摘要：Friction-type high-strength bolt connectors are widely used in steel structure. However there has only general description for connection plate surface treatment method in the current Chinese design standards. Some research tests have been designed for different connection plate surface treatment method, which include different painting thickness and different blasting method. The results show that different treatment method has different anti-sliding coefficient. The anti-sliding coefficient would decrease with the surface coating thickness increase. The anti-sliding coefficient would less than 0.50 which the Chinese design standard required when some surface treatment methods are used, such as using steel wire section or using mixture of steel wire section and steel shot to sand blasting. So procedure qualification test is necessary to guide processing in order to ensure the quality of the products. It has certain conference value for practical engineering.
