DASH Input for Example 2
Span interval can be any numbers
from 4-20
4 modes: Steel Composite &
Noncomposite, RC & PC
8 modes for steel
DASH Input for Example 2Position will affect the Effective Width and Distribution Factor
Haunch will affect the section properties and
weight
% of composite will affect the moment
distribution
Detailed factor applied to steel section only

Spacing is required for Distribution Factor and
DL calculation

DASH Input for Example 2
2 unique PG sections are defined
DASH Input for Example 2Members are
defined from left to right in an
ascending order
These 3 entries are for non-
prismatic members
These 3 entries are for hybrid
members
DASH Input for Example 2
HS loading can be from 1 to 99
If =2 proportional to the HS loading
For fatigue use
DASH Input for Example 2If not a staging case, slab
loads have to be defined span by span or total span length.
For a staging case, slab distances can be arbitrary.
Pouring no. & Day are used for
staging
DASH Input for Example 2
For the proper calculation of moment capacity, distance has to be equally divided by the lateral bracing spacing
Not for hybrid sections
