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.

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.
