## 6 Conclusions  
This study explores the limitations of conventional integrated joint assemblies and introduces a fresh, assembled concrete beam-column L-shaped reinforced joint model. The research encompasses the conceptualization and production of one cast-in-place joint and four assembled joint exemplars, as well as low-cycle cyclic loading tests to investigate the mechanical mechanisms, failure modes, and seismic performance of these joints. A nonlinear analysis of the joints is executed using ABAQUS, with simulation and test results compared to each other. The model's accuracy is verified, and a parametric analysis is conducted, resulting in a formula for calculating shear capacity. Key conclusions include:  
1. The size reinforcement of the beam column itself is designed according to the specification, and the column steel bar is continuous when connected, and the beam steel bar is bent to the column. Therefore, the design and production of the beam column itself has met the requirements of the strong column and the weak beam. Cast-in-place joint XJ-1 and newly assembled joints ZP-1, ZP-3, and ZP-4 exhibit bending failures at beam ends, complying with the seismic design requirements of \"strong joints and weak members.\" Joint ZP-2 uses short L-shaped reinforcement, effectively reducing the vertical force component while increasing the concrete load, leading to shear failure in the joint area. 2. The newly assembled joints demonstrate excellent energy dissipation, damage resistance, and ductility. The stiffness degradation coefficient is above 0.75, indicating impressive damage resistance within the cast-in-place joints. 3. The force at the joint is more complex, and there are many factors affecting the seismic performance of the joint. In this paper, the influence of the main factors on the seismic performance of joint specimens has been studied. The study reveals that implementing measures such as increasing the area of post-cast concrete in the joint, extending the length of L-shaped reinforcement, and enhancing the concrete strength in the composite beam area can effectively improve the bonding force between the post-cast and precast members, subsequently boosting the joint's ductility, energy dissipation, and load-bearing capacity. Pre-placing steel tubes in columns can significantly enhance the initial stiffness of joints. It provides an effective basis for the research of the \begin{table}

A comparative analysis confirms the strong alignment of the theoretical calculations with experimentally and numerically derived shear capacity values. The results show that the proposed formula meets the needs of design and application, and provides a reliable reference for the calculation and analysis of the shear capacity of the newly assembled joints. Beam-column joints represent a pivotal research focus for the seismic analysis of assembled structures. The paper proposes a novel assembled concrete beam-column L-shaped reinforced joint and preliminarily investigates its seismic performance via pseudo-static testing and finite element simulation, but there are still shortcomings. For the successful development and application of this new joint model, the following considerations should be prioritized:
