You defined FX FY and FZ releases for certain members. That means these members cannot transfer any axial force or shear force to the supporting members which is not realistic. So the following releases were commented out.
*MEMBER RELEASE
*86 95 98 TO 102 104 176 178 START FX FY FZ
*86 95 98 TO 102 104 176 178 END FX FY FZ
A LOAD LIST command as shown next was added before the CONCRETE DESIGN to ensure that design is carried out for load combinations only.
LOAD LIST 7 TO 9
START CONCRETE DESIGN
CODE ACI
The following commands were added after each UBC load case
PERFORM ANALYSIS
CHANGE
There were a number of redundant analysis commands which were commented out.
You used both PERFORM ANALYSIS and PDELTA in the model. Normally if you are using the ACI code you should be using PDELTA. A PDELTA 15 ANALYSIS was added so that an iterative pdelta analysis is carried out.
For PDELTA ANALYSIS all the LOAD COMBINATIONs have to be replaced by REPEAT LOADs. So LOAD COMBINATION 7 8 9 were replaced by REPEAT LOADs. To understand the difference between REPEAT LOADs and LOAD COMBINATIONs you may refer to the following tech note
For wind load to generate successfully, it has to act on closed panels. For wind acting in Z direction, there are no closed panels at Z =2.5m and between X=14.17m to X=16.27m. So you will either need to define some members or you need to restrict the wind load generation to the face at Z=0. For now, I have done the later by using a ZRANGE command
