Fire safety is a major concern with steel structures. Actually, steel structures were not fatally destroyed in most cases of fire. These damaged steel structures may be reused after structural inspection, safety appraisal and necessary repair. Bolted connections are the most widely used connection in steel structures. Slip coefficient is a key parameter to calculate the slip bearing capacity of bolted slip-critical connections. Currently there are few research results available about slip coefficient of bolted slip-critical connections after fire. To obtain the effect of heating and cooling on slip coefficient, a series of slip load tests on connections that had been heated and cooled to ambient temperature were carried out in this study. Methods of friction surface treatment included shot blast and painting inorganic zincs after shot blast. Test results show that heating and cooling have a great effect on slip coefficient of connections with two methods of friction surface treatment, among which effect on connections with shot blasting surfaces is more significant. |
