A specific construction stage pertaining to a structural model can be exported as a final stage. With this option, users can perform time history, seismic or moving load analyses at various stages of construction. |
The Any construction stage can be easily deleted, or new stages can be inserted. The order of construction stages can also be revised. The works tree allows you to systematically check and revise the structure and loading conditions for each construction stage. |
Define each stage based on sequential structural changes reflecting erection and dismantlement of temporary structures, varying boundary conditions, etc. Define timing steps representing the timing of loading and unloading specific load cases within a given construction stage, without any change in structure |
The construction stage analysis feature allows the user to specify activation and removal of elements with varying maturities, changes with boundary conditions and changes with loadings during the construction sequence. As such, construction stage analysis reflects the erection and dismantlement of temporary structures, complex bridge analysis, construction stage analysis of PSC box bridges reflecting temporary structures, and heat of hydration analysis based on the concrete pour sequence. |
midas Civil genera automáticamente un modelo de análisis transversal a partir del modelo de análisis global. Al seleccionar un punto en la dirección principal, el wizard genera un modelo de marco bidimensional, que intersecta el punto, generando las propiedades de la sección para el análisis. Además de las propiedades de la sección geométrica, el usuario también puede asignar cargas (ej. Cargas muertas, cargas vivas, etc.), tendones y refuerzos. |
El trazador de cargas móviles determina la ubicación de una carga en movimiento que impone las fuerzas máximas de los miembros. Las fuerzas y tensiones en los miembros de la viga que resultan de análisis detallados de elementos individuales se pueden verificar con diagramas de viga. Con los modelos de placa, la suma de la fuerza de dirección local combina las fuerzas nodales de la placa o elementos sólidos y calcula las fuerzas de los miembros en las posiciones especificadas. |
Para los análisis de carga móvil, midas Civil proporciona una base de datos de cargas vehiculares estándar. Los usuarios también pueden definir cargas vehiculares separadas. La base de datos de carga móvil disponible incluye: - Estándar - AASHTO LRFD - PENNDOT - Canadá - BS Eurocódigo - China - India - Taiwan |

Analysis of Composite Girder BridgeOverviewThe prime concern in integral bridges is the effects of temperature variations on the deformation of bridge deck. Expansion and contraction of the bridge deck affects the backfill soil adjacent to the abutments. Backfill compaction due to deck expansion and soil slide due to a deck contraction is repeated. Due to the repeated backfill compaction and soil slide, the modulus of subgrade reaction and the pressure distribution of backfill vary with depth. For this, Midas Civil provides Multi-linear type point spring support. Also the program can automatically calculate the soil stiffness by entering the required data such as soil type and subgrade reaction.

Production of maximum stresses at the left/right sides on a transverse cross section of a curved bridge. Production of member forces of the structure when the maximum force due to a moving load is applied. Production of various diagrams (member forces, stresses, displacements, reactions, etc.) for reviewing analysis results for each construction stage (stages & time steps)Provision of animations of analysis results for each construction stage. Report on prestress losses due to curvature and time variation. |
Tendons can be defined at any location and checked with transverse Short-term prestress losses are considered for the effects of anchor slippage of tendons, friction between tendons and sheaths, and elastic concrete shortening. Long-term prestress losses are considered for the effects of creep, shrinkage Variation of prestresses in tendons

midas Civil automatically generates the composition of construction stages and models for MSS/FSM bridges. |
An FCM bridge model with construction stages can be automatically generated after defining only cross sections, tendon placements and bridge configuration data. Sections and tendon placements are defined within the wizard. The wizard defines the entire bridge model including piers and key segments. Capable of real-time display of construction stages automatically generated by the wizard FCM Bridge Wizard. |

Capable of real-time display of construction stages automatically generated by the wizard FCM Bridge Wizard.Using the ILM bridge model wizard, enter the number of segments and the corresponding data to generate the entire bridge configuration. Basic construction stages (activation of segments) can be automatically generated on the basis of the number of segments entered. Using the bridge data, the number of days for the construction of each segment and each launching length, a detailed construction stage for each launching stage (with activation and deactivation of supports) is automatically generated. |
Composed of flexible cables. The suspension bridge wizard in midas Civil automatically calculates the cable coordinates and tensions of the final structure. Also, using 3D elastic suspension line elements and equivalent truss elements, midas Civil can consider nonlinear characteristics of the cables. It supports geometric nonlinear analysis as well as construction stage analysis. |
