerzos, uso eficiente, características de comportamiento bajo cargas, deformación o pandeo de la placa. (Ventsel y Krauthammer, 2001;Sadrnejad et al, 2009;Mohtaram et al, 2012).…”

En este estudio se desarrolla y valida un modelo para simular numéricamente los esfuerzos normales y cortantes inducidos sobre las caras superior e inferior de una placa plana rectangular e isotrópica. La placa está apoyada en sus cuatro bordes y la presión es uniformemente distribuida sobre toda su área. Las soluciones analíticas se hallaron por medio de la ecuación general de placas utilizando el método series dobles de Fourier. Las soluciones numéricas se obtuvieron por el método de elementos finitos (software ANSYS 19.1). La validación del modelo se realiza comparando estadísticamente las soluciones analíticas y numéricas de los esfuerzos inducidos en un experimento clásico con tres niveles de presión. Los resultados muestran que no hay diferencia estadística significativa entre los dos tipos de soluciones. Se concluye que el modelo de simulación numérica es válido.

“…As boundary conditions, the bottom of the plate is completely fixed, the out-of-plane motion and rotational degree of freedom of the top of the plate are fixed, and the coupling has in-plane translational degrees of freedom. The first buckling mode is introduced as an initial imperfection, and the amplitude is ℎ/1000 [23,24].…”

To determine the force mechanism for the steel plate shear wall with slits, the pushover analysis method was used in this study. An estimated equation for the lateral bearing capacity which considered the effect of edge stiffener was proposed. A simplified elastic-plastic analytical model for the stiffened steel slit wall composed of beam elements was presented, where the effects of edge stiffeners were taken into account. The wall-frame analysis model was established, and the geometric parameters were defined. Pushover analysis of two specimens was carried out, and the analysis was validated by comparing the results from the experiment, the shell element model, and a simplified model. The simplified model provided a good prediction of the lateral stiffness and the strength of the steel slit wall, with less than 10% error compared with the experimental results. The mutual effects of the bearing wall and the frame were also predicted correctly. In the end, the seismic performance evaluation of a steel slit wall-frame structure was presented. The results showed that the steel slit wall could prevent the beams and columns from being damaged by an earthquake and that the steel slit wall was an efficient energy dissipation component.

“…Kumar et al (2007) used the commercial package ANSYS to analyze ultimate strength of square plate with central rectangular opening along the loading direction under axial compression. Mohtaram et al (2011) studied the experimental and numerical investigation of buckling in rectangular steel plates with grooveshape cut out and clamped supported at upper and lower ends and free supported in the other ends.…”
