SThe Association of Structural Engineers of Thailand reveals 3 causes of the Hua Mak Stadium indoor roof truss collapse.
4 Oct. 2023, from the collapse of the roof structure of the Hua Mak indoor stadium building on 3 Oct. 2023, the Association of Structural Engineers of Thailand, led by Prof. Dr. Amorn Pimanmat President of the Association, Mr. Chulert Jitjuajun, Vice President of the Association, and Mr. Watthanaphong Hirunman, Secretary-General of the Association. Inspected the area To analyze the causes together with Engineer of the Sports Authority of Thailand
From the initial evaluation and analysis of the cause and sending a drone to inspect the condition of the top of the roof frame, it was found that the steel frame supporting the drainage gutter had collapsed in two lines at a high height. From the initial inspection of the structural system, it was found that The end of the wire rope slips from the anchor point. Let the steel beam lose its support. So it collapsed. and were able to analyze three factors that caused the collapse:
1. Heavy rain has water on the canvas. cause a lot of weight And some of the water was too heavy for the canvas to bear. causing the waterfall to hit the gutter and caused the wire rope supporting the steel frame to break from the support point.
2. A structural system that uses wire ropes stretched at the support points. through the iron wedge When the iron ingot rusts Make the wire rope come out. Until he lost the strength to support his weight and fell.
3. Structures that have been built for 50 years or more have deteriorated, such as rotted wooden frames or rusted angle iron frames. making it unable to bear weight
From the condition of the building’s structure which is round and like a dome. It has a very long range. And the canvas above is still torn in many places. There are also many similar characteristics. There may be additional landslides in other locations. Especially in the rainy season when there are strong windstorms during this period. Therefore, initially Therefore, it should be closed for use inside this building. and should hurry to evaluate and repair the roof structure first which initially expected It will be used to survey and evaluate the structure within approximately 2–3 months, after which it will be repaired. and strengthen the roof frame This will take another 3-6 months depending on the severity of the damage.
