Hello, Please how does ram concept treat seismic load combinations with "E" term? For instance in the design of mat foundation, if I have ultimate seismic east Loading and ultimate seismic north loading both defined in the model, are both loadings considered independently in the seismic load combination for instance, D + 0.75L + 0.525 E. In other words are the east and north seismic loading considered independently in the "0.525E" term or both seismic directions are considered acting together? The manual is not clear about this.
