h2. How are line loads applied to membranes?

*Answer:* To apply line loads to deck-type objects, several options are available, including:

* Add these loads as distributed loads to decks, usually as small partition loads for decks without beams underneath.

* Add loads directly to supporting beams.

* Use [shell|kb:Shell]-type objects.

h2. For time-history analysis, can different ground motions be applied to individual supports?

Yes, please see the [Displacement time-history record|kb:Displacement time-history record] article for details.


h2. Is it possible to apply multiple live-load patterns separately?

*Extended Question:* I am interested in applying various live-load patterns to determine the governing configuration. When I specify LIVE_LOC1 and LIVE_LOC2 as separate patterns, both of LIVE design type, the combination 1.2*DL+1.6*LIVE_LOC1+1.6*LIVE_LOC2 is automatically generated. How do I apply these patterns separately?

*Answer:* [Load-pattern|kb:Load pattern] design types correlate with specific design post-processing methods such that design [load combinations|kb:Load combination] are automatically created with the appropriate load factors.

For the configuration described, the separate live-load patterns may be applied by manually creating load combinations as follows:

* 1.2*DL + 1.6*LIVE_LOC1

* 1.2*DL + 1.6*LIVE_LOC2
