“…As the impact test result indicates, using in-filled tubes in place of traditional bars will be safe and permitted [2]. A 28-day curing period is required for test specimens measuring 230 mm by 300 mm by 1500 mm to be used in the flexural test on beams.…”

In today developing consequence, innovative alternates are being familiarized from recycled wastages used in concrete construction. This study concentrates on alternate reinforcement in the structural elements. The conventional reinforcement is replaced by the rubber composite reinforcement using in-filled tubes. The bond relation among the mild steel tube and concrete is simply good. The performance of the composite reinforcement using rubber in-filled tubes are comparing to the conventional reinforcement. The composite reinforcement is made by in-filling the mild steel tubes with cement slurry and crumb rubber. And the crumb rubber gained from the cracker mill. This crumb rubber institutes to the solid waste management. The scrap tires are prepared into crumb rubber and mixed with water – cement in a mortar ratio of 1:1:2 (water: cement: sand) to attain the colloidal consistency. 40% of 177-micron size crumb rubber sieves replaced instead of sand. This crumb rubber constitutes to the solid waste management and light weight. Hence these composite reinforcements will reduce weight of steel in reinforced concrete along with the decrease in cost of construction. This idea inspects the flexural strength of concrete beam with composite reinforcement, Mild steel pipe reinforcement and ordinary reinforcement by third point loading.

“…The local buckling failure of the brace member was the main failure mode during the tests. Dessouki et al [7] performed a monotonic loading test on five connections of steel I-beams to square CFST columns, and the effect of column stiffening dimensions and filling the column with concrete on the ultimate bending moment of joints was analyzed. Deylami et al [8] completed the low-cycle reciprocating loading test of the connection between I-beam and a built-up box column, investigated the effect of the geometry and position of the vertical rib plate on seismic behavior, and performed finite element analyses to confirm that the reinforcement of the vertical rib plate can significantly enhance the performance of the joint.…”

A considerable amount of welding has a negative effect on traditional joints. Experimental and numerical studies of new bolted outer shell joints under low reversed cyclic loading were presented, and a total of four outer shell joints of Hshaped steel beam and square tubular column were tested with experimental parameters, such as sectional dimensions and concrete in the tubular column, to improve the beam-to-column joint form. Moreover, the cooperative deformation behavior between the outer shell and the column wall was discussed. In addition, complementary finite element simulation was used, and its results were compared with the experimental results. On this basis, the main indexes that affected the performance of the joints were analyzed. Results show that the hysteresis curves of the outer shell joints are full, the bearing capacity and initial stiffness are significantly improved with the increase in the sectional dimensions, while the ultimate rotation angles are reduced, degrading the stiffness to 0.13-0.24 times its initial stiffness at the last loading level. Notably, the strain ratios of the outer shell and the adjacent steel tubular column are approximately 1:2.5 in the elastic stage. Parametric analysis shows that the thickness of the outer shell should be approximately 8 mm. Similarly, the 11 mm thick T-steel web with regard to the setting stiffener is significant in improving bearing capacity. The proposed study provides a theoretical reference for the application of outer shell joints in practical engineering.

“…Li et al (2011) analyzed the effect of parameters such as the beam-column stiffness ratio, axial compression ratio, and annular plate characteristics on the seismic resistance for such types of joints. Dessouki et al (2019) analyzed the effect of the annular plate shape, with or without concrete, and concrete strength on the joint bearing capacity. The findings indicated that the impact on the bearing capacity of the specimens is determined by the filled concrete to a greater extent than by the shape of the outer annular plate.…”

In recent decades, connections between concrete-filled steel tubular columns (CFST) and H-steel beams have been well designed and implemented. However, owing to poor construction quality, brittle failure often occurs at weld seams. In this study, an innovative joint was developed to connect CFST columns and H-steel beams using a top-weld bottom-bolt (TWBB) connection to minimize the effect of welding quality on the seismic resistance of joints. Six specimens were designed for cycle-reversed loading tests to discuss the seismic performance of this joint. Four configurations, including different connection methods, beam heights, column forms, and stiffener thicknesses, were considered in the test. The impacts of different configuration forms on the failure mode, strength, stiffness, ductility, and energy dissipation of the specimens were evaluated.The test results demonstrated that the columns with or without concrete had a significant effect on
