The paper points out some limitations of current design methods such as that proposed by Eurocode 4 for the prediction of the deflection at serviceability limit state of propped and unpropped steel-concrete composite beams with partial or complete connection. By using a purposely developed non-linear...
Deformations of an I-section steel beam under equal end moments are studied in this article. Initial geometric imperfection of the beam axis was introduced according to the Eurocode standard. Numerical studies have shown that the lateral deflection of slender beams under major axis bending can be ...

According to Eurocode [18], hot-rolled steel members are mostly in class 1 or 2 cross-sections while CFS belongs to class 3 or 4. Most of the research carried out in past on CFS was at ambient temperature, which helped in the preparation of design code EN 1993-1-3:2005 [19] at ...

When the bending moment M was equal to 0.2Mue, the specimen reached the limit of the elastic stage. With the loading increased, the specimen had plastic deflection and entered the elastic–plastic stage. When the bending moment M was equal to 0.7 ~ 0.8Mue, the steel tube in tensile...
Appropriate limits for deflection can be found from the governing building code. For the common case of a simply supported, uniformly loaded beam such as that in the following Figure, the maximum vertical deflection is: Deflection limit:

Therefore, the fundamentals of rotations in a beam and the derived methods to estimate the bridge deflection using rotations are not applicable to this structure. In addition, the external prestress system has a significant influence on the response of the structure to temperature changes. Further...
