ADAPT-PT/RC Version 21.0 is now available!

New Design Code: AS3600 - 2018

ADAPT-PT/RC has been updated to include the latest Australian - AS3600 (2018) concrete design code. The provisions in this design standard that have been included in ADAPT-PT/RC include but are not limited to:

Utilization of a parabolic strain-stress curve per requirements of section 3.1.4, for design purposes this curve is modified such that the maximum equals 0.9*f’c.

Load combinations based on the requirements of section 2.5.2 in conjunction with AS/NZS 1170.
Crack control in prestressed sections (beams and one-way slabs) is compliant with section 8.6.3.
Crack control in prestressed sections (two-way slabs) is compliant with section 9.5.2.3.
Service deflections in cracked state using the properties of effective moment of inertia based on Eq.8.5.3.1 of the code.

Openings

ADAPT-PT/RC now includes an option to model openings, or penetrations, near columns and evaluate the punching shear strength of the slab. This new feature is available for the following design codes:

ACI-318-19/14/11/08/05/99
CAN-A23.3-14/04/94

Openings in RC and PT two-way slabs are critical factors that impact the punching shear strength of the slab. Openings next to columns reduce the concrete area that resist punching shear and can significantly reduce the slab’s shear capacity. Therefore, the presence of openings must be considered in punching shear design.

Openings that are included in the analysis can be viewed in a tabular report by generating the Support Openings report found in the Tabular Reports – Compact tree of the Report Generator.

Reporting Base Shear Reinforcement

When utilizing base shear reinforcement (stirrups) in a model, it is necessary for these elements and their information to be included in the report. As such, a user can access the base shear reinforcement report within the Report Generator.

Once selected, the base shear reinforcement report (which includes legs, rebar sizing, spacing, length and area) is included.

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…

Governing Load Combinations for Shear in Concrete Columns

For concrete column members, the load combination producing the maximum shear code check is reported in the Detail Report and corresponding Results spreadsheet. Since concrete is evaluated based on a batch solution, this can be useful when shear governs the design. RISAFloor Concrete tab of the Column Results spreadsheet: Column Detail Report: RISA-3D Concrete Columns tab of the Design Results spreadsheet: Column Detail Report: Shear is checked in both the local y- and z- directions, so the reported load combination in RISA-3D and RISAFloor might not necessarily correspond with the highest applied shear force. This is because the shear capacity can differ in each direction based on the geometry of the column. RISAFoundation For pedestals in RISAFoundation, the load combination producing the governing shear check can be found for both pedestals drawn as part of a slab element and pedestals that are designed as part of a footing support type. Pedestals Design Values tab of the Pedestals/Posts Design Values spreadsheet: In addition, the pedestal detail report will show the governing load combination for the shear check in each direction. In addition, the pedestal detail report will show the governing load combination for the shear check in each direction. The governing…
