Abstract -In this study, reinforced concrete has been
inexpensive from an engineering standpoint than traditional reinforcing systems. Compared to traditional reinforcement systems, PCS can be thought of as being more cost-effective. The fabrication of PCS reinforcement uses far less material than traditional reinforcing systems and takes much less time. Additionally, fabricating PCS might considerably cut labour costs. Reducing labour costs, which account for a significant portion of construction costs, lowers overall construction costs. the use of PCS reinforcement in columns provides a considerable saving from construction costs and time.

The results of the tests clearly show that the adoption of rectangular spiral reinforcement improved the shear performance and bearing capacity of the tested beam.

1. INTRODUCTION
In this study, prefabricated reinforced beams with various thicknesses are compared to conventional RCC beams and columns in terms of their ultimate capacities, flexural performances, spiral confinement effect, ductility behaviour, load v/s displacement curves, and opening shapes of the stirrups with various breadth. The models are done by using ANSYS 2022 Software, and results are compared to conventional RCC beam, the diamond shape performs significantly better than the conventional RCC.
One of the most popular composite systems worldwide is reinforced concrete. The effectiveness of individual reinforced concrete system components has an impact on the effectiveness of the system as a whole. To enhance the performance of structural elements, research has been done on a variety of technologies that could replace the traditional reinforced concrete system. The Prefabricated Cage System (PCS) is one of these studies. his approach is based on the idea of using perforated steel pipes or plates in place of the traditional concrete reinforcing. Work on PCS-reinforced columns using standard and high strength concrete the studies revealed that the columns reinforced with PCS exhibited elastic behaviour similar to that of conventionally reinforced concrete systems, but they also displayed more ductile behaviour, had a higher energy absorption capacity, and increased the strength and displacement capacity of the column. Furthermore, it was discovered that the PCS's confinement effect kept the steel from buckling.
1.1 PCS system and confinement effect One of the most common composite systems utilized globally is reinforced concrete systems. The effectiveness of the reinforced concrete system as a whole is influenced by the effectiveness of its individual components. To enhance the performance of structural elements, research has been done on a variety of technologies that could replace the traditional reinforced concrete system.in this the load capacities of reinforced beam and column, to enhance the structural performance of beam and column prior to the conventional system. For this the thickness is varied from 3
Although the production of PCS reinforcement can be more expensive than conventional reinforcement for a particular structural member, PCS can be thought of as more
