how can i eliminate this warning **WARNING: TENSION/COMPRESSION REQUESTED IN SAME RUN THAT INCLUDES A DYNAMIC ANALYSIS. and even after considering the Z direction in Response spectrum analysis i am not getting Z direction values

The model contains MEMBER TENSION specification and Load Case 3 is a response spectrum load case. In the Help manual it is mentioned under section TR.23.3 Member Tension/Compression Specification that if response spectrum load case is present MEMBER TENSION command should not be used. Hence program is throwing warning message. To remove this warning introduce Perform Analysis-Change command followed by MEMBER TENSION 0 before Load Case 3. MEMBER TENSION 0 switches off all tension only specifications for load cases which are specified subsequent to this command. Regarding zero values along Z direction notice that program by default extracts first 6 modes and Z direction mass participation is zero in the first 6 modes. To ensure mass participation along Z direction increase the modes by using CUT OFF MODE SHAPE 100 command.PEB.RESPONSE SPECTRUM ANALYSIS_mod.STD
