For example, looking at the 'Plate Moments' figure above, the total Mx moment could be obtained by multiplying the given Mx force by the length of side BC (the distance from joint B to joint C). To calculate the total Mx or My on the face of an element, multiply the given value by the length of the element that is parallel to the axis of the moment. Responsible for: -managing Continuous Integration (CI) procedures for source code stability and regression testing using TeamCity CI. Mx can then be thought of as occurring on element faces that are perpendicular to the local x-axis, and the My moment occurs on faces that are perpendicular to the local y axis. Likewise, My is the moment that causes stresses in the positive y-direction on the top of the element. Mx is the moment that causes stresses in the positive x-direction on the top of the element.
all i can think of is that regardless of what orientation i tell the software to use on the orientation / rotate options section of the DRAW MEMBERS. The plate bending moments (Mx, My and Mxy) are the plate forces that induce linearly varying bending stresses through the thickness of the element. i am learning to use RISA 3d and following through the tutorials, i can not seem to get a member rotated all the parameters seems to be correct.
It makes sense now but it's a dumb way that's probably creating a lot of confusion.
