The centrifugal force (Horizontal Moving Load) has two components, the radial force and the overturning force. The radial component of the centrifugal force is assumed to be transmitted from the deck through the end cross frames or diaphragms and to the bearings and to the substructure. The overturning component of centrifugal force occurs because the radial force is applied at a distance above the top of the deck. The overturning component causes the exterior wheel line to apply more than half the weight of the truck and the interior wheel line to apply less than half the weight of the truck by the same amount. Thus, the outside of the bridge is more heavily loaded with live load. The overturning force is computed by taking the sum of the moments about the inside wheel and setting the sum equal to zero. The result is that the outermost girder will receive slightly higher load and the innermost girder will receive slightly lower load. Thus, it is also necessary to compute the condition with no centrifugal force, i.e., a stationary vehicle, and select the worst case.

Currently, Prestressed Concrete Beam Bridge, which is generally applied as the most economical bridge type for small and medium-sized bridges in construction works such as highways and national highways, has been introduced to the entire bridge construction field for almost 60 years after the technical proposal.
In this post, we will look at the initial development story and trends of the Prestressed Concrete girder.

When a static concentrated load is applied on a deck, the deck will deflect transversely as well as longitudinally, similar to the structural behavior of a two-way slab. The load distribution becomes more complex when multiple point loads are applied to the deck, such as truck loads. When the structural model is simplified to a 2D frame model, it is important to obtain the resulting 3D forces from the 2D model.

Loading on structures can be idealized as static loads and are one of the major issues for structures. It makes permanent deformations to structures during the service period. The dead loads can be applied in the structural analysis as static loads. The static loads include nodal loads, distributed loads, and pressure loads in the structural analysis software. midas Civil also provides various load types to cover various loading conditions. In this webinar, we will examine how static load types are applied and which static load types are available.

Material properties must be applied when performing analysis. midas Civil provides 'Material Properties' function to define various materials. Some users who are a beginner or are not familiar with midas Civil might be confused while defining a material property because there are various options. These options are used for linear analysis or nonlinear analysis and those are used or not depending on the purpose of analysis.
