| 摘要： | The writers would like to thank the discussers, Osborn and Chicchi, for their special interest in the original paper. Their comments and wealth of suggested references are greatly appreciated. The study presented in the original paper was motivated to establish cost-effective and easily implementable positive moment connections between precast concrete bridge girders and bent caps, making the use of precast concrete girders in seismic regions cost competitive to cast-in-place construction. In this effort, unstressed strands extending from the ends of precast concrete girders are used as the connecting reinforcement. The writers agree with the discussers that the bond of strands is influenced by many factors, which has been shown in many studies, including those that the discussers cited. The writers did not perform bond tests in accordance with ASTM A1081 because the width of the bent cap mainly determined the anchorage length in our tests. Furthermore, the intent of the tests with straight ends was to determine the maximum force that the strand can develop and measure the corresponding slip as a function of the force. With this information, we were able to determine whether the provided strand embedment length was adequate for the particular connection demand and the required capacity of a supplementary mechanical connection if needed to ensure full development of the unstressed strand. |
