Integrated Column Code Checks in ADAPT-Builder

The latest release of ADAPT-Builder (22.0.1) includes an integrated concrete column code check feature that allows users to easily check concrete columns for code compliance. Utilizing the ACI 318-19 or ACI 318-14 design code, the code check feature will perform capacity checks for bending, axial, and shear loading on the column against the demand forces using the PCA Load Contour methodology.

Results, including the Axial Capacity, Utilizations, Design Loads, and Rho for each of the columns can be viewed graphically. Additionally, a detailed XLS report showing the inputs and outputs of the design including PM diagrams, Design Loads, Detailed Report and a Summary Report for each column segment can be created.

How Do I Change the Slab Local Axes?

RISAFoundation has the ability to change the Local Axes for slabs. This is useful when you have a slab that is skewed from the global axis. RISAFoundation will perform the sliding and overturning checks based on the skewed local axis. You can access this ability from the Slabs spreadsheet and from the Slab's Properties dialog: With this capability you can change this axis so that the results can be more flexible to your structure’s layout and geometry…

How to Account for Axial Loads in your RISAConnection Designs

With the new RISAConnection version 2.0, users now have the ability to design all connections for axial forces as well as the shear and moment forces. Entering Your Load: For beam to column or beam to beam connections, simply enter your axial force under the Loading section of the Connection Properties dialog. For vertical brace connections, enter the beam axial force as the Beam Axial Load entry under Loading, and the brace axial force as Brace Axial load. Sign Convention: RISAConnection uses the same sign convention as RISA-3D and RISAFloor. This is so the loads transfer properly if you are utilizing the program integration. Compression forces are positive (+) and tension forces are negative (-). Axial Load Minimum Threshold: To account for axial loads and shear loads, RISAConnection will often take the resultant of these two as the available load to compare to the capacity. This can expand the limit states checks. In cases where the axial load is less than 5% of the shear load, the axial load will be assumed to be zero and the limit states will look identical to that in version 1.1. Moment Flange Force: Axial loads in moment connections are considered through the flange…

Include Transfer Forces in Vertical Brace Connections

RISAConnection assumes by default that your vertical brace connection is a one-sided connection without any outside influence or load transfer from other connected elements. Using this assumption, the design shear and axial force at the beam to column sub-connection is determined using simple statics per the Uniform Force Method in the AISC Steel Design Manual. However, it is very possible that this connection is also seeing forces from other connected elements, such as out of plane horizontal braces. You may now take these into account by entering them as the new Transfer Forces input. These inputs will be included in the final calculation of the axial and shear design forces at the beam to column sub-connection. The equations shown below are based on statics as well and combine all components of the loads at the beam to column intersection. The final load calculations are shown in detail in the Required Load Calculation report on the Beam/Column results report tab…
