<r>I've prepared a simple model of a frame to perform a eigenvalue analysis but when I apply nodal constraints to it, response parameters are very desultory.<br/>
when I remove nodal constraints the results are acceptable.<br/>
I need to apply diaphragm to model for more coplicated analysis and this ...

<t>I want to model a symmetric 3d steel structure including 5 frame in one direction that 3 of them are not moment resisting.<br/>
to perform an IDA analysis I want to simplify model in 2d model so I nead to put gravity loads in two separate form that first acts just as gravity and second one will ...

<r>I implemented an IDA anaysis .<br/>
in postprocessing menu/ida envelopes all cases are normal and accepteable but element forces and deformations<br/>
all elements are in form of 'FBPH'<br/>
element forces are extremely large and element relative displacements are all zero!<br/>
I checked my ...

<r>hello seismostruct !<br/>
I found an ucexpected error to report<br/>
i made 2 model similre to each other just with difference in defintion of diaphragms in story levels<br/>
in one model master node is in corner of storey<br/>
and in other model master node is in middle of story<br/>
resulting ...

<t>Hi,<br/>
I'm to provide my disertation in earthquke loaing field<br/>
me and my friends are trying different softwares to perform exact and userfriend softs.<br/>
there is some questions about seismosoft:<br/>
1. when we model a simple frame model like using wizard, buckling is considered by ...
