handicap ramps
quick question:
this is not a structural question, and architect handed me plans to design a ramp that is not straight. it is almost semi-circular! (those architects). this got me to think about this from practical standpoint. her is my question:
can handicap ramps be curvilinear (or on radius)? i think this is not practical and the florida accessibility code is not clear. in all of the years of my experience, i never done one like that.  i always saw them straight.
any input would be greatly appreciated.
thanks
great query lufti.  i have no idea regarding statutory requirements for wheelchair ramps, however in my city i've seen plenty of "helical" pedestrian ramps as access-ways to road and rail crossings.  the ramps have flat spots in them every so often too.  these are recently built public structures so assume they were designed with due consideration for wheelchairs.
dbuzz,
florida has the "florida accessibility code" which is tougher than the ada. if you meet fac, then you meet ada by default. i just think that a radial ramp is awkward for a person in a wheel chair especially when the ramp is within the path of egress.
i appreciate any input.
