Description
Summary:In order to study the seismic performance of underground utility tunnel prefabricated joints anchored by button-head reinforcement, pseudo-static tests were carried out on two full-scale underground utility tunnel prefabricated joint specimens. The failure mode, bearing capacity, energy dissipation, and other seismic performance of the joints were analyzed. The results show that the bearing capacity, energy dissipation and other seismic performance parameter of these specimens can meet the seismic design requirements. However, the damage in the core area of the joint is severe under the pseudo-static loading. Therefore, when the button-head reinforcement is applied to practical engineering, necessary reinforcement measures should be taken to ensure that the joint has good seismic performance.
