ADA models the soil layers as lateral spring elements to calculate the resistance of foundation against horizontal loads and lateral deflections. But these springs are not considered in designing of structural axial load capacity of pile. However there is an option to modify the buckling length of pile by user.
Yes, we have currently completed seismic analysis which will be released with the SP1 (set to be available before the end of 2015) and development is in progress for the pushover analysis and non-linear time history. All design aspect of the S6-14 code are already up-to-date and have been available since the release of ADA 2016.
Though we don’t have the integral abutments model in our “Pier, Abutment and Retaining Wall Generator”, we do however, have rigid link and plate elements to transfer all of the forces from deck to abutments. Converting a simple model from our already existing generator to an integral abutment can easily be achieved with some minor modifications using the elements in ADA.
All of the nodes on the wing walls can be defined as elastic supports according to user’s preference. The springs are not created in an automatic fashion but with a few simple clicks the node can be changed to spring elements.
In the member properties dialog box there is an option to define the behaviour as Tension or Compression only.
ADA has an automatic load combination generator which considers all of the load factors according to user defined code. Depending on the loads you select/define the combination generator will create all the possible permutations based on the code desired.
ADA can design or verify the member according to the specified code. If the user wants to check the code violation of a member, it can be performed by code verification option in ADA. The member failing will be highlighted in yellow in the spreadsheet and will display the reason it is not passing code checks.
There is the possibility of defining the lane position in transverse direction. This can be done by automatic moving load generator of ADA. By selecting a 3D moving load scenario in the moving load generator, ADA will produced the “trucks” moving transversally between the lanes.
Yes, ADA automatically generates these shapes on the pre-stressed beam model.
ADA has the possibility to define sequential post-tensioning based on staged construction. The user can define several stages of post-tensioning for the cables with a number of cumulative days associated to each stage of the construction phase.
Yes, linear spring elements represent the soil behaviour in the model. The stiffness of springs is calculated based on the soil properties.
Within ADA we can define the difference between an internal and external tendon. All the coefficients related to the loss of post-tension can be modified.
