When Looking at Service Seismic LC 0.6D - 0.7E, how do I know which Load case it is showing. My model was imported from RAM SS which had RAM frame run with all 36-E cases. Also can I model a tension only spring to find the total uplift force to see how many anchors I would need?
Yes, point and line springs (as well as columns, walls, point supports and line supports) are linear, tension and compression supports.
does RAM have point springs that are tension only?
The soil bearing results are enveloped for the rule set, or load combination reviewed. In order to see the pressure from a single concurrent load combination including lateral loads, it has to be a single combination. not a "lateral group".
Area springs are always compression-only.
