Where in the UBC does it specify the number of elevators required for a building? Or is this an owner's preference?

where in the uniform building code does it specify the number of elevators required for a building" from peter birkholz

there is a formulae that depends of dynamic of the passangers who are coming and living the building. Usually have to be analized these processes: 1. filling up the building, when al;l passangers are going from one specific point to different dorections. Cabin in that case is empty. That is so called quasi centrifugal proces, at the bigining of the work. 2. at the end of the working time, there is proces of filling out the building. All the passangers from different directions are going to one exit. That is quasi centripetal process. Car is travelling full but going up empty. 3. During working hours both processes. Car is going up with the passangers and traveling down with passangers too. So there is calculation i.e. formula for traveling time for process of filling up the building with people, also dependes of type of the doors, that will give the time, that will give the capacity and number of necessary elevators, as well as load. Including the index between real and allowed time , the and will be real number of the elevators.
