Abstract

To study the connection method between reinforced bars of the precast concrete (PC) structure, 81 plug-in filling hole for lap-joint of steel bar sample tests were made, and the main factors, such as reinforced bar diameter, concrete strength and anchorage length etc. were considered during the tests. The test results indicated that the ultimate failure state of all the anchoring specimens were the external reinforced bar yielding or broken up by pulling, and the abnormal anchorage was not destroyed. When the basic anchoring length was reduced by 10% or even 20%, specimens still showed enough safety. Based on this, the basic anchoring length of plug-in filling hole for lap-joint of steel bar can be given as 0.8 l_a.
