“…Those goals were demonstrated by specified variables, such as, thickness and diameter of the steel tube section. Ibrahim A.M. et al [7] afforded a substantial study presenting the structural benefits that gained by using a composite beams that consisted concrete part and a circular steel tube as an alternative of the IPE steel beam. The behavior of the composite concrete structural steel tube beams with three types of shear connectors (Headed Stud, Angle and perfobond), is the main objective.…”

Steel hollow sections used widely in many engineering applications as structural members. This paper aims to present a study about the flexural behavior of composite beams with steel tubes sections through a series of bending tests in order to study and examine the influence of using different shapes of steel tube section (square, rectangular and hexagonal) with the same shear connector type (headed stud or angle or perfobond) on the flexural behavior and the bending properties of these sections. As well as study the effect of using different shear connectors types (headed stud, angle and perfobond) in the same steel tube section (hexagonal or square or rectangular) on the flexural behavior of composite beams. The experimental program divided into two groups, the first consists of testing nine specimens which focusing on testing three types of steel section when using shear stud at first, angle at second, perfobond at third as shear connector type. Second group consists of testing nine specimens of composite beams too, this group focusing on testing every steel section (hexagonal or square or rectangular) alone when using three types of shear connectors with it. All specimens are with length, width and height equal to 2000, 400 and 130 mm respectively. The tested steel tubes have thickness of 2 mm, yield stress of 322 MPa and the ultimate strength of 390 MPa. The results showed that these shapes of hollow steel sections (hexagonal, square and rectangular) sustain the quality of services for the buildings, and these tested specimens are applicable by giving a distinctive strength and stiffness starting from 114 kN as ultimate load reaching to 170 kN. The experimental results proved that the perfobond and angle connector types are clearly effective shear connectors, shear connector of perfobond type increased the ultimate load of composite beams by (6.25-9.74) % compared with stud shear connector.

This paper presents the behavior of composite slabs with different geometry of profile steel sheet where the strength of composite deck slab mainly depending on the composite action and strength of the connection between concrete and profile steel sheet. In this study, three full-scale specimens of composite slabs with different types of geometry of profile steel sheets (T-shape, triangle shape and trapezoidal shape) were cast and tested under two-point load in order to evaluate the structural behavior and shear bond of composite slabs. The results show that geometry of profile steel sheet have significantly effect on the behavior and strength of composite slab where the ultimate load increased by (32% and 133%) in composite slabs with (triangle shape and T-shape) respectively as compared with trapezoidal shape. As well as the results were satisfy in term of deflection, horizontal end slip, strain and mode of failure.

This paper reviews some experimental and numerical results about the hollow reinforced concrete beams (HRCB). Any subtraction in concrete quantity within the structural members without a considerable lack in load carrying capacity represents a common research trend nowadays due to the decrease in sections dimensions, reinforcing steel and lateral inertia forces in severe earthquakes as well as the sustainability gain for the resulting inhibiting of CO2 emission. In addition, the possibility of passing the electrical and mechanical facilities comprises another good feature of such type of structural members. During the traditional beam design process, the tension concrete is considered as strain transfer agent and do not have any role for structural resistance. As a result, longitudinal holes can be made within this area to produce the hollow reinforced concrete beams (HRCB). In this paper some remarkable research works are summarized with the most important conclusions within this field.
