Re: Pushover curve

What exactly you want to achieve? The capacity curve does not look strange.

Re: Seismic Retrofitting

There are numerous posts in this forum regarding convegence difficulties. As a start you might want to run an eigenvalue analysis to see if the structural members are well connected with each other.

Re: Pushover curve

Such small kinks in the curve are not somethin unseen in pushover analysis, and occur due to redisitrbution of forces upon the failure of one or more members. Yuo might want to employ a bit more stringent convergence criteria, e..g decrease the displacement and rotation tolerances 10 times (e.g. fro...

Re: RC JOINTS- Shear panel modelling

Apart from Chapter 10 of ASCE 41, I am afraid I do not have any other reference. However, the details provided there, should be probably enough. In any case, is more like commonknowledge and not our 'theory' that the beam-column joints in RC buildings are generally very stiff with respect to other p...

Re: Time-Step Change

This is not something that can be explained through a support forum, which anyway all is only about the use of our programs. Some details are provided in the help of the program, but for a better understanding you need to read the details of baseline correction and filtering from a good textbook. Se...

Re: RC JOINTS- Shear panel modelling

Apparently the flexibility of the panel in shear was negligible with respect to the other two parameters. This is typically the case in beam-column joints of RC structures. We are not sure how the shear panel rotational spring can be calibrated, a quite good reference though is Chapter 10 of ASCE 41...

Re: Hyseresis Curve for Slip Shear

For steel connections the most suitable curve is the Richard_Abbott curve. The curve is employed in the verification examples for the steel joints, Ch4-joint-04.spf, Ch4-joint-05.spf and Ch4-joint-06.spf. You may also refer to the Verification Manual and the relevant publications.

Re: Time-Step Change

Can it be the effect of filtering and / or baseline correction?

Re: Unindentified String encountered in function NodetoLocation

What happens when you open the program and load the input file? Are you not able to enter the Building Modeller?
