v4.0.0 -
ACI 318-19
The user can now specify if design should follow ACI 318-14 or ACI 318-19 on the Design Criteria tab under Specification.
This option changes many calculations. To summarize the changes in more detail, see the page ACI 318-19 Changes.
New analysis option for confinement factors for mild development length of bars with hooked or headed ends.
This option behaves slightly differently depending on if ACI 318-14 or ACI 318-19 are being used. More information can be found in the documentation for the option.
New load pattern selector
New options can be found throughout the Analysis Report which can be used to specify which load combination / load pattern should be used for the corresponding output.
These options allow the user to use the worst case or specify the following:
Load Combination
Live Load Case
Wind Load Case
Seismic Case
Location on Column (when applicable)
The options can be found on at the following sections throughout the output:
Strength Results
Service Results
Detailed Flexure
Cracking Behavior
The user can now specify if the design should be checked as a cracked section.
