Key Features

Combining structural analysis capabilities with civil engineering specific stage analysis, pushover analysis and nonlinear time history features, midas Civil provides the necessary tools for advanced modeling, analysis and design for the bridge engineer.

Intuitive Modeling

midas Civil is equipped with a wide range of advanced options that will provide you with convenient and efficiency enhancing solutions to design and modeling challenges.

Easy Modeling of Curved Bridges

Modeling curved bridge geometry in 3D was once a time-consuming and complex process for bridge engineers. But with midas Civil's special modeling tools you can now model curved bridges with an unmatched level of ease, speed, and accuracy. Modeling tools such as "Create Elements on Curve" and "Curved Element Coordinate System" have been implemented specifically to simplify the modeling of curved geometry. Now modeling those curves will be one of the easiest parts of your project.

Works Tree Menu

Since finite element models contain an extensive amount of data entry and output it is very important to keep all of this data organized for easy reference and modifications. A highly advanced and distinct feature of midas Civil is its Works Tree Menu, which organizes all or your pre and post processing data in a clear and accessible format. Everything you create and define is automatically recorded and displayed in the Works Tree Menu so that you can easily keep track of the progress of your project. This menu also enables you to seamlessly make changes to your project data. Thus you will be able to make adjustments and changes to your project as soon as the need arises.

Cross Section Function for Composite Bridges

The modeling of composite sections is another aspect of bridge design that used to require a significant amount of time and effort. midas Civil has a “Special Composite Section” feature that enables you to capture the non-composite and composite behavior with sequential deck pours during construction for steel composite and PC girder bridges. This feature will enable you to create an accurate and detailed simulation of a composite section construction through a very fast and simplified process.

Comprehensive Seismic Analysis

midas Civil is equipped with multiple seismic analysis functions that perform the required bridge seismic design checks. Response Spectrum, Pushover and Time History analysis can be performed with built-in definitions for the AASHTO LRFD Design code.

Determine capacity with built-in pushover analysis

midas Civil has an integrated pushover analysis procedure to ensure that you will be able to all the necessary input data to perform an accurate pushover analysis. The procedure includes the defining of pushover cases and hinge properties as well as the assigning of hinge properties to the elements of your model. Once the pushover properties are defined midas Civil's advanced Skyline and Multi-Frontal Solvers will perform a speedy analysis that typically takes under a minute.

Time History Analysis made easier than ever before

midas civil includes a database of built-in design earthquakes from which you can conveniently select the design earthquake that best suits your project. midas Civil also includes input menus that enable you to simply define the hinges as per the hysteretic system. The results are then generated in both graphical and text format.

Bridge Wizards

midas Civil's unique bridge wizards greatly expedite the modeling of complex and conventional bridges. With the use of these wizards you simply need to enter the geometry and loading properties and wizard will automatically create the entire model for you. These wizards have the potential to save you many hours of time that would have been spent tediously creating the model yourself.

Wizards available for conventional bridges include span by span construction, incrementally launched bridges, and post-tensioned bridges with special construction stages such as balanced cantilever construction. Wizards for complex bridges include cable stayed, suspension and segmental bridges.

Moving Load Analysis

Special considerations as per AASHTO LRFD are duly implemented for moving load analysis. For load rating, more than 2 wheels in an axle can be defined. The “Moving Load Tracer” feature displays the wheel locations responsible for the worst case scenario and easy verification. Concurrent forces vital for plate girder bridges are automatically calculated along with the normal envelope for live load results.

Construction Stages

The construction stage analysis feature allows for easy simulation of the stages. The behavior of the structure can be simulated to check for structural integrity during each construction stage. Creep and shrinkage properties of concrete and the change in elastic modulus with time can be defined to consider the time-dependent effect. Thus you can effectively simulate the conditions of each stage of the bridge construction.

Auto Design and Load Rating

Midas Civil can be used to perform design checks and load ratings as per the latest AASHTO LRFD 6th edition. Detailed design reports are generated in spread sheets for verifying with hand calculations. Design checks can be performed for strength limit state and service limit state by defining combinations from AASHTO LRFD automatically. A detailed excel report with step by step descriptions of design checks can be generated as well.

Report Generation

midas Civil’s state of the art report generation includes features such as graphical generation which allows you to define the function with respect to either time or distance. The intuitive drag and drop feature allows you to conveniently copy images and result tables directly from the program to your MS Word report. All of the data entered in the report can be modified and saved by the user in MS Word format without any limitations. Also, all result tables can be seamlessly exported to Excel.
