DESIGN OF SEGMENTAL BRIDGES
Q - In spliced girder bridges, is it necessary to provide and account for the fixity of the deck girders to the piers?
A - Where earthquake loads are significant and the resistance of piers to horizontal forces becomes necessary, such as in the case of California bridges, it is common practice to provide for moment transfer between the bridge girders and one or more piers that are designated to take horizontal forces.


ADAPT SOFTWARE SYSTEM TRIAL
Q - I want my colleagues to try out ADAPT programs. What is the best way?
A - If you are a user of ADAPT's Builder, PT, or RC software, simply give your colleagues a copy of your ADAPT program CD. Once loaded, the program works in its "Educational Mode" and allows your colleagues to try it out without having a Key.
Alternatively, interested design engineers can contact ADAPT directly for an educational copy of ADAPT's programs.


ABOUT ADAPT-ABI
Q - How can I get the hyperstatic (secondary) moments that I need to add to my factored dead and live loads in order to arrive at the "design moments"?
A - You do not need to do much. Once you specify the loading condition "Prestressing" in ABI-Gen module, the program automatically calculates the hyperstatic moments and shear and saves it under the name "PH." All you need to do is add the label "PH" to your strength limit load combinations.


ABOUT ADAPT FELT and PULT
Q - I have a tendon with a profile in three dimensions. Which tendon profile do I need to select when I want to enter it in FELT?
A - Use tendon profile type 4. Consider the tendon made up of a number of segments. For each segment you need to enter the length and the angle.
