LEAP BRIDGE STEEL

I have the following two questions. (Please note that I found related answers, but they are from several years ago):

Q1. Does the current version of Leap Bridge Steel perform Load Factor Design (LFD) and Load Factor Rating (LFR)?

I am seeing where one can select the AASHTO LRFD Specification, but not the AASHTO Standard Specification.


Q2. How to model an integral pier cap?

Is there any suggestions in how to model the support, in terms of considerations for elastic-spring constant for translation and rotation, to somehow simulate the condition of the girders at the integral pier cap?

Thank you for the help.
