Hello guys,
After creating the building model, I checked the model and did not get any errors.
However, when trying to create the model alive in ETABS, in the connections between the floors and the walls of the elevator shaft, stiff elements are automatically generated by the program at all the...
hello colleagues,
Let's look at the case of a roof for a residential building in the shape of a pyramid trunk, with metal beams on the contour of the faces in horizontal planes at successive levels in height and beam elements in the plane of the faces (the faces are defined as if they were a...
To create this type of body constraint, in ETABS it is relatively simple to define a flat slab containing the points located on its perimeter and assign the diaphragm behavior. The center of mass calculation is automatic. In my case, I did not intend to define a slab, but to connect the points...
hello fellows,
in ETABS program, how to create a body constraint between points on the perimeter of a flat quadrangular surface and a point in the center of mass of that surface, without resorting to modeling a slab and, therefore, ignoring the automatic calculation of the same point from a...
Once again, my sincere thanks. I understood your explanations very well. Sorry for the audacity (or annoyance), but do you know of any valuable books that you can recommend, dedicated to mathematical expressions for calculating the spring coefficients? Cordial greetings
Thank you HTURKAK for your valuable contribution. i understood the explanation YOU gave me, but I wanted to put another one. Performing the structure modeling for example, in Sap2000, how is it possible to introduce two behavior coefficients in the same analysis, for the lower and upper portion?
I have a doubt about the interpretation of clause 4.3.3.3 of EC 8, when it establishes that the sum of the effective modal mass for the modes to be considered in the modal analysis, must represent at least 90% of the total mass of the structure. I suppose that the mass of the structure referred...
Hello wrxsti,
The sketch shown in the video is the one that corresponds to my situation. Although the video is not spoken in English, I think I understand the explanation, about providing rigid links between the nodes.
Thank you for your reply.
Hello fellows,
In Etabs, how can we constraint an end joint of a beam offseted from the plan where lies a column to the top centroid joint of these column, so that the forces at the end of the beam are correctly transferred to the centroidal axis of the column?
Thanks in advance
