If you draw only half of the bracing system in SAP2000, make sure you are properly accounting for symmetry. In structural analysis software like SAP2000, you can sometimes model only half of the structure if it is symmetrical, and the software will apply the loads accordingly to both halves.
When you encounter the warnings in ETABS stating that “THE STRUCTURE HAS NO (UNDERSTAND) MASS; NO EIGEN MODES CAN BE FOUND” and “NO EIGEN MODES CAN BE FOUND,” it indicates that the software is unable to compute the dynamic properties of your structure due to a lack of defined mass. This...
You indicated using a bending stiffness modifier of 0.15 for both frame elements and spandrels. However, if the effective stiffness of the spandrel is lower due to its connection details or geometry (e.g., door openings), it could lead to increased deflection and thus higher moments and shear...

While ETABS remains a leading choice for high-rise structure analysis in Canada and the US, several other software options like SAP2000, SAFE, RISA-3D, RAM Structural System, and Midas Gen are also widely accepted within the industry. Each software has unique features that cater to specific...
The “Error 9: Subscript out of range” message in SAP2000 typically indicates that the program is attempting to access an array element or a collection item that does not exist. This can occur due to various reasons, including corrupted files, issues with user settings, or problems with the...
The display on screen might reflect real-time calculations or adjustments made during the design process, while the summary table may represent finalized values after all checks and balances have been applied.
The software allows users to set preferences that can affect how results are...
1.Start by opening your existing ETABS model or create a new one.
2.Go to the “Define” menu at the top of the interface and select “Supports.” This opens the support definition dialog box.
3.Click on “Add New Support” to create a new support type.
4. In the support type options, choose “Roller”...
When designing concrete-filled composite columns in ETABS, particularly in version 22.1, several factors can contribute to the errors you are encountering.
1. In your case, a concrete-filled composite column consists of a steel section filled with concrete, which enhances its load-carrying...
While Slide RuleEra’s site may no longer be active, there are numerous alternative avenues through which you can access Waddell’s 1916 text “De Pontibus”. The combination of digital libraries and community resources should provide ample opportunity to locate this valuable engineering reference...
1. Scia Engineer is a powerful structural analysis and design software that provides various tools for modeling, analyzing, and designing structures
2. While Scia Engineer may not have a dedicated module specifically for shear wall design, you can still effectively utilize its features for...
When working with SAP2000 and attempting to change the section of a beam during staged construction, there are several steps and considerations that must be taken into account to ensure that the changes are applied correctly
1. Ensure that your model is set up correctly. You mentioned creating a...
