This paper proposed a new lateral joint to connect precast concrete hollow‐core slabs (PCHSs) and increase their structural assembly efficiency. The main sensitive parameters are the longitudinal ribs and the number of proposed joints. Out‐of‐plane bending performance tests were conducted on four PCHSs with lateral joints (PCHS‐LJs) to study the effects of the main sensitive parameters on the mechanical properties and failure modes of the PCHS‐LJs. The test results showed that there is no obvious relative slip in the joints between the precast bottom slab and the upper post‐pouring concrete before PCHS‐LJs reaching the ultimate load. The transverse directions of PCHS‐LJs are the main force bearing directions and the cracks are mainly occurred in the longitudinal direction of the specimens, which is similar to the stress characteristics of one‐way slabs. Moreover, the vertical bearing capacities of PCHS‐LJs are increased when decreasing the number of proposed joints or when adding the longitudinal ribs. For the specimens without the longitudinal ribs, a wide transverse crack appears near the first transverse ribs, whereas the specimens with the longitudinal ribs do not exhibit this phenomenon. Thus, longitudinal ribs should be added to optimize the PCHS‐LJ failure modes. Finally, solid finite element (FE) models of the test specimens were established in MSC. MARC. The analysis results are basically consistent with the experimental results.

Semi-precast reinforced concrete (RC) slab, consisting of a precast plank with steel trusses, and a cast in-situ concrete topping, has attracted more and more attention owing to its low formwork cost and low labor work. In order to investigate the influence of joint on the slab flexural performance and the force transfer mechanism at the joint, eight semi-precast RC one-way slabs were fabricated and tested under four-point bending condition. The investigating parameters included the fundamental design part (i.e., whether designed with joint or steel truss) and geometrical parameter (i.e., slab thickness, steel truss spacing, and lap-rebar length). The load-deflection relationships, crack patterns, failure modes, and strain distributions were studied. Meanwhile, twodimensional finite element (FE) analysis based on FE software MSC.MARC was conducted to reproduce the test. The results indicated that (1) the steel truss could help to avoid the brittle failure in the semi-precast RC one-way slab with joint, and lead to a ductile failure; (2) the steel truss spacing and the laprebar length would influence the load carrying capacity of the semi-precast RC one-way slab; and (3) the FE model could well predict the flexural performance of the specimens and could be used for further investigation.
