What is the Difference Between a Boundary Condition and an End…

In RISA-3D, there are numerous options for Member End Releases which should not be confused with Boundary Conditions. End releases are used to define how elements connected to each other. For example, End Releases are used to define whether a beam is carrying moment into a column. You can define the Member End Release when you create the member or you can click on the member and review the I End and J End Release Codes in the Properties Panel by selecting the three dots to the right of the empty fields. Each member has six force components at each end (axial, y-y & z-z shear, torque, and y-y & z-z bending). A good rule of thumb for connections in steel beams: Fully Fixed (Moment connection) = Both the Flanges and the Web are connected Bending Moment Released (Shear connection) = Only the Web is connected Boundary conditions define the EXTERNAL support conditions for your model. For example, a steel frame sits on a foundation and the Boundary Condition defines how the loads get transferred to the foundation. You define the restraint for X, Y, and Z translations and X, Y and Z rotations with reactions, fixed or springs. (For…

Canadian Wood Design Updates

The latest releases of RISAFloor and RISA-3D include the following updates to wood design per the Canadian codes: Wood Wall Design RISA-3D v16 and RISAFloor v12 now offer design of wood walls per the Canadian wood design codes (CSA O86-09 and CSA O86-14). The design methodology is very much like the Segmented method used by the NDS design codes. Design requires chords on each side of each full height panel. Design assumes that the areas above and below openings have zero stiffness. Only full height piers are considered to resist loading. Additionally, the design of individual panel elements is as follows: The sheathing panel is assumed to resist the in plane shear The chords are assumed to resist the overturning moment The studs are assumed to resist the axial load The hold downs are designed for the governing tension chord force at the base elevation of the wall Deflections, including the effects if hold-down elongation, are calculated per the code based equation For more information on wood wall design, please see the “Wood Wall” topic in the program help file. Structural Composite Lumber Design RISA-3D v16 and RISAFloor v12 will also now offer design of structural composite wood members per…

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. For more information about the concrete column code check feature in ADAPT-Builder, visit our Online Help file or watch the video below…
