| Research Abstract |
The buildings which wheelchair users can use are increasing after establishment of the "heart-buil"act.But till now, basic data remain very poor to make effective escape plans required in case of fire for a crowd including wheelchair users.In this research, to simulate actual escape of such crowd, we set up several sorts of conditions such as types of waiting space, outflow width of openings, crowd density, and mixing rate of wheelchair users, md then carried out an experiment in a university gymnasium by students, to obtain the basic data of the crowd outflow characteristics.The results are as follows ; (1)The decreasing rate of the outflow coefficient with the mixing rate of wheelchair users is experimentally quantified.Since an experimental crowd, of course, differs from the real crowd at the time of panic, the value itself of the outflow coefficient must be considered to be different, but this decreasing trend can be considered to be almost equivalent.(2)This trend may contain a certain deviation, but it can be quantified as a function of the mixing rate.(3)According to this functional relationship, and using the value of 1.5 persons/m・sec as an outflow coefficient at the case of 0% of wheelchair mixing rate, the outflow coefficient at any case of mixing rate can be calculated and applied to practical use.
