You need to place &quot;FLOOR DIAPHARGM&quot; block after &quot;Reference LOAD&quot; definition block.</p> <p>2. You should uncheck the accidental torsion in seismic definition, instead use DEC acc parameter in seismic load case to take care of torsion for IS189302016 part 1 code.</p> <p></p> <p>This will solve the issue.</p><div style="clear:both;"></div>
