Terrible reasons for the collapse of New World Hotel Building in Singapore

yewb 2065438

On Owen Road in Singapore, there is a New World Hotel, which is built in 197 1 and has a six-story reinforced concrete frame structure. On March 1986, the whole New World Hotel collapsed in a horrible 60 seconds. * * * 33 people died.

The root cause of the collapse: it is the low-level mistake of the cartographer. In the structural calculation of the 36 load-bearing columns of the design building, only the "live load" (that is, the living articles such as furniture and central air conditioning brought by people after the building is completed, and the actual live load is about100t when it collapses) is considered, while the "fixed load" (that is, the dead load, that is, the weight of the building itself, that is, 6000t) is forgotten. That is, the load-bearing design of these 36 load-bearing columns ignores the weight of the building itself;

Process reasons (many errors can be found and avoided in all links of the process):

1, designer; (Starting point of this error)

2. Design review;

3, the government's review of design drawings;

4, the construction unit audit;

5. Acceptance of the construction unit itself;

6, the development unit self acceptance audit;

7. Post-construction audit of the government;

8./kloc-maintenance audit during 0/5 years;

9. Residents and property management personnel found cracks in the load-bearing columns, which were not reported, but only painted and decorated;

In the national geographic channel program, only the above-mentioned 1 and 9 points were mentioned;

People always ignore the audit work and go through the motions.

The most important thing in quality management (such as ISO 9000 series) is process management, and the key to process management is the audit of each link.
