“…However, the real dynamic action of vehicles moving across short-span bridges is not reliably described by Eqs. (24) and (25). The effect of the moving mass is fairly Bridges Subjected to Dynamic Loading http://dx.doi.org/10.5772/intechopen.73193 small compared to that of other factors which produce high dynamic stresses in such bridges.…”

“…In addition to specifications of most codes, the dynamic effects of vehicles on bridges are considered by multiplying the static live loads by a dynamic load factor (DLF = δ) greater than one; DAF-there are many ways of interpreting this simple definition of the DAF from test data, see also, e.g., [19,24].…”

“…The dynamic loading test and the following dynamic monitoring of the Lafranconi bridge over the Danube in Bratislava (Slovakia) are shortly described in this section [38][39][40]. The dynamic response behavior of a prestressed concrete, seven span highway bridge (761.0 m long) was examined via DLT according to standard [24] in 1990. Excitations of bridge structure were induced by the passage of two fully loaded, multi-axles lorries as well as by the rocket engines.…”

This chapter reviews the analysis of problems of highway and rail bridge dynamic response to moving traffic loads. Bridge vibrations analyses comprise solution of many interdisciplinary problems. During the two last centuries, these problems have been studied by theoretical, numerical and experimental way by many investigators. Therefore, the present chapter contains only the basic approaches for solving the complex problem of bridges subjected to dynamic loading.

“…Alternatively, the DAF can be specified in terms of a dynamic load allowance (IM) (Deng et al 2015, Beben 2013 Where L is span length. According to articles 3.8.1 and 3.8.1.2, I is zero for culverts and structures having more than three feet of fill (AASHTO 2002).…”

In the current practice of bridge engineering, structures are designed and evaluated using static loads. In order to account for the dynamic nature of the true loading condition, static vehicle loads are increased by a dynamic amplification factor (DAF). The DAF has been widely studied for conventional bridges and has been found to be a function of vehicle forcing frequency and the fundamental frequency of the bridge. As a simplification, many design codes determine the DAF factor based on common bridge characteristics, namely the span length. The AASHTO LRFD Bridge Design Specifications simply use a single, conservative value for conventional bridge types. In the case of buried bridge structures, the dynamic behavior is complicated by the soil layer present between the asphalt and structure. In order to accurately determine the response of buried box culverts in a dynamic loading scenario, the interaction between the asphalt, soil, and structure must be taken into account. Through a parametric finite element analysis, four aspects of the asphalt-soil-structure system are examined in order to determine the factors which most influence its dynamic response. Parameters under scrutiny are depth of fill, fill stiffness, culvert span length, and culvert flexural rigidity. This research shows that fill depth and slab thickness are most influential in determining the dynamic amplification factor. However, span length and soil stiffness do have some effect.
