Please help me find an example of building collapse due to structural problems.

I remember watching an analysis of the collapse of a building in Singapore on TV.

I searched the following. Yes 197 1 Singapore New World Hotel collapsed instantly.

However, one Saturday morning, a sudden disaster hindered the operation of the whole area. A six-story hotel completely collapsed in less than 60 seconds. The disaster killed 33 people, and 17 people were buried alive under thousands of tons of steel bars, concrete and glass slag. This is the worst crash in Singapore's history, and it is also the most puzzling event for investigators. Now, advanced computer technology will help us accurately reveal the cause of this tragedy. Disaster does not happen for no reason, it is composed of a series of decisive events over a period of time. "Only a few seconds from disaster" will reveal the truth of the fatal moment for you.

This country, the size of new york, has a population of more than 3 million. In the center of the city, tall buildings soar into the sky. This is a masterpiece created by architects who strive to use limited space. After all, a lot of land here comes from reclamation and swamp reclamation. On Owen Road, there is a New World Hotel built at 197 1. This building is very ordinary: 36 reinforced concrete columns support a six-story concrete structure.

In the horrible 1 minute, the whole New World Hotel collapsed and thousands of tons of reinforced concrete rained down on people. This building, once regarded as a local landmark, has only a lot of rubble left. You can see smoke everywhere for miles. The six-story building was instantly destroyed and turned into a cement grave.

In a city like Singapore, this disaster has become everyone's nightmare. Similar buildings can be seen everywhere in the local area, and there are many higher buildings on the island. To this end, investigators must find out the cause of the collapse of the New World Hotel as soon as possible.

How did a six-story reinforced concrete building collapse in 60 seconds?

After a long period of investigation, it is certain that the collapse of New World Hotel was not due to explosion or poor construction quality. Isn't it because of the swamp? Or a subway tunnel.

By reviewing what happened on the day of the disaster and conducting in-depth investigation afterwards, we can finally reveal the real reason for the collapse of the New World Hotel. A fatal mistake kept the building on the brink of disaster for 15 years after its completion. The draftsman only considered "live load", but forgot "fixed load". This is a shocking discovery and a low-level mistake. The draftsman's calculation was so wrong that such important columns as No.26 and No.32 could not bear the weight of the building. Even without those extra "active loads", such as air conditioning equipment, durable glazed tiles and bank vaults? Since 15, many columns supporting the building have reached the edge of the support limit. Almost all the columns have been destroyed long ago and supported on the edge of collapse 15 years.

This tragedy has taught people a lesson. Singapore has completely revised the rules and regulations of construction projects to ensure that all "fixed loads" and "live loads" calculated by architects must be independently audited. Many other countries in the world have also adopted this important additional security measure. Like many cities, buildings in Singapore are still being built higher and higher. Fortunately, whether in Singapore or other countries, there are fewer and fewer cases of building collapse. However, when disasters happen, the noble character and courage displayed by ordinary people are still amazing.
