Dear Silvia and Others, Displacement and Force Based Beam Column Elements There are some literatures on the above subject matters. But one is amazed that not even OpenSees, that is supposedly built as both stiffness and flexibility finite element based program, shows so many surprises when one simpl...

Dear Silvia and others, I wonder if you could tell me the relationship between the global forces (x or 1 direction) and the applied horizontal forces in the sustained push over and cyclic analyses. To be specific with what force do I multiply the factors (steps) given as data in the drift file after...

Dear Silvia, I'd like to study the influence of one of the constituents’ materials in an element. What comes to mind is to keep on varying the quantity of the material whose effect is to be studied in the element. Assuming the element is modeled as containing parallel materials. How can I specify th...

Dear Silvia, I would like to know if both transverse and longitudinal sections of a structural element say a column or a wall can be represented in OpenSees Ask differently, how can the horizontal reinforcements in a wall or stirrups/transverse bars in a column be accounted for in OpenSees? Are both...

This example consist of a section 96" by 16" in total. The 48" by 16" mansory wall is confined by 24" by 16" (on both sides). Some results were produced for the gravity and push over analysis. Would you consider the arguments in this attempt valid? If so why was error g...
