Hi,
In seismoselect, while defining target spectrum as per IS 1893 (Part 1), what do the terms 'rest category, 'bussiness continuity category' and critical category' imply? In what category does the arch bridge fall? Also, while selecting for design/ inelastic spectrum according to IS 1893(part 1), what extra value should be inputted?

TIA

These are all parameters of the Indian Standard. Their detailed description should be given in the code. It is up to the engineer to decide which are the exact parameters that are to be passed as SeismoSelect input.
