Hierarchy Process

A new design method for fire protection, based on analytic hierarchy process (AHP), was put forward, to explore an economic and secure strategy for fire protection of steel staggered-truss structure (SSTS). The chords and web members of SSTS were classified into different important grades by AHP according to the influence which components make on the stability of structure at elevated temperature. And the components are protected by different levels based on the important grades. Furthermore, a comparative investigation was conducted in order to appraise the economic and practical performance of the provided new fire protection method with traditional fire protection. The results indicate that the proposed fire protection strategy for SSTS based on AHP could achieve higher security with the same volume of fire retardant coatings.

Partial Current

Partial current rules of the National Standard of Fire Code are disjointed from the current development of large commercial building; as a result, part of the design cannot be carried out according to the specifications. The new digital fire control design method can solve this difficulty. This paper is to take a large commercial building as an engineering example, introducing the new design concept of “independent fire protection unit” and “quasi-safety area” to adjust the program; then, on the basis of fire safety engineering principles, it uses the computer-assisted method to predict and assess the dangers of fire and the safety of evacuation, and thus demonstrating the feasibility of this method.

In the course of the repair and fire protection upgrading of an approx. 1100 m long road tunnel in Hamburg, the eleven crossings of fire protection channels were covered with sheet steel to prevent the nesting of pigeons. In this context, the mechanical strains that may occur in the event of a fire had to be determined. In particular, it was necessary to clarify which mechanical loads would result from relative movements between the substrate (fire protection board) and the cover sheets due to their different thermal expansion in case of fire. For this purpose, the thermal behavior of the CSH fire protection board was determined by means of simultaneous thermal analysis and dilatometry, and the mechanical and thermal behavior of the composite construction was studied. The studies revealed that due to the facts that thermal expansion of the both materials and due to the softening of the fire protection panel the restraint that is generated by the screwed-on perforated plate in the vicinity of the screw shafts remains low during thermal loading. As a result, the top plate does not crack or break off, which means that screwing on the perforated steel sheets not negatively affects the fire protection of the panels.
