摘　　要：将改性后的硫氧镁(MOS)无机胶连接与无机胶复合竹组成复合连接结构,讨论了6种连接形式、2种胶体类型、2种胶层厚度对无机胶复合竹钢填板连接承载能力的影响。结果表明:有机胶混合连接最有效,改性MOS无机胶纯胶体连接效果最差。相同连接形式下,胶层厚度增加,峰值荷载略有降低,延性略有提高。Eurocode 5预测螺栓连接承载能力时适用性较好,但预测胶体连接承载能力时最大偏差为14.9%。The modified MOS inorganic glue connection with inorganic glue composite bamboo was composed of composite connection structure,and the effects of six connection forms,two colloid types,and two glue layer thicknesses on the load carrying capacity of the inorganic glue composite bamboo steel filler plate connection were discussed.The results show that the organic glue mixed connection is the most effective,and the modified MOS inorganic glue pure colloid connection is the worst.Increasing the thickness of the adhesive layer resulted in a slight decrease in peak load and a slight increase in ductility for the same connection form.The design equations in Eurocode 5 provide a better prediction of the load carrying capacity of bolted versus colloidal forms of connection,but the prediction of the latter is not as accurate,with a deviation of up to 14.9%.
