Brief Tutorial on MDSolids for Beam Analysis

Brief Tutorial on MDSolids for Beam Analysis

1. Open MDSolids. Note Help tab on left and Modules tab on right of window.

2. Define the cross-section:
a) Click on "Section Properties" icon.
b) From the menu bar, choose the type of cross-section you want (e.g., flanged).
c) Enter the dimension data (be sure to choose your units on this screen).
d) Enter the modulus (you can choose from the dropbox if you want).
e) Click "compute" and another window shows you various section geometrical properties. In this window, click either "y axis properties" or "z axis properties." Click "print" to print various information about the cross-section.
f) If needed to find properties with respect to another axis, then enter the rotation angle and click "rotate" and then click "compute."

3. Definethe beam length, BC, loads; and determine V&M deagrams plus deflection: Click "back" on the Section Properties Module window and then click "Determinate Beams" icon.
a) Choose the icon for the type of beam you want (e.g., simply supported).
b) Input length and location of supports (note units!).
c) Click "enter"
d) Click on the icon for the type of load you want.
e) Enter the location andmagnitude for the load (note units!). Click "enter."
f) Repeat for as many loads as you want.
g) When you are done with loads, click "Options" on the Beam Diagram Module window. Choose "shear/moment diagrams", "rotation/deflection diagrams", etc. To get the sign convention for shear that you want, click the +V box on the shear diagram to change direction of positive shear on right face. Again noteunits! To print either set of diagrams, press "options" and then "print."
h) Note value of shear force and bending moment that might be interest (and their locations).

4. To determine the shear stress and axial stress:
a) Click "back" on the Determinate Beam Module window.
b) Click the Flexure Module icon.
c) On the analysis tab, input the axial force, shear force and bending moment that occurs atthe cross-section (located at x) where you want to determine shear and bending stress.
d) Click the "Normal Stress" button and you will see a picture of the normal stress distribution. You can use the slider bar on the left of the stress diagram to vary the position (y) at which the shear stress is calculated. When you move the slider bar (to change y location), you have to click the stressbutton so the stress is recomputed at that location.
e) Click the "Shear Stress" button and you will see a picture of the shear stress distribution. Use the slider bar to determine shear stress at different y location from top to bottom of cross-section.

5. On almost any window, you can print your results by pressing the print button at the top of the module window. On the Beam Diagrams Modulewindow, click "Options" first, and then print.

Breve tutorial sobre MDSolids para el Análisis de la viga
1. MDSolids abiertas. Nota pestaña Ayuda en la pestaña izquierda y los módulos a la derecha de la ventana.
2. Definir la sección transversal:
a) Haga clic en el icono "Propiedades de la sección".
b) En la barra de menú, elija el tipo de sección que desee (por ejemplo, con brida).
c) Introduzca losdatos de dimensión (asegúrese de elegir las unidades de esta pantalla).
d) Introduzca el módulo (se puede elegir en el cuadro desplegable si quieres).
e) Haga clic en "calcular" y otra ventana que muestra varias secciones propiedades geométricas. En esta ventana, haga clic en "Propiedades del eje Y" o "propiedades del eje z." Haga clic en "Imprimir" para imprimir diversa información sobre lasección transversal.
f) Si es necesario para encontrar propiedades con respecto a otro eje, a continuación, introduzca el ángulo de rotación y haga clic en "rotar" y luego haga clic en "calcular".
3. Defina la longitud de la viga, BC, cargas; y determinar V & M diagramas más deflexión: Haga clic en "Atrás" en la ventana de Propiedades de la sección Module y luego haga clic en el icono "Determinadas...
