ON DESIGN OF EVACUATION EXITS IN CORRIDOR BUILDINGS OF PIECEWISE RECTANGULAR TYPE

Abstract

When designing corridor-type buildings there is a question about the optimal placement of evacuation exits along one or both sides of a long corridor. The previous paper [1] considered the issue of uniform distribution of exits for both wide and narrow corridors, and there was presented the corresponding criterion. The present paper is a continuation of the work [1]. It considers the optimal arrangement of EEs on both sides of a piecewise rectangular corridor in residential and office buildings (letters P) if such device is not provided in the project. In this case, the requirement of maximum distance of EEs from each other minimizes the mixing of human flows during a fire. The nonclassical Maximin problem (maxmin) is formulated, for the solution of which there is proposed a numerical method of direct search – MLV. Calculations were carried out according to the developed program in the TurboPascal-7 language.
