IS YOUR STEEL STRUCTURE READY FOR EARTHQUAKES?

IS YOUR STEEL STRUCTURE READY FOR EARTHQUAKES?

• 08/04/2025

🌍 Earthquakes strike without warning — but preparedness begins with smart design.
Amid increasing seismic activity and climate-related risks, designing earthquake-resistant steel structures is no longer an option, but a necessity. It ensures not only safety but also long-term operational stability.

At SEICO, we apply advanced seismic design principles to create steel buildings that are both structurally resilient and architecturally refined.

1. Choosing the Right Structural System

✅Steel frames combined with K-bracing or shear walls significantly improve lateral stiffness and control deformation under seismic loads.
✅For high-rise buildings, frame-wall hybrid systems offer an optimal balance between stiffness and ductility, ensuring better energy dissipation during earthquakes.

2. Smart Structural and Geometric Design

✅Avoid asymmetrical layouts or “soft stories” between floors, as they are vulnerable under seismic stress.
✅Short columns should be avoided due to their brittle failure modes.
✅Tightly connected structural elements help reduce relative displacement and enhance overall stability.

3. Enhancing Ductility for Energy Dissipation

✅Ductile detailing allows the structure to absorb seismic energy instead of collapsing.
✅Joints and connections should be designed for flexibility, and high-ductility steel should be used to maintain integrity under cyclic loads.

4. Designing Earthquake-Resistant Foundations

✅Select spread footings or pile foundations to better distribute seismic loads.
✅On weak soils, ground improvement techniques may be necessary to reduce risks such as liquefaction or differential settlement.

5. Dynamic Analysis According to Standards

✅Design must comply with TCVN 9386:2012 or international standards such as ASCE 7 or Eurocode 8.
✅Accurate dynamic analysis, including response spectrum evaluation and inter-story drift checks, ensures structural performance during seismic events.

6. Implementing Seismic Protection Technologies

✅Seismic technologies such as base isolators help decouple the structure from ground motion.
✅Energy dissipating devices (dampers) absorb seismic energy, reducing the force transferred to the structural frame.

DISCOVERING METHODS OF INSPECTING STRUCTURAL STEEL WELD JOINTS

• 14/03/2025

Welds are an important "bridge" in steel structures, ensuring a solid connection between components. However, during the welding process, welds cannot avoid defects, affecting the durability and safety of the project. Therefore, checking steel structure welds is extremely important, helping to detect errors early and have timely treatment measures.
