    How to model 2 end beams connected to columns with a middle beam (ETABS API)

    Hi. I'm trying to model a steel-frame structure using ETABS API. I want to model each beam between two columns as a 3-part component. some thing like this: When I run and analyze the model and get the results, the ratios of "Story Max Over Avg Displacements" are extremely high (about 1.7) and...

    Error in performing miStartSteelDesignCheck of Structure

    Hello everyone. I have developed a steel-frame model in ETABS 18.1.1 using API. The model works correctly. When I try to design it, using an auto-select list, the model starts to design and it seems that one iteration completes. The model re-analyze itself and start to design again, but at the...

    Modifying "Unbraced Length Ratio(Minor)" in ETABS API using python

    I have developed an ETABS model, using API with python. After designing the model, there is an error that relates to beams' unbraced length. So I need to modify "Unbraced Length Ratio (Minor)". The command that I've used, is this(unique name for beams in my model starts from 126 to 325 ): for i...

    Assign load forces to the frame objects

    Hi. I'm developing a model in ETABS using API with Python. I have created and assigned load forces like SDEAD(super dead),Ex,Ey,LRED (Reducible Live) and etc,. As you can see in the first and second picture, load forces have successfully assigned. The problem is that these loads (Created...

    EATABS API- How to modify load patterns

    Hi, I'm trying to model a steel frame building using ETABS API with python. I have defined load patterns, but I need to modify seismic loads and set Auto Lateral Load on User Coefficient and after that, modify C & K factors(Base Shear Coefficient and Building Height Exp.). I couldn't find...
