ETABS or Extended Three-Dimensional Analysis of Building Systems is used to evaluate various structural designs that include skyscrapers, steel and concrete structures, low and high-rise buildings, parking garages, portal frame structures, and more. Developed by csiamerica, ETABS is a structural analysis and design software that covers all areas of the design process and prepares schematic drawings.
The software unfolds more than 45 years of research that ensures seamlessly integrated analysis and design of building systems. It provides a single user interface to perform various functions such as modelling, analysis, design, and reporting with no limit to the number of model windows, model manipulation views, and data views.
To make structure design more robots and secure, a proper analysis is required. Depending on the type of structure, engineers use different tools to prepare the building design. ETABS is an easy-to-use software, helpful in the construction and stimulation of intricate patterns. With the latest ETABS software, you will find the following features to use in structure designing:
It is easy to convert CAD drawings into ETABS models. Interestingly, ETABS also provides its own CAD-type tools for the generation of models. While using the software, you can access highly sophisticated modelling and analysis options. Moreover, you can perform a dynamic evaluation of multiple towers from a common podium base, staged construction analysis with time-dependent material behaviour, soil structure interaction, rigid or flexible floor diaphragms, and more.
With certain modelling features, it becomes easy to create analytical models and simulate advanced seismic systems. It provides the following options for modelling of structural system:
For dynamic analysis, IS 1893 (Part 1): 2016 is adopted. Users can determine the natural timeframe or periodicity of the design using modal averages. Furthermore, they can also find out the optimal reaction rate of the building with a spectrum acceleration curve. By analysing the results and verifying the mistakes, you formulate an outcome.
One can perform linear static earthquake analysis under the IS 1893 (Part 1): 2016 norm. While performing the earthquake analysis, various factors are involved such as timespan, scope of effect, territory component, and more.
To determine the cushioning impact of compressive pressures and the tightening impact of tensile loads, engineers use P-Delta analysis. It is a kind of secondary data analysis that helps to refine the structural design.
A building is meant to withstand various stresses and pressures including the force of a wind. Besides earthquakes, a structure must withstand wind depending on its location.
Note: ETABS was used to develop the mathematical model of the Burj Khalifa, designed by Skidmore.
A structural analysis describes the general shape and specific dimensions of a structure. With ETABS design software, the performance building analysis and design get refined as it offers both static and dynamic analysis for a wide range of gravity, thermal and lateral loads. In a concluding note, advanced software makes structural designing more beneficial in terms of sustainability and security.
