Minor changes in the
physical model (from OBM) will result in the reset of the various parts in
superstructure and substructure of the analytical model.
Any change other than
major change is considered as minor change. For superstructure, typical minor
changes include change of span length, beam spacing, beam sizes, etc. For
substructure, typical minor changes include change of dimensions of bent cap,
column and footing, locations of bent column and footing, et al.
The results of minor
changes
If the input is
entered as absolute value (in terms of ft, et al.)
The absolute
will be retained if the load or reinforcement fits in the limits of the beam
The absolute
value falling outside of the beam limit will be deleted
If the input is
entered as relative value (such as 0.50L)
Relative value
will be retained (its absolute value may change if the span length changes,
accordingly)
