After meddling with SOLID65 for a long time, I moved to SOLID185. With DP Concrete model, I have gained results that match closely with the experimental results (I am satisfied!). I have been trying to get displacement vs. Base Shear during the push, and have succeeded in doing so. I believe that DP Concrete does a good job on that regard.<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/913ab012-0f5d-48c8-9ee9-a9df00291459\/70c85284-0647-4cdc-9a2a-a9f4002230d8_push-1.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p>However, I now want to incorporate softening behavior into the model (I am trying to use linear HSD model: HSD6). The base shear should go down after about 75 mm. However, after using the softening parameters, the solution doesn&#8217;t go beyond the linear&nbsp;limit.
