The numerical model is first validated with actual test results so that they can be adopted for an extensive parametric study with good confidence. The results obtained from the parametric
Note Consult the vignette for some figures comparing the normal, logistic, and bridge distributions. Source bridge are calculated directly from the definitions. rbridge uses inversion. References
Thus, the proposed method could meet the engineering application and be adopted to calculate the lateral distribution factor of bridges with
This study presents an evaluation of shear and moment live-load distribution factors for a new, prestressed concrete, spread box-girder bridge. The shear and moment distribution factors
This paper presents the results of a study investigating the live-load distribution characteristics of box-girder bridges and the limits imposed by the LRFD specifications.
Taking a 3-span box-beam continuous bridge as an example, static analyses of 30 finite element model (FEM) under mid-span load at different span/piece ofthe beam is carried out.
Live Load Distribution in Multi-Cell Box-Girder Bridges and its Comparison with Current AASHTO
The evaluation and design of concrete bridges in large part depend on the transverse distribution characteristics of the live load carried and the
This paper discusses a series of load tests that were performed on an existing adjacent box-beam structure with leaking joints to determine the load distribution for a deteriorated adjacent concrete
We can model the box girder as the real model under the 3D model. It allows us to consider complex behavior in 3D. Especially the box girder shows 3D behavior strongly. In order to do effective design,
Results from testing a simply supported three-cell bridge model is used to substantiate the analytical modeling. Based on the parametric study, moment and shear distribution factors are
This paper reports an extensive parametric study to determine the maximum stress, deflection, and moment distribution factors for two span
Four prefabricated PC box-girder model tests were carried out to calculate the lateral distribution of the live load.
The triple-box girder is finding broader applications in super long-span bridges for its excellent performance of flutter stability and traffic adaptability. In the present study, a bridge girder
Using numerical simulations with a bridge-vehicle coupled model, the study investigates the dynamic responses of five standard box bridges with varying span lengths.
This research study consists of the determination of live load distribution factors (LLDFs) in both interior and exterior girders for horizontally curved concrete box

This paper reports an extensive parametric study to determine the maximum stress, deflection, and moment distribution factors for two span multicell box-girder bridges based on a finite element
Pre-stressed concrete bridges have superior strength and load-bearing capability, making them more cost-effective and efficient than reinforced concrete bridges. PSC box-girder
Use distribution factors and 1-D, line-girder analysis where allowed by the LRFD Specifications. Distribution factors reduce the necessity of modeling the entire bridge using a 2-D or 3-D analysis.
In conclusion, practical methods for engineers to determine the lateral distribution of the live load for the prefabricated PC box-girder bridges with transverse post-tensioning are needed.
Vortex-induced vibrations (VIVs) remain a key issue for slotted box girders. To clarify the influence of additional structural elements on the aerodynamic characteristics of a double-slotted box girder for
Transverse post-tensioning arrangement in prefabricated prestressed concrete (PC) box-girder bridge can effectively improve the transverse connection''s performance to avoid stress
