<t>I don't believe that plate type elements are available in SeismoStruct at this time. A reinforced concrete wall section could still be modelled either as a column-type member between 2 nodes or, more likely, as an infill element defined by the 4 perimeter nodes.<br/> <br/> It sounds as though the...

<t>It would be of great value to users of SeismoMatch if alternate scaling routines could be added, not to replace the existing wavelets algorithm, but to provide other scaling approaches found in some modern codes. Specifically, it would be great if one could:<br/> <br/> 1. Scale two orthogonal com...

<t>Research has demonstrated that ignoring the bi-directional interaction in isolation systems (such as LRB and FPS bearings) results in over-estimation of forces transmitted to the structure and under-estimation of displacements. (See, for example, "Performance Estimates for Seismically Isolated Br...

<t>You can search the phrase 'chord rotations' in teh help file and you will get 6 hits. Select 'Member action effects'.<br/> <br/> Or from the help Contents, select the follwong:<br/> Running an analysis and processing the results<br/> Post-processor<br/> Member action effects<br/> <br/> Then read ...

<r>I am sending 7 time histories. When I do simultaneous matching for all 7 I get the error. When I do "BhujH1" by itself I also get the error. I have not yet tried any of the other files by themselves. The files have been sent to <EMAIL email="support@seismosoft.com">support@seismosoft.com</EMAIL> ...

<t>I believe that the output for rotational deformation is chord rotation in units of radians. So it is actually neither a local rotation nor a curvature. This is my understanding of the output from reading the help system.<br/> <br/> Best of luck with your work, mohamad reza.<br/> <br/> (If I am wr...

<t>If I understand correctly, you have something like a tapered column, the cross sectional dimensions of which change along the length of the member. If so,I believe you will have to discretize the taper and use prismatic elements.<br/> <br/> I believe you will have to subdivide the column into ele...

<t>You should be able to get the hysteresis depending upon where the nonlinear behavior is occuring.<br/> <br/> If the nonlinear behavior is in the frame elements, then in the Post-Processor select the following:<br/> <br/> 'Element Action Effects' tab<br/> 'Frame Hysteretic Curves'<br/> <br/> If th...
