Integration between RISA-3D & ADAPT-Builder for Podium Buildings

ADAPT-Builder v21.0.1 includes the option to import reactions from a RISA-3D model. The program will import the superstructure reactions and loading as point and line loads. The B3D Import Wizard allows you to choose which load cases to import and gives you the ability to map the loads to existing load cases in the ADAPT-Builder model. The import of reactions/loads from RISA-3D can be used in any model and is available for all design codes. Loads exported from RISA are in imperial units and will be converted to the unit system of the ADAPT-Builder model upon import. Using RISA-3D’s new exchange file format (.B3D file) you can efficiently import reactions into ADAPT-Builder using the B3D Import Wizard. Integration with RISA-3D After solving a model in RISA-3D the user can go to File>Export and choose to export an ADAPT-Builder File. This will create a B3D load transfer file for you to import to ADAPT-Builder. Once you have the B3D transfer file you can simply open the model in ADAPT-Builder that you want to import loads to. In the Loading ribbon, click the Import from RISA icon. The B3D Load Import Wizard will open. Upon opening the Load Import Wizard, you can…

ADAPT-Builder: Fixing Instability Warnings Due to Multiple Slabs

When working with ADAPT-Builder, in some models users may encounter an instability warning due to multiple slabs on a single level. This can be frustrating, but we're here to help! The root cause is typically related to insufficient boundary conditions allowing unintended translation or rotation. Below, we’ll walk through how to diagnose and resolve this issue effectively. Step 1: Diagnose the Issue View the Deflections: Using the Results View, display the Slab Deformation for the X- and Y-Translation. If one slab is deflecting significantly more than the other, this indicates instability. Check Boundary Conditions: Instability often occurs because there’s nothing preventing the slab from translating or rotating out of plane. This behavior occurs because the slab lacks adequate constraints to prevent it from translating or rotating. By default, ADAPT-Builder assigns automatic boundary conditions to prevent this from happening, but when multiple slabs exist on a single level, these may not be sufficient to stabilize the system. Step 2: Understand Automatic Boundary Conditions ADAPT-Builder applies automatic boundary conditions to the model, including: Analysis/Design Options: Defines the boundary condition at the base of the supports. By default there is no fixity in the X or Y direction. Analysis Options: Defines the boundary…

ADAPT-Builder Version 22.0.2 now Available!

ADAPT-Builder Version 22.0.2 is now available and includes the following enhancements: Added wall design per ACI 318-19 code. Improved the Wall Design Manager to only consider strength combinations. Added option to automatically update wall section reinforcement when designing walls. Implemented a new Feedback button that allows the user to request improvements to the software. Improved ADAPT Wall Design Manager In ADAPT-Builder v22.0.2 the integrated wall design capabilities of the ADAPT Wall Designer have been improved to include the implementation of the ACI-318-19 design code. The design of concrete shear walls can be done with or without special boundary elements for seismic lateral resisting systems. The user has the option to perform a Code Check or a Design of shear walls within an ADAPT-Builder model. A code check allows the user to define the reinforcement within the wall and the program will check whether the assigned reinforcement satisfies code provisions for minimum reinforcement, bending, and shear capacity. If a user chooses to Design the walls, the program will iteratively design the reinforcement for the walls within the user-defined design constraints to satisfy code provisions. Codes: The ADAPT Wall Designer has been implemented for ACI-318-19 and ACI-318-11 design codes. For more information…
