Steel Box Girder Bridges ANDREW LALLY This paper was presented at the AISC National Engineering Conference, Philadelphia, Pa. in May, 7073. THE STEEL BOX GIRDER bridge, because of its structural efficiency and aesthetics, has become increasingly popu lar as a bridge type. Because of four unfortunate erection This study is based on a proposed steel box-girder bridge that would be part of an urban elevated system. The upper structure of the main beam is a 48 m +60 m +48 m steel box girder. The full width of the bridge is 13.5 m, and the steel box girder adopts a single box double chamber section. The bridge layout is shown in Figure 1.Su et al. [19] conducted the experiments on two specimens of steel-concrete composite box-girder with the inclined web. Fangping and Jianting [20] investigated the influence of curvature on the deformation of curved bridges . Bridges often improve the visual appeal of urban landscapes by incorporating curve elements to create iconic forms. However, it is noteworthy that curved bridges have unique mechanical properties under loads compared to .
Prefabricated steel box girders (SBGs) are widely adopted in bridge engineering due to their light weight and low lifecycle cost. To smoothly assemble SBG components on a construction site, it is necessary to inspect their geometric quality and ensure that all the as-is SBG components have the correct dimensions. However, the traditional inspection method is . The steel girder design criteria are obtained from Figures 3-1 through 3-3 (shown below), . Some of the design principles for this design example are presented in "tip boxes." Design computations for a bolted field splice are presented in Design Step 4. Design computations and principles for shear connectors, bearing stiffeners, welded . Here, the steel box girders were modeled using 3D beam elements and meshed based on the positions of diaphragms and supports along the longitudinal direction of the bridge. The entire model comprised a total of 207 elements and 252 nodes. Certain construction details, such as diaphragms, lifting points, and temporary facilities, were simplified .Figure 5.4-2 Precast Box Girder Void Forms, Strand, and Reinforcing Steel (Courtesy of TYLin) For preliminary design, the girder type and associated depth can be taken from Table 5.4-1. This table is based on . . For transversely post-tensioned box girders with longitudinal joints filled with non-shrink grout, AASHTO Article 5.12.2.3.3c .

The purpose of this paper is to model the shear flow capacity of stiffened flange in a steel box girder. The present study uses an energy-based variational approach to analyze the steel box girder. A new parameter is introduced that is strongly correlated to the shear lag response of stiffeners to flanges. A summary of studies conducted to investigate the static and dynamic behavior of curved steel box-girder bridges is presented. Included are descriptions of methods of analysis, experimental studies, computer programs, design aids used in practice, research in progress, and recommendations for future research. The PSC Segmental Box Girder bridge design starts with the Conceptual Design, where the configuration and span arrangement of the bridge are determined. Longitudinal Design is then the verification of the sections at the relevant limit states. Flexural Strength, Shear and Torsional Strength, and Serviceability requirements along the length of the bridge are . It possesses two sidewalks and six vehicular lanes, with a total load defined in the JTG D60 [11]. The design service life of the bridge is 100 years. There are 49 pairs of hangers with a longitudinal interval of 12 m. The main girder is a flat steel-box girder with a full width of 33 m and a height of 3.028 m (Fig. 2).
