• Seismic behavior of a six-story reinforced concrete building with base isolation in the City of Morelia

  J. López Pérez, J. Jara-Guerrero, H. Arias, F. Domínguez Mota, B. Olmos-Navarrete

  SMCCA (2024). 2

  
  

  Abstract

  Base isolation is currently acknowledged as an effective strategy for controlling the seismic response of buildings. However, its implementation is usually limited to buildings considered essential or vital to society, resulting in these systems being rarely regarded as a feasible structural option. This study examines the impact of a base isolation system on the seismic response of a six-story building situated in a moderately seismic zone. Parameters such as floor drift and shear force demand were assessed to quantify the seismic response. These aspects are not only associated with potential damage but also play a critical role in predicting the initial construction cost. Additionally, these parameters are used as design criteria in building codes and regulations.

• An Implicit Modified Lax-Wendroff Scheme for Irregular 2D Space Regions

  G. Tinoco Guerrero, F. Domínguez Mota, J. Tinoco-Ruiz

  IMACS Series in Computational and Applied Mathematics (2013).

  
  

  Abstract

  Nowadays, there are many modelling problems which involve the shallow water equations for irregular domains. One of the most important blocks for solving these equations is the advection equation. In this paper, we present the implementation of an implicit modified Lax-Wendroff scheme in order to approximate the solution of the advection equation in some irregular domains in the plane, using a general finite difference method on structured convex grids.

• Numerical solution of diffusion equation using a method of lines and generalized finite differences

  G. Tinoco Guerrero, F. Domínguez Mota, J. Guzmán Torres, J. Tinoco-Ruiz

  Rev. int. métodos numér. cálc. diseño ing. (2022). Vol. 38, (2), 24

  
  

  Abstract

  One of the greatest challenges in the area of applied mathematics continues to be the design of numerical methods capable of approximating the solution of partial differential equations quickly and accurately. One of the most important equations, due to the hydraulic and transport applications it has, and the large number of difficulties that it usually presents when solving it numerically is the Diffusion Equation.   In the present work, a Method of Lines applied to the numerical solution of the said equation in irregular regions is presented using a scheme of Generalized Finite Differences. The second-order finite difference method uses a central node and 8 neighbor points in order to address the spatial approximation. A series of tests and numerical results are presented, which show the accuracy of the proposed method.

• A numerical approximation for build the stress/strain diagram with just the maximum load obtained

  J. Guzmán Torres, F. Domínguez Mota, G. Tinoco Guerrero

  SMCCA (2020). 2

  
  

  Abstract

  One of the fundamental features in the design of rigid pavements is the rupture modulus, which value is obtained experimentally using a bending test and indicates the maximum load that a concrete beam can support. To determine this value is expensive and impractical since the tests require rather large stress values, there is always a risk of producing brittle fractures in the probes used. For this reason, it is proposed in this paper an implementation of a numerical estimation for the deformations due to the maximum load through a simple interpolation model that allows the generation of the stress/strain diagram using the only data available: the maximum load. The results show that it is possible to calculate the maximum deformation value in the beam previous to the failure. Also, it is possible to generate the stress/strain diagram and distinguish the elastic and elastoplastic areas of the concrete.

• Numerical Solution of Advection Equations Using Structured Grids on Plane Irregular Regions With a Finite Differences Scheme

  G. Tinoco Guerrero, F. Domínguez Mota, J. Tinoco-Ruiz

  SMCCA (2015). 20

  
  

  Abstract

  Today we faced the problem of solving equations for shallow bodies of water in irregular regions; These equations are very important to be able to model the behavior of liquids that have the characteristic that their extension is much greater than their depth. One of the important blocks to solve these equations is the advection equation. In this work, some schemes are proposed to approximate the solution of the advection equation in irregular regions in the plane, using a variation of the finite difference method in convex and structured meshes.

  Abstract

  Las inundaciones y desbordamientos de canales son fenómenos que han venido afectando a la sociedad por muchos años; estos se han incrementado debido a lluvias atípicas provocadas por el cambio climático. Para prevenir las afectaciones es conveniente mejorar nuestra comprensión del fenómeno, el cual está descrito por ecuaciones como las de Saint-Venant. En este trabajo se muestra una alternativa a aproximar numéricamente la solución de tales ecuaciones en dominios como canales.

• Generalized finite difference solution for the Motz Problem

  C. Chávez, F. Domínguez Mota, S. Lucas-Martinez, J. Tinoco-Ruiz, D. Santana Quinteros

  Rev. int. métodos numér. cálc. diseño ing. (2021). Vol. 37, (1), 13

  
  

  Abstract

  In this paper, it is presented a formulation of a generalized finite difference scheme to solve the Motz problem. It is based on a general difference scheme defined by an optimality condition, which has been developed to solve Poisson-like equations whose domains are approximated by a wide variety of grids over general regions. Numerical examples showing second-order accuracy of the calculated solutions are presented.

• A Generalized Finite Difference-Volume Hybrid Method Applied to Shallow-Water Equations

  G. Tinoco Guerrero, F. Domínguez Mota, J. Tinoco-Ruiz, J. Martínez, N. Tinoco-Guerrero, M. Leppäranta, I. Mammarella

  Revista Mexicana de Métodos Numéricos (2020). Vol. 4, 2

  
  

  Abstract

  Due to the importance of the shallow-water equations in models of real-life phenomena, in recent years the study and model of problems that involve them have been the object of interest of many people. By reason of this, it is imperative to have efficient numerical methods to obtain an approximation of the solutions of the shallow-water equations. Several authors have worked in approximations using the well-known finite volume and finite element methods, nevertheless, even when these methods compute good approximations to real-life behavior, the computational cost is usually high, which could be a limitation to the application of these methods. This paper presents an explicit Generalized Finite Difference-Volume Hybrid approximation to the solution of the shallow-water equations, solved on irregular regions meshed with logically rectangular grids; the numerical results show the accuracy obtained with a low-cost implementation. The proposed scheme is a hybridization of a generalized finite difference scheme with the finite volume method.

• Cálculo de daño en pavimentos mediante un análisis hidro-mecánico de pavimentos flexibles

  C. Chávez, F. Domínguez Mota, M. Hernandez-Peña, E. Arreygue

  Revista Mexicana de Métodos Numéricos (2020). Vol. 4, 1

  
  

  Abstract

  A hydro-mechanical analysis of a pavement is presented in which the variation of the water content is considered for the estimation of modulus of elasticity of the layers of soil in the pavement. To do this, the Richards differential equation and equilibrium in the axi-symmetric condition are solved simultaneously, considering a non-linear elasticity that depends on the suction and stress state in the soil. With this type of analysis, it is possible to quantify the variation of the damage with respect to time and visualize the deterioration of the pavement structures. It is considered a practical case in which the increase in damage is quantified in function of the variation of environmental conditions and conclusions are obtained.
