Modeling the geometry of curved bridges can also cause considerable challenges.

midas Civil is equipped with functions such as “Create Elements on Curve,” and “Curved and Element Coordinate System” that enable engineers to easily model curved sections.

 

 

 

 

Integrated bridge wizards

Simple solutions for complex challenges

 

Bridge modeling often consists of many repetitive and time consuming steps. This is especially the case for larger bridge projects that consist of hundreds of nodes and elements.

midas Civil has exceptional bridge wizards that will enable you to model all bridge types at a highly accelerated rate.

You will be able to create your bridge models quickly with standard definitions such as loading, construction stages, tendon profiling and boundary modeling.

The wizards have been developed with a simple and straightforward format so that even engineers without expertise in finite element analysis can use them.

These bridge wizards also contribute to higher quality results. The wizards enable engineers to create complex models with unprecedented ease and accuracy; thus the possibility

for modeling errors is greatly reduced and the results will be more accurate and reliable as well.

Multiple Analysis Options

The only analysis tool you'll ever need

 

midas Civil is equipped with functions for any bridge analysis that you will have to run, thus eliminating the need for multiple software programs.

For example, many engineers use separate programs to run superstructure and substructure analysis.

This limitation often leads to significant losses in time, efficiency, and accuracy. midas Civil can do both in the same file.

Just imagine how convenient it will be to have one program that handles every analysis for you: No more going back and forth between several programs.

Less time spent inputting data. More time to spend on other priorities.

 

 

Time History Analysis    Pushover Analysis 
Time History Analysis is used for the seismic design of high-end bridges as well as heavy structures being built on relatively soft soils. midas Civil has multiple functions that greatly simplify and streamline this highly detailed analysis.   Pushover analysis is essential in seismic design because it greatly reduces uncertainty and conservatism. midas Civil enables you to perform an accurate pushover analysis through the defining of hinge properties as well as pushover cases.

Stress in Section   3D PM Curve
midas Civil enables you to view the levels of strain for each section and element of your model through colored contours. This medium of display is much more efficient and aesthetic than typical spreadsheets and graphs.   The study of axial force moment interaction is required to design columns and beam-columns. midas Civil displays the axial force moment interactions in 3D graphs with corresponding spreadsheets for fast and easy reference.

Built-in formulas

Minimum effort. Maximum results.

 

 A detailed bridge analysis consists of countless repetitive calculations. In today's modern design practices, hand calculations and spreadsheets are quickly becoming outdated.

Many design firms have invested in high-powered bridge software to stay competitive. 

 

midas Civil is a leading choice of bridge software because of the accuracy and accessibility of its built-in formulas.

You merely need to enter the preliminary data and parameters and midas Civil will automatically perform all the detailed and repetitive calculations.

For example, when performing soil structure interaction, soil supports need to be generated which require calculation of spring constants.

This process leads to time consuming calculations that are prone to errors.

midas Civil has embedded bridge wizards, automatic support springs for soil and easy modification features that drastically simplify this process.

Hundreds of calculations are performed in a matter of seconds. The program also seamlessly generates the corresponding graphs and tables, thus eliminating the need to create graphs through excel.

 

      img_civil_023         Non Linear Soil Spring Support
Time History analysis requires engineers to account for nonlinear behavior of soil. This is mainly done through the assigning of nonlinear soil spring supports to your model. midas Civil has functions specifically designed for the defining and assigning of these supports.
 Soil Structure Interaction
Considering the effects of Soil Structure Interaction allows for valuable benefits such as increasing the effective damping ratio of your structural design, thus you to make more optimized designs that account for lower and more realistic projected oscillations of the structure. midas Civil has various interface element options that enable you to accurately simulate Soil Structure interaction.
 Pile Axial Forces
It is essential to have a complete summary of the pile axial forces for the foundation of every bridge project. midas Civil's post processor creates contour diagrams as well as corresponding spreadsheets that provide an organized and accurate display of results for all pile axial forces.

Stonecutters Bridge

The concept is for a cable-stayed bridge with a twin aerodynamic deck suspended from two 295m-high single pole towers. These towers will have bases measuring 24m x 18m tapering to 7m diameter at the top, and the deck will allow a navigation clearance of 73.5m over the full entrance to the Container Port. This sets a record of being the world’s 2nd longest cable stay bridge to date for which full erection engineering was carried out.
