MIDAS Alignment Generator Plug-in for Road and Railway Projects

midasBridge TeamJanuary 9, 2024

   In railway or highway design projects, structure engineers always receive decided alignment from the project manager. Highway or Railway alignment usually changes slightly because of many external factors while working on a project. Sometimes, slightly changed alignment can have potential critical issues to construction or other project steps, serviceability, and even a legal issue. For example, a transition curve is related to drivability and driving safety. If so, structural engineers must recognize and consider that minor change. Let's look into how structure engineers change alignment during their projects.

It's time for a review, as usual. Do you remember Offset function in CIVIL NX?

Let me reiterate. You cannot apply a Beam End Offset at the same time when a Section Offset is in place. It is not possible to apply Offsets simultaneously.

For more details, you can click on 'Offset function in CIVIL NX' to check it out!

CIVIL NX AtoZ : Offset function in CIVIL NX

Hello everyone, Welcome back 🎉. This is CoBen!! 👬

Do you remember the content we shared last week?

For those who may have missed the previous content or are a bit unclear, let me briefly summarize it. 🤓

Last week, we shared a method for simultaneously checking multiple loads.

Click on the Display menu in the View tab, and in the Load tab, check on specific loads or load combinations you want to represent. This will display all selected loads on the model.

For more details, you can click on 'Displaying Multiple Loads Simultaneously' to check it out!

How to Define Section Properties in Various Bridge Design Conditions

midasBridge TeamMarch 4, 2021

Section property must be applied when performing analysis as well as material properties. midas Civil provides 'Section Properties' function to define various section shape of structures. Section properties function has an option to define a geometry shape and to calculate section properties for the analysis. And also it has an option for the design feature in midas Civil. Therefore, you can use section properties function on your purpose.

Why are the Losses of Prestressed Concrete Given by the Software not Match the Manual Calculations?

midasBridge TeamFebruary 4, 2021

Prestress does not remain constant with time. Prestress loss is nothing but the reduction of initial applied prestress loss to an effective value. Loss of prestressing affects the strength of members and also significantly affects the member’s serviceability. Prestress loss is classified into two types:

How to Add Horizontal Moving (Live) Load

midasBridge TeamJanuary 21, 2021

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.

How to Add a Transverse Moving Load?

midasBridge TeamNovember 24, 2020

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.

Lane Element and Cross Beam Methods for Moving Load Distribution

midasBridge TeamNovember 11, 2020

The difference between lane element and cross beam element for vehicular load distribution is in considering the transverse rigidity of the system and the kind of model generated (line, plate, or grillage model)

PSC Girder Bridge Assessment as per CS454

This 1-hour course will cover the moving load analysis and assessment design of a PSC girder bridge. Attendees will get many valuable tips on the common assessment design process of PSC bridges as per CS454.

 

In midas Civil 2020 v2.1, PSC bridge assessment as per CS454 has been newly implemented. During the online session, moving load analysis with All Model 2 and special vehicles will be demonstrated. Using the analysis results, assessment load effects and assessment resistances will be obtained, and they will be verified using adequacy factor and reserve factor. Ultimate limit state (flexure, shear, and torsion) and service limit state verification are provided in the tabular format and MS excel report.
