1. Addition of Grillage Model Wizard

Model > Structure Wizard > Grillage Model Wizard

Grillage Model

Multi-Cell PSC Box Bridge

The Grillage Model Wizard enables us to rapidly generate grillage models for the analysis and

design of multi-cellular decks. This feature can be applied to straight, curved and skewed

bridges. Integral, bearing and hybrid types are supported for the sub-structure. The traffic

lanes are automatically defined for moving load analysis. Using the Grillage Model Wizard,

tendons for longitudinal girders and reinforcement for longitudinal girders and bent cap can be

entered.

4. Wood-Armer Moment Calculation for Plate Elements

Results > Forces > Plate Forces/Moments

Wood-Armer moment calculation is one of the most popular design methods that explicitly

incorporate twisting moments in slab design. By using Wood-Armer moments in midas Civil,

accurate reinforcement quantities can be calculated. Wood-Armer moments can be calculated

for any direction of reinforcement in the top and bottom faces of slabs.

Mesh generation feature has been newly implemented for slab and wall members. Generated

mesh elements are fully compatible with analysis and design features. Automesh considering

interior nodes, elements, and openings is available.

Auto-mesh dialog box

Using the Auto-mesh Planar Area

function, we can generate

meshes on areas of various

shapes. In order to specify the

area, select the corresponding

Nodes, Line elements, or Planar

elements.

Using the Map-mesh 4-Node

Area function, we can generate

regular mesh shapes for any area

of 4-nodes. We can specify the

number of divisions for the X and

Y-axis separately.

Span-oriented input type for Beam Wizard has been newly implemented. In the new version,

beam elements with different spans can be rapidly generated.

Type 1: Generate beam elements based on the beam length. Beam elements with different

lengths can be generated simultaneously. (Ex. 5.0, 3.0, 4.5, [email protected])

Type 2: Generate beam elements based on the distance between the nodes and the number

of repetitions.

Inertial forces resulting from response spectrum analysis can be converted to nodal loads in th

e specified load case. The procedure is as follows:

In the “Nodal Results of RS” table, right-click and select “Convert to Nodal Load.”

In the “Convert to Nodal Load” dialog box, select the desired RS load case and Mode.

The “Combined” component of Mode represents modal combination results.

Select or create load case to generate the nodal loads.

Model > Boundaries > Elastic Link

Analysis > Perform Analysis

Stiffness of rigid type elastic link is now produced in the analysis output file (*.out).

Guideline for the modeling of fixed bearing supports:

An Elastic Link is frequently used for the modeling of a bearing that connects the

superstructure and the substructure. To represent a movable direction and a constrained

direction, the stiffness of the Link is entered as 0 or infinity. When the stiffness for infinity is

not appropriate, errors can be encountered. If the stiffness is too small, it cannot represent

the infinity properly. If the stiffness is too large, the analysis result can be distorted (ex. a

very small horizontal reaction being multiplied by a stiffness too large in the case for a

curved bridge).

To avoid this problem, we recommend 10e5 times the largest stiffness of the entire structure

as the infinite stiffness.

Shading option for solid and planer elements has been newly implemented. With this option,

the user can adjust the transparency level of the shading display.

Random element color can be automatically assigned corresponding to the type of element,

material, or section.

For pre-generated elements, assign a random element color for a particular property by clicking the [Random Color] button.

For newly created elements, assign a random element color to each of the properties by clicking on the “Assign Random Color” option.

In the old version, if a structure group “Seg5-1” is newly created, it would be placed at the bottom of the group list.

In Civil 2010, , the user

can change the group

order relevant to the

construction sequence.

Model > Group > Define Structure (Boundary / load / Tendon) Group

Automatically arrange the list of groups in alphabetical order, or manually change the order of

the groups as desired.

This feature helps the user to quickly organize and better understand the group data especially

for the construction stage analysis.
