[PROPERTIES] How to use Section for Resultant Forces
This function will enable the users to draw resultant force diagram along the member and generate a table, for the resultant forces (Fx, Fy, Fz, Mx, My, Mz) at several section-cut planes defined along the member. The section-cut plane defined using Section for Resultant Forces option can consist of plate/plane stress elements and/or beam/truss elements.
>Curved or skewed girder bridges with composite steel plate girder are frequently simulated with plate and beam elements instead of beam elements with composite section. In this case, Local Direction Force Sum function is used to obtain resultant member forces. Previously, this function just showed the resultant forces in a text / table format on the basis of section selected by the user. Force diagram along the member was not viewed by the program.
>This function will enable the user to view the force diagram along the member and generate table results for the resultant forces (Fx, Fy, Fz, Mx, My and Mz) of a section consisting of plate elements and/or beam elements.
>Results are available for Static load, Construction stage load, Settlement load, Response spectrum load and Moving Load. In case of the results in moving load analysis, concurrent forces will be used when “Normal + Concurrent Forces/Stresses” option is selected in Moving Load Analysis Control.
>The user can specify “No. of Division” for the selected structural group or elements. This option will enable the user to easily verify the member forces at every 10th point in a span.
>The concept of virtual beam which is composed of i-end and j-end virtual sections is introduced. The virtual beam will not be viewed by the user but needed to be defined to calculate resultant force diagram. Virtual section local axis can be viewed by checking on the option in Display > Property tab.
>Section cuts for which resultant forces will be calculated can be defined using structure group, element selection or polygon cutting plane.
>Various shape of bridges such as straight, curved, skewed and inclined bridges are supported for resultant force diagram. In case of curved and skewed bridge, Polygon Select mode is recommended.
