“…Meanwhile, after all of the primary cracks occurred, the carbon-reinforced beam's strength continues to increase until it reaches the failure point, which is regulated by the final strain of the textile reinforcement. The TRC beam, on the other hand, has a lower deflection at service loads than the SRC beam [38]. Although both beams have the same slope at service loads, the TRC beam deflects roughly 50% less than the SRC beam.…”

The effectiveness of textile-reinforced concrete (TRC) and steel-reinforced concrete (SRC) in the flexural performance of rectangular concrete beams was investigated in this study. To better understand TRC behaviour, large-scale concrete beams of 120 × 200 × 2600 mm were tested and analysed in this work. Cover thickness, anchoring, and various layouts were all taken into consideration to assess the performance of beams. In addition, bi-axial and uni-axial TRC beams and SRC beams were classified according to the sort and arrangement of reinforcements. The findings showed that anchoring the textiles at both ends enhanced load resistance and prevented sliding. The ultimate load of the tow type of textile reinforcement was higher, attributed to the increased bond. Variations in cover thickness also change the ultimate load and deflection, according to the findings. Consequently, in this investigation, the ideal cover thickness was determined to be 30 mm. Furthermore, for the similar area of reinforcements, the ultimate load of TRC beams was noted up to 56% higher than that of the SRC control beam, while the deflection was roughly 37% lower.

The application of Cold-formed steel (CFS) is getting popular in several countries, and this indicates that a good potential of using lightweight materials as an alternative solution to conventional steel. However, there is still a lack of information about joint behavior, particularly composite connections integrated with CFS. This paper presents an isolated joint test of composite joints consisting of concrete slab 100 mm thickness, double lipped channel section used for beam and column, connected by hot-rolled steel gusset plates and bolts. The weakness of the thin plate behavior in the compression zone was reduced by installing the angle stiffener on the web column. Two specimens with the same configuration but with and without seat angle were tested. The experiment results revealed that by the use of seat angle, the moment resistance and stiffness of joints increased with the ratio 1.06 and 1.19, respectively.

Cold-formed steel (CFS) members designed with proper stiffener can significantly increase the loading capacity of the connected member even though they are thin and slender. Design recommendations of connections especially for CFS sections are mostly related to the load-carrying capacities of individual fasteners such as bolts, screws, and rivets. The proposed bolted top-seat flange cleat joint in this paper should be able to categorize as semi-rigid that can further enhance the use of CFS in structural steel. This paper aims to investigate the behaviour of cold-formed steel section with gusset plate integrated with angle cleats. The full-scale isolated joint test was conducted on three specimens where the size of column size is C30024, and the size of beams is C20024, C25024, and C30024. All sections are 2.4mm thick. The connections were stiffened with a rectangular gusset plate of 10mm thick and angle cleat of 6 mm thick, respectively. The result of the test showed that the moment resistance (Mj) of the connection for beam sections C20024, C25024 and C30024 were 45.3 kNm, 48,8 kNm, and 52.5 kNm respectively. The initial stiffness (Sj,ini) of the connections for beam section C20024, C25024 and C30024 were 510 kNm/rad, 650 kNm/rad and 610 kNm/rad respectively. The experimental results showed that the ratio of the moment resistance ranged from 1.00 to 1.16, and the ratio of initial stiffness ranged 1.00 to 1.35 as compared to the numerical analysis adopted from EC3 code.
