According to Government sources, two steel samples collected from a building collapsed under construction in Bangkok have been inferior. The 33 -story structure was collapsed on March 28 after a magnitude of 7.7 earthquake caused significant damage to Myanmar and Thailand, killing 18 people.
The collapse of the building has resulted in a furious controversy, as no other high structures in Bangkok, which is 1,000 km from the Epicenter of Earthquakes in Myanmar, has been severely affected. More than 2,000 people have died in Myanmar as a result of the earthquake so far. The Red Cross also stated that some of Myanmar’s prey could have been damaged, but there are no confirmed reports on breaches.
The non -profit iron and steel institute is examining seven samples of 32 mm, 25 mm, 20 mm, 16 mm and 12 mm deformed steel bars, wire ropes and collected steel bars From the wreck by an official team led by the Minister of Industry, Akanat Promphan.
Thitipas ChotedeChachainan, head of the Technical Research Team, said that the 32 mm deformed steel bars did not comply with the strength receipt value, while the 20 mm bars did not comply with the mass-m standard.

The government of Thailand has ordered an investigation into the design and structural integrity of the building built by China’s 10 engineering group, a Chinese government entity. The project, commissioned by the State Audit Office, is jointly owned by this company and Italian developing PLC.
The controversy of the Bangkok building took a dramatic turn when police detained four Chinese citizens attempted to steal 32 documents from the waste after the earthquake, according to Nopasin poolswat, an assistant commissioner of the Metropolitan Police Office. The arrested individuals said they were trying to recover documents to make an insurance claim.
Amorn Pimarnmas, President of the Structural Engineers Association of Thailand, said that Bangkok’s soft floor could also have participated in the collapse of the building, as it can amplify the earth’s movements three or four times.
“However, there are other assumptions such as [concrete and reinforcement] quality and certain irregularity in [the] Structural system. It remains in detail, “he said.
Authorities will also examine the construction method in the project of $ 58 million and made efforts to make it resistant to the earthquake.
Christian Málaga-Chuquitaype, Principal in Earthquake Engineering at the Imperial College London, who saw a video of the collapse and the wreck, said that it seems that a process of building flat slabs is being used, which is no longer recommended in areas prone to the earthquake. “A flat slabs system is a way to build buildings where soils are made to rest directly on columns, without using beams,” he told the BBC.
“Imagine -you are a table supported only by the legs, without additional horizontal supports below … Although this design has architectural costs and benefits, it works badly during earthquakes, often failing in a brittle and sudden, almost explosive way,” he added.
The collapse raised questions about the quality of government supervision for construction projects.
Mana Nimitmongkol, President of the Thailand Anti-Corruption Organization, said that the State Audit Office, which commissioned the project, was preparing to cancel it last January due to the intermittent work stops of the contractor in the early stages followed by significant delays.
