Dear Huff, Thank you very much for your kind reply. If when I check the "Peak strains and stresses" in "Post-processor", and found section a and section d occurred yielding of steel, and I would like to show the yielding on the following graph, could you please help me to check w...

Dear seismostruct support, I have a two storey two bay steel frame, and I use 4 integration sections for the beams and columns. When I run the pushover analysis for this frame, in "Post-processor", I can check the Peak strains and stresses for section a, section b, section c, and section d...

Dear Seismostruct support, I have a very basic question about the Rayleigh Damping since I am a beginner in this part. I would like to apply Rayleigh damping to a four storey three bay RC frame for dynamic time-history analysis. In Seismostruct user manual, I understand I should choose two modes. In...

Dear Zoi, Thank you very much for your kind reply. Is there a bug in v7.0.6 for mass damping? Since I have difficulty in Convergence for analysis with mass damping. If I delete mass damping or change mass damping to stiff damping, there is no convergence problem with my dynamic analysis. Could you p...

Dear Seismostruct support, I am trying to run a dynamic time-history analysis on a four storey three bay RC frame with infill panels, and I would like to add damping in the infill element. I understand there are three different damping available in SeismoStruct. When I select mass-proportional dampi...

Dear Seismosoft support, Could you suggest me how you calculate the Strut Area 1 of small infill panels (59100mm2), large infill panels (49400mm2), door infill panels (31200mm2) and complete infill panels (50100mm2) in Ch4-infill-04 of verification report? And why you define the Strut Area 2 is 20% ...

Hi seismosoft support, Could you please suggest me what is the stress (min strain) and stress (max strain)? And what does the "+" and "-" mean for the stress? In my model, the mean compressive strength of concrete is 16Mpa, and the mean tensile strength of concrete is 1.9 Mpa. No...

Dear Seismosoft support, I would like to do some dynamic analysis on Ch4-steel-1 in verification report, but it does not have mass with it, thus the results for current dynamic analysis is not reasonable. Is Seismostruct software can convert vertical load to mass? If Seismostruct can not do this, co...

Dear Seismosoft support, I am trying to calculate the Equivalent contact length-hz for infill. However, there are two parameters I would like to check with you. The help of Seismosoft describes that Em is the Elastic Modulus of the masonry, is this Em same with Initial Young modulus in Strut Curve P...

Dear Zoi, Thank you very much for your kind reply. In the reference of Nakashima M., Matsumiya T, Suita K, Liu D. [2006], I have seen in page 10 “During the first cycle in the positive loading of the 1/20 amplitude, the ‘North’ plane’s second floor beam was fractured from the beam bottom flange” and...
