Re: Pushover analysis issue while using joint2d element

Hi,

I solved it and get the some preliminary results in the pushover analysis.

I am curious to know about your modeling issues and pushover response. Do you get the correct time period?

I am glad to communicate with you to discuss and keep updating.

Re: Problem with series material in joint2D element

Dear Dr. Frank, Thank you for your quick response. I use the following script for running pushover analysis. ------------------------------------------------------------------------------------- # Pushover Analysis # if {$analysisType == "pushover"} { puts "Running Pushover..." set lat2 [expr 0.125*...

Pushover analysis issue while using joint2d element

Hi Eveyone, When I model a simple one story frame with joint2d element for the beam column joint considering five uniaxial elastic materials, and elastic beam and column elements, I got the reasonable time period performing eigen analysis after having run the gravity analysis. However, I got the fol...

Re: Why my IDA curve is linear?

Hi, To perform IDA analysis, the model should carefully incorporate the following issues: 1. selection of appropriate material nonlinear model 2. P-Delta effects for geometric non-linearity with leaning column 3. Suitable algorithm for dynamic analysis and solution convergence 4. Interval of time st...

2-Story Moment Frame with Panel Zones and RBS Result

I found the different time period and floor displacement response when I check the following website to perform dynamic analysis for two story moment resisting frame with panel zones. http://opensees.berkeley.edu/wiki/index.php/Pushover_and_Dynamic_Analyses_of_2-Story_Moment_Frame_with_Panel_Zones_a...

Re: We are collecting OPENSEES User-Requirements Data

I need following information for modeling and getting results for nonlinear analysis: 1. Some examples of base isolation system such as rubber bearing, friction pendulum or others. 2. Easy Identification of formation of hinge locations in frame structures in order of developing these hinges in the f...

Re: Failed Convergence Test

When I analyzed Dynamic Analysis of 2-Story Moment Frame available in http://opensees.berkeley.edu/wiki/index.php/Dynamic_Analysis_of_2-Story_Moment_Frame. I got the following warning: Failed to converge. Then, although I modified the convergence tolerance limit to lower values and increase the numb...
