D1.I.1.4 Design Parameters
Design parameters are summarized in the table shown later in this section. These parameters may be used to control the design process to suit specific modeling needs. The default parameter values have been selected such that they are frequently used numbers for conventional design.
Parameter Name  Default Value  Description 

CODE   
Must be specified as ASCE to design per ASCE 1097. Design code to follow. See TR.48.1 Parameter Specifications. 
BEAM  1.0 
0 = Perform design at beam ends and section locations specified according to the SECTION command 1 = Perform design at the ends and eleven intermediate sections of the beam 
CMY CMZ

DMAX  45.0 in.  Maximum allowable depth for member selection 
DBL  0.75 in.  Diameter of bolt for calculation of number of bolts required and the net section factor. 
DMIN  0.0 in.  Minimum allowable depth for member selection 
ELA  4

ELB  1 
Indicates what type of end conditions are to be used from among Equations. 3.78 thru 3.710 and 3.712 thru 3.714 to determine the KL/R ratio.
