Abstract Bridge is an adjunct structure as a connection between two edge of road that has been separated under several geographical features. The object research the continuous box girder bridge. Light Rail Transit loading implemented on bridge with 1 and 2 trainsets LRT study case. structure’s geometry, support, material, are modelled finite element analysis software. natural frequencies in ex...

3.1 Overview The proposed equations in the AISC Guide (Murray et al. 1997) for the effective moment of inertia of a steel joist-concrete slab system, Equations (1.7) and (1.8), are based on research from Kitterman (1994) and Band (1996), and a theoretical derivation. The modeling techniques developed in Chapter 2 were used to verify the validity of Equation (1.7) as described in the following s...

Abstract Box girders with steel cantilevers underneath the deck are frequently used in design of composite bridges. Hereby, welded joints between main girder and transverse system have to endure fatigue loads. Current specifications for this joint, e.g., a tapering thickness top flanges at same position transition radius, complex manufacture provide higher resistance than necessary. This articl...

Most of the previous researches conducted on shear lag of box girders were only concerned about simple types of structures, such as simply supported and cantilever beams. The structural systems concerned in these previous researches were considered as determined and unchangeable. In this paper, a finite element method considering shear lag and creep of concrete was presented to analyze the effe...

This article takes a single-tower cable-stayed bridge with steel-UHPC composite deck steel box girder as the research object and develops different casting plans for UHPC layer on deck. It analyzes influence of factors such block sequence deck, whether or not to set up post-casting section, counterweights range it additional deformation stress formed during construction stage, exploring impact ...

Abstract Owning to good mechanical properties, steel–concrete composite (SCC) and prestressed concrete (PC) box girders are the types of elevated structures used most in urban rail transit. However, their vibro-acoustic differences yet be explored depth, while structure-radiated noise is becoming a main concern noise-sensitive environments. In this work, numerical simulation investigate vibrati...

With the increase in traffic volume and overweight vehicles, fatigue problems are highlighted. Especially for orthotropic steel deck, premature cracks seriously affect service performance, operation, quality of bridge. In this paper, box-girder segment model deck substructure considering several typical were established to reveal variation law on vibration frequency deflection under vehicle tra...
