What lateral loading do I apply to a playground structure in an existing building (Space Frame)? 2

[Mike C]

The plan checker is requesting a 3D analysis of a playground structure that weighs 4k and is located on the second story of a two-story concrete slab-column building in the Bay Area (California). The frame elements are galvanized pipe sections with base plates anchored into the elevated slab. I need to know what seismic loading to apply in the model for this grid structure. Since it essentially has no diaphragms, I assume I should load it with the mass of each element. However, I have no experience with this type of lateral loading, so I would appreciate any quick and direct answers to help me analyze this structure and move forward. Thank you.

There are lots of weird specialst specs (I've touched climbing walls and bunk beds, both of which have suprisingly specific engineering requirements), so I took a look to see what's out there.

If you're specifically looking at playground structure loads, there's astm F1487. It has required test loads for playground equipment that also allow certification by an engineer for the same loading conditions as an alternative. They look pretty annoying to apply though and it's clearly meant to allow for ease of testing and not necessarily for examining all the cases. Swing strength, for instance, is a downward test force and no lateral force.
