| Abstract: | A new construction of the joints connecting the precast concrete large-scale slabs is proposed.Nine specimens with the new joints proposed by this paper were tested,and the bearing capacity was theoretically analyzed.Behavior of the tested specimens,including load carrying capacity,deflection,strain,crack width,failure process and mode etc.,were measured and analyzed.Failure modes of the slabs include bending failure,shearing failure,and tensing failure.From the test results,it can be concluded that by means of appropriate anchorage length,the new joints between superposed slabs can work very well and have good load carrying capacity and ductility.The bending capacity,shearing load and axial tensing capacity were theoretically analyzed and calculated and the results are verified by the test results. |
| Keywords: | large scale slabs splice joint failure mode ultimate capacity |
