Re: Modelling tower

Hi camilocorrea. I looked the model over this weekend and couldn't identify any problems. I'm not sure what you are trying to simulate. But the loads are enormous. Shear failures are indicated in the performance criteria at a vertical load of about 59,000,000 pounds and the maximum attained load is ...

Re: Advtantage of Modified IMK curve of BWBN Curve

As to the advantages and disadvantages of each, I cannot fully attest. However, I believe you will find that the 'Smooth' model in SeismoStruct effectively corresponds to the BWBN model to which you refer. So both options are actually available in SeismoStruct. Best of luck in your work.

Re: Plastic hinge length

When you define the element class, you will see in the required input that the units are indeed given to be '%'.

Re: cyclic loading

It should become clear upon study of Verification Report example problems. I would suggest: Steel Frame - Example 1 (quasi-static cyclic loading example) Steel Frame - Example 2 (acceleration history cyclic loading example) There are several other examples of cyclic loading in the Verification Repor...

Re: rigid offsets

I believe that dx at node 1 would be 200 mm and dx at node 2 would be -200 mm, I believe. The graphical depiction in SeismoStruct is very useful in this regard as it shows the 'shortened' beam with both ends stopped at the column face. This assumes that the beam is indeed situated such that the glob...

Re: Need a help

At least on my installation, I do not see the coefficients until I select "Apply Baseline Correction" and hit "Refresh". Then, I see the coefficients which, as noted in the Help System, are for information only, and cannot be changed by the user. Note that for the most appropriate and timely respons...

Re: element classes

1. Inelastic frame force-based elements 2. Bi-linear links element with shear direction yield set to VP of the EBF-Link section at each end of EBF-Link; all other directions set to a value large enough that yield in that direction is never reached. This is what I plan to try. I have tried with the b...

Re: Loading phase & Applied loads

You will need to make the decision as to where the loads are to be applied. If, for example you had a three story frame and you wanted the triangular distribution you describe, then you could apply loads of 1 kip at one node of the first elevated level (or 0.5 kips at two nodes at this level, etc.),...

Re: Loading phase & Applied loads

For a simple, non-adaptive pushover with a target displacement, incremental forces with response control seem to work just fine, Ralazem. You might give this a try and see if it meets your intended modeling strategy. In the response control loading phase, just specify the node and corresponding disp...

Re: Response accelerograms cannot feature more than 200000 t

I get the same error when I open your file, EmerrsonB. To test it out, I opened a file of my own which has 30,000 points and I still get the same error message as you regarding exceeding 200,000 points. I then tried opening my file only reading 1/2 of the points (a total of 15,000 points) and still ...
