The subject of the diploma work is a comparison methodology for solving the antifire safety of a production building without a concentrated fire load and with a concentrated fire load. The diploma work deals with this issue on a specific example of a production building. It tries to find out what effect the concentrated fire load has on the results and the subsequent identification of important elements that ensure the stability of the building and avoid the spread of fire in the building. The work consists of five main chapters. The first chapter characterizes the solution of PBS production building. The second chapter sets the goal of the work. The third chapter describes the methodology and next characteristics of the producing structure and its production. The fourth chapter deals with the results of PBS calculations of the production building. In the last fifth chapter there is a discussion in which the results of the work are compared and subsequently proposed more optimal solutions.
