Thanks.EQ inherent forces supposed to create max moment at column beam connections.
Also shear failure should have happened at some height equivalent to width below that junction.
Such failures are difficult to be explained.

The slow motion video shows abrupt snapping of two columns as if it lacked ductility in reinforcement , acting as trigger for progressive collapse within seconds.
Lets discuss this in detail.

Probably the column for the first oscillation itself underwent the second order effect P-∆ & failed somewhere in the middle. It is a common type of failure of columns in soft stories.

Thanks to technocrats,
Nicely explain the earth quake happening
1. The lower part of the building, which is the elevated portion from the basement up to a certain height, plays a critical structural role.
2. The entire building behaves like a vertical cantilever under lateral loads such as wind or earthquake forces.
3. Maximum movements and stresses occur at the base or in the lower portion of the building.
4. This part of the building should be designed considering earthquake resistance and the oscillation behavior of the structure. Depends on Select of material, section required and its composite properly .
5. It is essential that this portion is ductile to effectively resist seismic forces from all directions.

Technical Brief; Preliminary Analysis of the Audit Office Building Collapse in Bangkok
Date: April 2025
Event: Collapse of 32-story Audit Office Building, Bangkok
Trigger: 7.7-magnitude Earthquake in Myanmar (March 28, 2025)
Status: Under Investigation 1. Background
On March 28, 2025, the 32-story Audit Office Building in Bangkok suffered a catastrophic collapse following seismic tremors from a magnitude 7.7 earthquake in Myanmar. Although the epicenter was over 500 km away, the seismic activity significantly affected Bangkok, exposing critical structural vulnerabilities. Initial observations and expert commentary provide insights into likely causes while a forensic investigation is ongoing. 2. Suspected Initiation Point
- Lower Column Failure: Failure likely began in longer columns on the lower floors, which are structurally more susceptible to buckling or shear under lateral load.
- Sudden Shear Failure: Eyewitness reports and video footage show rapid column shearing, suggesting brittle failure in vertical load-bearing members. 3. Likely Failure Mechanism
- Progressive Collapse: A cascading failure likely occurred after initial failure of critical components.
- Brittle Failure Mode: The sudden collapse without deformation indicates a brittle failure, potentially due to poor material quality or lack of seismic detailing. 4. Material and Design Concerns
a. Steel Quality Concerns
- Steel samples failed quality tests on mass, chemical composition, and tensile strength.
- Manufactured by a company with a record of safety violations.
- Substandard steel likely reduced the strength and ductility of concrete columns.
b. Structural System Vulnerabilities
- Flat Slab System: Lacks beams and is known to perform poorly in seismic zones.
- Construction Quality: Delays, worker shortages, and cost-cutting may have impacted structural integrity. 5. Role of Mechanical Couplers
- Couplers have not been confirmed as a contributing factor.
- Their role remains under review as part of the ongoing investigation. 6. Collapse of the Core Structure
- The core provided vertical and lateral support but relied on the surrounding structure.
- Once the lower columns failed, global stability was lost, leading to core collapse. 7. Summary of Key Findings (Preliminary)
Aspect
Findings
Failure Initiation
Likely in lower-floor columns due to longer span and weak material
Failure Type
Progressive and brittle collapse
Primary Suspect
Substandard steel—deficient in strength and composition
Design Concern
Flat slab system—vulnerable under seismic loading
Construction Issues
Alleged cost-cutting, worker shortage, and poor oversight
Core Collapse
Result of loss in global structural stability
Coupler Role
Not confirmed; under investigation
8. Recommendations for Further Review
- Conduct a comprehensive forensic analysis of material samples and structural debris.
- Implement a regulatory audit of steel supply chains and construction standard enforcement.
- Review seismic design of flat slab buildings in Bangkok and similar risk zones.
- Improve quality control, training, and site supervision for high-rise construction.9. Policy Recommendation:
Maintaining the highest quality standards is imperative at every stage of planning and executing large-scale structural or infrastructure projects. Achieving this requires the involvement of highly qualified experts and professionals throughout the design, construction, and supervision processes.
While post-incident investigations by leading experts are invaluable for diagnosing the causes of structural failures, they should not be the sole line of defense. Proactive policy reforms and administrative oversight must be institutionalized to strengthen quality assurance systems. We must insist and initiate wherever we find it absent.
Such measures are essential to prevent future failures and to ensure structural integrity and public safety from inception to completion.
Learning and learning appropriately from every event is very important for us, the active working professionals.

Dear Mahendra Barde,
Thank you for sharing this technical brief on the Audit Office Building collapsed in Bangkok. The preliminary analysis is informative and highlights several potential contributing factors.
While I appreciate the insights, I am concerned that the report seems to prematurely conclude regarding steel quality before the full forensic investigation is completed. I believe it's crucial to consider all aspects before drawing definitive conclusions.
I look forward to further updates as the investigation progresses.
Sincerely,

Dear Hemraj Chanchal,
Thank you for your thoughtful feedback on the technical brief regarding the Audit Office Building collapse. I appreciate your recognition of the preliminary analysis and your concern about the conclusions drawn regarding steel quality.
You are correct that the early findings should not overshadow the importance of a comprehensive forensic investigation. It is crucial that we consider all relevant factors to avoid premature conclusions.
As mentioned, the report was based on information from news media sources. Until a site visit, design details, and a thorough forensic analysis are conducted, we cannot reach conclusive technical findings. My conclusions focus more on policy and governance aspects.
I will ensure that all updates are provided as the investigation continues, and I welcome any further insights you might have.
Best regards,
Mahendra Barde .

[quote] Dear Mahendra Barde,
Thank you for sharing this technical brief on the Audit Office Building collapsed in Bangkok. The preliminary analysis is informative and highlights several potential contributing factors.
While I appreciate the insights, I am concerned that the report seems to prematurely conclude regarding steel quality before the full forensic investigation is completed. I believe it's crucial to consider all aspects before drawing definitive conclusions.
I look forward to further updates as the investigation progresses.

Dear Mahendra Barde,
Thank you for the clarification. I appreciate your commitment to a thorough investigation.
I understand that the initial report was based on preliminary information and that a comprehensive forensic analysis is necessary before reaching definitive conclusions. I look forward to receiving further updates as the investigation progresses and value your dedication to considering all relevant factors.
Thank you again for your time and consideration.
Best regards,

Thank you for your thoughtful feedback on the technical brief regarding the Audit Office Building collapse. I appreciate your recognition of the preliminary analysis and your concern about the conclusions drawn regarding steel quality.
You are correct that the early findings should not overshadow the importance of a comprehensive forensic investigation. It is crucial that we consider all relevant factors to avoid premature conclusions.
As mentioned, the report was based on information from news media sources. Until a site visit, design details, and a thorough forensic analysis are conducted, we cannot reach conclusive technical findings. My conclusions focus more on policy and governance aspects.
I will ensure that all updates are provided as the investigation continues, and I welcome any further insights you might have.
Best regards,
Mahendra Barde .
