## 4 Conclusions  
In addition to discussing the state of civil engineering research, this article presents a novel structural design that deviates from conventional FRP-reinforced concrete beams. The following are the study's primary conclusions:  
(1) Through tests on the flexural capacity of six beams with three different grid thicknesses, it is found that all three types of grid-reinforced concrete beams exhibit brittle failure. The flexural tests show different types of failure modes, with the composite material grid concrete beam exhibiting a \"double-line\" failure pattern. There is a significant change in the stiffness of the test beams before and after concrete beam cracking. As the grid thickness increases, the primary mode of failure shifts from pure flexural failure to failure due to the combined action of moment and shear. The cracking load, ultimate flexural capacity, and maximum deflection of the grid concrete beam increase with growing grid thickness, indicating that increased grid thickness significantly enhances the beam's flexural bearing capacity. (2) This study also tested the shear capacity of six beams to get further insights into the mechanical characteristics of the composite material grid concrete beam. Shear span ratio, side grid panel thickness, and a comparison of replacing the bottom grid with steel reinforcement are the primary study factors. The test findings show that the main factor influencing the composite material grid concrete beam's ultimate shear capacity is the thickness of the side grid panel. The shear capacity is also somewhat influenced by the shear span ratio. Two bottom grid panels with HRB400 steel reinforcement and four bottom grid panels made of composite material were employed in the shear test. The results indicate that the steel-reinforced concrete beams maintain their stiffness until they reach their maximum shear capacity, but the concrete beams with grid panels at the bottom see a decrease in stiffness when the concrete cracks. (3) This paper presents theoretical calculations conducted to determine the flexural capacity of the composite material grid concrete beam. A formula for determining the ultimate flexural capacity of composite material grid concrete beams is proposed by combining the structural characteristics of the beams studied in this article with the flexural capacity calculation method recommended by the American Concrete Institute (ACI) for FRP-reinforced concrete beams. The formula may estimate with accuracy the final flexural capacity of composite material grid concrete beams, as demonstrated by a comparison with experimental findings. (4) This paper introduces a novel structure known as the basalt fiber grid concrete composite beam. The design technique of the composite material grid concrete beam is determined by analyzing the results of the bending resistance test, shear resistance test, and the calculated bending load-bearing capacity and shear load-bearing capacity. The design methodology for the composite grating is provided with suggestions for specific measurements of skeletal details. This establishes a specific groundwork for the practical use of this beam type in engineering. (5) The composite grid concrete beam's skeleton component may be designed with greater flexibility and improved structural form due to the inherent material features of the composite material. Hence, a comprehensive investigation through experimental study is necessary to evaluate the shear performance of composite grid concrete beams. Further experimentation is required to examine the synergistic impact of the composite grid frame and high-performance concrete on high-strength concrete beams to fully exploit the mechanical characteristics of high-performance concrete.
