Present bonding methods which connect steel pipe and spread footing in pile foundation have been generally used. These methods however showed lots of difficulties in the quality control. A new bonding method, which is called 'Bolted Bonding Method(BBM)' , is developed. This method uses factory-made parts so that it may increase the degree of quality, and workability, and is being adopted in the Held concerned. The method is verified by the structural analysis and laboratory test and then a new design formula is proposed. In addition, a comparison test of the present methods and BBM are conducted to observe the applicability and economy of the latter. As results, it is observed that BBM shows 5 to 10 times faster in Held work and 9% to 50% cheaper in construction cost than the existing methods.

Recent experimental research results of connection method between steel pipe pile and concrete footing are provided based on various experimental observations. It gives a shedding light toward developing better and concrete connection method for steel pipe pile at the field application. In this study, the newly developed method is tested for compressive, pull put and combination load including moment with carefully designed monitoring system. The measured data show that new method have at least equivalent or better load resistant capacities compared with those of specified method in Korea Highway Corporation design code. It is also tried to define and investigate the load transfer mechanism for new method.
