Abstract

Fire protection of building structures under the hydrocarbon fire is becoming more relevant, especially in the design and construction of oil and gas and chemical complex facilities, including offshore fixed platforms, liquefied natural gas production and storage facilities and other objects of the fuel and energy complex. The development dynamics of such a fire requires a different approach to testing the structures in order to determine the fire resistance limit. The fire resistance tests of a steel horizontal structure with a fire resistance suspended ceiling of PROMATECT-T plates were carried out under the condition of creating a hydrocarbon temperature combustion regime. A detailed description of the tested ceiling design is given. It is shown that at the time of the end of the fire action, the limit state due to the loss of load capacity (R) and loss of integrity (E) was not recorded when the test reached 120 minutes.

Highlights

Fires have a big impact on buildings and structures as directly when the fire is located on the site itself, and indirectly [1]
The fire effect significantly changes the rigidity of steel beam-to-column connections [4], welded tubular joints are very defenseless without fire protection [5], and the aluminum parts of the structures are most exposed to melting during combustion [6]
Curves of temperature changes in the controlled points on the I-beam steel beams of the prototype of the fire resistant suspended ceiling are shown in Fig. 1 and Fig. 2

Summary

Introduction

Fires have a big impact on buildings and structures as directly when the fire is located on the site itself, and indirectly [1]. The fire effect significantly changes the rigidity of steel beam-to-column connections [4], welded tubular joints are very defenseless without fire protection [5], and the aluminum parts of the structures are most exposed to melting during combustion [6]. In this way, the design of fire protection is a mandatory requirement in the design of structures [7, 8]. General requirements", the method is identical to the international standard ISO 834-75" Fire resistance tests Elements of building constructions". Materials and structures that have proven effective under standard conditions, as a rule, can not provide the required level of protection under conditions of hydrocarbon fire [20]
