Cable Stayed Bridge Wizard

Cable stayed bridge wizard permits generating accurate models and performing analyses of many design alternatives in a short time. Initial cable forces are calculated through Optimization for initial equilibrium state analysis. 

It also provides the Construction stage function, which enables us to reflect Creation/Deletion of elements, change in boundary conditions and loading changes that may occur in various stages of construction.

Integrated structure and bridge wizards

2D Transverse analysis model is automatically generated from the global analysis bridge model. Transverse tendons and reinforcements can be considered   484d5b9c-ae9d-4fe5-a907-981578bceccf
 
  
 
Rail Track Wizard enables the user to automatically model and load rail track interaction phenomena. Manual modeling is also available.   de03ad84-2b45-45ab-9843-cb24b0c99acd
 
 
RC Frame / Box Curvet wizard supports auto-generation of entire process required for analysis and design by simple data entry. Auto-generation of loads and combinations based on various design standards is also available. Design of reinforcing bars and strength verification of beams and columns can be done more easily   1ec76846-8546-4638-8488-a82f97d08abf
 
 
An FCM Bridge model and construction stages are automatically produced after having entered only cross sections, tendon placement and bridge information. It is capable of Real time Display of construction stages auto-generated by FCM Bridge Wizard.   65ff58dd-035c-4103-b4d5-fd13352bdba4
 
 
Common structural models such as trusses, arches and frames can be readily created using the structure wizard.
Structural bridge modeling wizards also minimize the time required to model more complex bridge structures, such as a suspension bridge or a cable-stayed bridge. This gives users the opportunity to generate accurate models and perform analyses with many different design alternatives in a much shorter time frame.
midas Civil support following bridge model wizards: Segmental Bridge Model Wizard (ILM, FCM, MSS, FSM), PSC Bridge Wizard, Grillage Model Wizard, Suspension Bridge Wizard,Cable  Stayed Bridge Wizard, Transverse Analysis Model Wizard, RC Slab Bridge Wizard, RC Frame/Box Culvert Wizard, Rail Track Analysis Wizard

Various Material and Section Properties

User can import any DXF section drawing created in CAD. Any complex and unusual bridge sections can be modeled and analyzed. A composite section with different materials can equally be modeledAccurate analysis result can be obtained by calculating the exact torsional stiffness.   f06cd7bd-a4c4-4ed9-9f28-225cc8bccc77
midas Civil has built-in Section Property Calculator, which permits users to draw sections of arbitrary shapes and calculate the section properties of unconventional section shapes.   cf79db16-145e-4a4d-8009-8c0a97c02fc8

The member force before and after composite effect can be easily computed for the Composite Girder BridgeThe grillage model of the Composite Girder Bridge can be analyze considering the construction stage before and after composite effect.The stiffness for tapered Arch Rib and Segmental Girder can be calculated more accurately.

midas Civil provides material and section databases according to ASTM, AISC, CISC, CSA, BS, DIN, EN, UNI, IS, JIS, GB, etc. User-defined materials and sections can also be defined in midas Civil. A total of 37 different section shapes including steel-reinforced concrete composite section shapes can be applied to line elements. Additionally, midas Civil includes a Section Property Calculator, which is used to calculate the section properties of unconventional section shapes.

Complete Load Library

Nodal Masses

Lumped translational mass and rotational mass moment of inertia are specified at a particular node.

 

Loads to Masses

Vertical components (loads acting in the Z-direction of the GCS) of the entered loads are converted into masses, which are considered as concentrated mass data.

 

Consistent Mass

midas Civil converts consistent mass into distributed masses. Consistent mass is calculated using the shape function to derive the stiffness matrix. Off-diagonal mass terms are considered and, unlike the lumped mass, the inertia coupling effect is considered. Therefore, results using consistent mass is more accurate than the lumped mass, however the numerical computation takes more time to complete.

 

Self-weight to Mass

The masses of the elements included in the model can be automatically converted into lumped masses or consistent masses in midas Civil for dynamic analysis or computation of statically equivalent seismic loads.

midas Civil performs time history analysis where time history loads or sinusoidal loads can be applied to nodes.For response spectrum analysis, select a response spectrum from the seismic database in accordance with a governing standard. The built-in design spectrums based on international codes are as follows: IBC2000, UBC, NBC, Eurocode-8, China, IS1893, Taiwan, Japan, and Korea
