The world of design and construction continues to take leaps in advancements, leveraging technology.
Pre-construction processes become much streamlined with the use of Building Information Modeling (BIM). Whether it is the architecture, mechanical, electrical, or structural part of a building, everything vertical is now handled with advanced software applications and on-site technologies.
A study from the International Journal of Research Publication and Reviews shows that the use of software in various aspects elevates project outcome standards, leading to greater client satisfaction.
There is so much to talk about, different software applications, elevating the conventional standards of every construction phase.
Valued at USD 9.6 billion in 2023, the global BIM market shows huge potential for further acceptance, reaching USD 37.67 billion by 2032. However, this blog will focus on the structural aspect of a built environment.
We will be discussing the ETABS software, a renowned name in the area of structural engineering.
Here’s everything you need to know about it. A brief intro will help you understand better.
ETABS stands for “Extended Three-Dimensional Analysis of Building System”, and was rolled out by CSI- Computer & Structures Inc. in 1975.
Can you imagine the decades-old software still finds extensive use and is a preferred choice for structural engineers? It was the first specialized solution for structural analysis which gradually evolved into an industry standard and serves modern structural engineers effectively.
ETABS is often compared with its competitor from Bentley Systems, STAAD.Pro.
However, it stands out for a couple of impressive factors, which are unlikely for STAAD.Pro. They are:
The software is currently the primary tool for engineering firms across 160 countries. It underscores the value it delivers even when having a competitor from Bentley Systems.
We will be diving deep into the key features of ETABS, exploring how those help in advanced structural modeling and earthquake engineering.
Here is a list of the key features of ETABS and how they benefit:
Starting out with its intuitive, easy interface, ETABS comes with a,
As the solution provides multiple capabilities, such as designing, modeling, analysis, and visualization, things may get complicated with multiple user interfaces.
However, that’s not the case here; the ETABS software comes with a fully customizable user interface. The single user interface can be moulded for various activities, with an unbounded number of model windows, manipulation views, and data views.
With the solution’s story-based view, engineers can easily navigate across stories, isolate specific storeys during analysis, and a lot more can be done.
It offers multiple views of the model, from varied perspectives, like 3D, plan, section, and elevation. This ensures seamless integration of various structural elements, reducing rework.
The developers are mindful of the fact that multiple views can be overwhelming and distracting. Hence, they arrange it into specific tabs for quick toggling between views.
Since the tool is renowned for structural analysis, here is how it justifies that.
Analysis involves a lot of data, which should be organized and readily accessible. ETABS segregates data from each category of structural elements into interactive tables.
The tables have basic to advanced sort and filter options, which offer substantial benefits. Additionally, the software’s interface allows viewing these tables while modeling for better accuracy.
There is no way we can leave this one; structural engineers reading this blog can relate.
It is one of the most talked-about features that allows a structural engineer to fly-through and quick rotate the model for flexible viewing. This is done through DirectX Graphic’s unique hardware accelerated graphics.
When working on large civil engineering projects, it allows for quick transitions between different sides of the model.
The analytical model is the backbone of ETAB’s structural analysis capabilities.
For specialized analysis, engineers can generate an analytical model from the parent model. This model contains the connectivity of joints, frames, and shells, which is displayed in the analytical view. Based on actual connectivity and constraints, the model shows an accurate simulation of the structure’s behavior and aids in performance based design.
The intelligent system identifies connectivity issues and missing restraints to easily modify properties of the ETABS model before the structural model integrates with architectural or MEP models.
The interoperability of the ETABS allows Revit professionals to work on a shared model, hence avoiding re-modeling.
The physical model is a realistic representation of the structure with beams, slabs, walls, and columns.
The insertion points and offsets are clearly visible, which helps engineers to understand the structure and conduct reviews seeking improvements. Modeling also gets simplified as analytical segmentations are automatically managed by the software.
Overall, the feature reduces manual input of geometrical data, which leads to fewer errors and rework.
Load distribution is a core element of structural engineering. ETABS provides a range of meshing tools that allow for precise structural behavioral analysis with various loads, the most important being the wind load.
ETABS supports heavily irregular and complex shapes through custom meshing tools, hence providing more accuracy of real-world structural layouts.
While there are options for automatic modeling, engineers can switch to manual meshing in case fine detailing is needed. Custom meshing optimizes mesh density across the model, enabling accurate calculation of load distribution, stress, and response spectrum analysis to better understand seismic loading.
When working on structural projects, engineers need to ensure compliance with the applicable codes.
Thankfully, ETABS comes with an in-built library which is in compliance with the US and international standard sections for standard concrete, steel, and composite section properties. There is also an integrated application called the Section Designer, a part of the SAP2000, CSiBridge, and, yes, ETABS.
The application facilitates accurate modelling and analysis of critical cross-sections, and engineers can place reinforcements in custom shapes with ease.
So, these were some of the key features that make ETABS a premier choice for structural engineers across the world.
These features of ETABS software offer several benefits to users, unlike other software packages in the market. Here are some of them:
ETABS aims to simplify the complex processes that structural engineers go through.
Built-in drawing utilities are standard drawing and drafting tools. Alongside these tools are industry-standard shortcuts and controls that enhance compliance and modeling experience.
This built-in library, coupled with the intelligent snaps, further simplifies model generation with automatic detection of intersections, extensions, and complex geometrical relationships.
The software keeps records and generates detailed reports of tasks performed for a project.
Users get essentially three types of reports:
The automatically generated report by ETABS offers a comprehensive view of a project’s structural analysis. It includes detailed structural data with story and grid data.
These are highly customizable reports, where users choose what to display on the report.
The system allows users to select specific beam forces, column forces, and other required information. Users get a dialogue box where they can specifically choose the output by ticking or unticking story, lines, modals, points, etc.
This allows for highly customizable reports required in specific scenarios.
Finally, the third type is generating reports with use of this plugin called CalcTree.
The plugin uses Python scripts, which allow users to replicate or make changes to existing report templates. When required to generate structured tables, such as Load Tables, Model Definition Tables, and Analysis Results Tables.
To master all of the features and reap the benefits, civil engineering students can go for a course.
The reason is that to make their foundation string, students have to learn manual calculations and processes in their curriculum. However, they can learn it through supplementary courses or online workshops.
ETABS is a premier software for structural design and analysis that supports the nonlinear modal method.
For civil engineering graduates, it is a must-have skill that will not only strengthen their profile but also prepare them for modern construction workflows. Learning the software will help you land a high-paying job in the field.
However, it is about mastering the thing, not just bearing a certificate.
A couple of courses you can go for come from Udemy, Class Central, and the developers themselves, CSI.
They offer helpful resources and tutorials right on their official website. Apart from that, in case of unexpected issues, you can always look forward to online forums.
Engaging with a community of other ETABS professionals will amplify exposure to industry-relevant knowledge.
ETABS is the best solution for story-based modeling, structural behavioral analysis, and seismic load calculations and simulations. The tool helps engineers visualize various load conditions, finally generating an outcome that’s tough enough to withstand natural forces.
Yes, the structural analysis and design software has an alternative known as the 'Student Version.' A license is required for using it, which is available at the official website of ETABS.
ETABS offers seamless interoperability with Autodesk products for structural engineering analysis. Particularly through Revit, it can be integrated with the entire workflow as it supports the IFC classes and other relevant file formats. Hence, no data loss during interoperability.
It is because ETABS offers more automatic features, unlike STAAD.Pro, and therefore reduces manual input and calculation errors.
