“…The connected and assembled forms of precast structures including prestressed tendon connection [1][2][3][4], bolt connection [5][6][7], cast-in-place concrete connection(post-pouring) [8], grouted splice connection (grouted sleeves, metal bellows, constraint grout-filled lap connection) [9][10][11] have been extensively investigated and employed in a wide variety of structural application [12]. The prestressed tendon and bolt connections were grouped into dry-connector [13,14], which was convenient construction without post-pouring concrete on-site and exhibited excellent deformability.…”

“…Lv [11] presented a new type of the assembled column-column connection joint that is proposed in the study and studied the force failure process and shape of the assembled column under different stress conditions and the influence of the parameters on the partial pressure bearing capacity and the strain of the steel bar. Liu [12] presented a new type of a precast concrete column-column joint and its corresponding column base joint with a steel jacket for confining the concrete core and the bolted flange plate and verified the reliability of the precast column by experiments. Li [13] completed a test under cyclic loading on 12 laminated reinforced concrete shear walls, the seismic performance was evaluated, and the influence of two different construction measures and construction technology on its performance is also studied.…”

A new type of an assembled monolithic concrete column encased by partial outsourcing steel was proposed, and the seismic performance was proposed. To study the seismic performance such as failure mode, hysteretic behavior, deformation, ductility of the specimen, and the influence of the outsourcing steel pipe on the mechanical performance of the specimens, the comparative tests of four full-scale specimens under low cyclic reciprocating load under a high axial compression ratio were carried out. The test results show that the monolithic column assembled with outsourced steel has better overall performance, and the failure of the specimen is the large eccentric compression failure with good ductility. The hysteresis and skeleton curves of the assembled columns are similar to the cast-in-site concrete column under the same conditions, which have a good ductility and energy dissipation capacity. It was established that increasing the thickness of the outer steel plate does not significantly improve the mechanical performance of the component when the load-bearing capacity of members satisfies the design requirements. The research results can provide a reference for theoretical research and practical engineering applications of assembled monolithic concrete column connections.

This article presented experimental studies on mechanical properties on Plate Type steel Rebar Connector (PTRC), which is composed of steel plate, thread coupler, and steel tube. This is a new method of mechanical connection of steel bars provided in this article for full-precast concrete shear wall structures. The proposed PTRC was tested under monotonic tensile tests, high-stress cyclic tests and high-deformation cyclic tests according to the code (JGJ107-2016). PTRCs were evaluated as Grade I splice through U0, U4, U8, Asgt, and U20 according to the code. The stress distribution curves and end section rotation of PTRCs with different parameters were analyzed using verified Finite Element Model. The calculation methods of PTRC initial stiffness, including stiffness of bolt and threads were provided.
