Abstract:
Steel octagon-web beam (SOWB) is a steel structure girder based on the appearance of cellular beam and assembly concept. In order to study the factors affecting deflection, parametric analysis based on finite element (FE) software ABAQUS 2017 was carried out. The factors include the opening type, expansion ratio (H/d) and height-span ratio (H/L). By analyzing the influencing factors on the structural deflection, a reasonable range of factors or the change rule between the two were obtained. In order to calculate the circumferential stress at the web opening, the web unit is divided into five parts according to the characteristics of the web unit and the Vierendeel truss theory. The calculation method of circumferential stress of each part was discussed, which was verified by comparing with the test results.
