When a building collapses, the first failure is rarely the last.

Progressive collapse begins with a local structural failure.
A column. A beam. A connection.

The real question is not why the first element failed.
The real question is what happens next.

Can the structure redistribute the load?
Or does the failure spread from floor to floor?

As structural engineers, our responsibility is not only to design for normal loads.
It is to ensure that local damage does not turn into disproportionate collapse.

What is seismic isolation?

Seismic isolation is a smart structural solution that reduces earthquake forces before they reach the building.

By separating the structure from ground motion, we can significantly reduce acceleration, base shear, and structural damage.

This system is widely used in hospitals, data centers, and critical facilities where performance and safety matter most.

Structural engineering is not only about strength. It is about smart design.

What Is an Outrigger System?

The outrigger system is one of the most effective solutions for controlling lateral behavior in tall buildings.

Used in many iconic skyscrapers, it transforms the entire structure into a much stiffer system under wind and seismic loads.

How to Export ETABS Loads to SAFE

In this video, ETABS loads are imported into SAFE, where transferred forces can be reviewed and verified at joint locations.

ETABS Tip: Editing Grid Lines After Modeling

Grid changes can easily break your ETABS model if they are not handled correctly.

When you modify grid lines without enabling Glue Joints to Grids, the grids move but the structural elements stay behind. This leads to misaligned columns and beams.

The correct workflow is simple: Before modifying grid systems, always enable Glue Joints to Grids.

It keeps your entire model aligned and safe.

8 Common Lateral Load Resisting Systems in Buildings

Learn ETABS & SAFE by Designing a Real Building: Tall Building Design in ETABS + Foundation Design in SAFE

If you want to design real buildings, you need a clear, step by step workflow.
That’s why we created two complete project based courses: one for designing high rise buildings in ETABS, and one for designing reinforced concrete foundations in SAFE.

Both courses teach you the full process: modeling, analyzing, designing, detailing, and coordinating everything just like a real engineering project.
Whether you’re a student, a new engineer, or already working in the field, these lessons help you.

Structures experience many different forces, and each load affects how we design for safety and performance.

This post breaks down the key loads every engineer considers:
• Dead Load
• Live Load
• Wind Load
• Seismic Load
• Snow Load
• Temperature Load

How to Model A Complex Curved Building in ETABS (Part 2)

Continuing from the previous part, now we’re modeling the floor slabs for this curved twin-tower building in ETABS.

We’ll use Quick Draw Floor, Draw Rectangular Floor, and Draw Floor tools to create both regular and irregular slab areas.

Watch till the end to see how the edge slabs and boundary beams are modeled!

ETABS Tutorial: Center of Mass & Center of Rigidity

Finding the Center of Mass (CM) and Center of Rigidity (CR) is one of the key steps in understanding a building’s seismic behavior.

In ETABS, these two points help us evaluate plan irregularity, torsional effects, and distribution of stiffness and mass across the structure.

In this short tutorial, we’ll walk you through how to locate them step by step: selecting the slabs, assigning a rigid diaphragm, enabling the CM and CR calculation, running the analysis, and finally viewing the results in the “Centers of Mass and Rigidity” table.

Understanding the offset between CM and CR is essential for identifying torsional eccentricity and ensuring a more reliable seismic design.
