[h=2]They will remain structurally safe due to good construction, support from lift shafts: Experts[/h] Jose Hong



When an earthquake of magnitude 6.7 hit Sumatra at the weekend, Singaporeans living in residential areas such as Sengkang and Tanjong Rhu felt the earth move.
As objects in their homes shook and rattled, the thought in many residents' minds was: Can my Housing Board block withstand the tremors?
"Yes" was the response of experts interviewed by The Straits Times.


"The quake would have to be three to four times stronger to cause some light damage in Singapore," said Associate Professor Li Bing of Nanyang Technological University's (NTU) School of Civil and Environmental Engineering.
Even tremors from the strongest quake possible at the nearest fault zone to Singapore would not topple tall buildings here, like a 25-storey HDB block, the experts added.
Most likely, the building will experience low-level damage, but it would be structurally safe, said Assistant Professor David Lallemant of NTU's Earth Observatory of Singapore.



One reason is the lift shafts inside tall structures, he added. These shafts are built to support and prevent the buildings from swaying too much.
Prof Lallemant likened it to a shelf from furniture retailer Ikea: "The back part of the shelf - the metal 'x' - is what keeps it from swaying."
Another reason is that Singapore's buildings are well constructed, Prof Li said, adding: "Just as healthy people are less likely to get diseases."
In June 2000, Singapore was also shaken by tremors from an earthquake in Sumatra that measured 6.5 on the Richter scale.
They happened at around midnight and hundreds of residents from East Coast to Yio Chu Kang fled their homes as the series of strong tremors shook their beds and caused things to fall out of their cupboards.

Then Home Affairs Minister Wong Kan Seng emphasised that such natural occurrences were normal. Singaporeans should not be too worried or concerned, he said, adding: "If the earthquake is very severe, then Singaporeans will of course feel it in their homes".
Since then, the Government has also adopted a set of building codes that includes guidelines on making new buildings more resistant to earthquakes.
It was introduced in 2013 by regulator Building and Construction Authority (BCA). Older buildings that undergo major renovations will be brought up to the new standards.
Around the same time, a study concluded that it is unlikely for a quake to occur near and powerful enough to damage buildings in Singapore.
It was done by Professor Pan Tso-Chien of NTU's Institute of Catastrophe Risk Management.
The fault zone nearest to Singapore is the Sumatra fault and the strongest recorded earthquake it generated was of magnitude 7.7 in 1892.
In 1943, an earthquake struck at the point of the Sumatra fault that is closest to Singapore, around 400km away. The most powerful tremor it caused was of magnitude 7.6.
A BCA spokesman told The Straits Times that seismic waves from earthquakes along this fault zone closest to Singapore would arrive here at levels not significant enough to cause structural damage to buildings.
However, senior research fellow Aron Meltzner of NTU's Earth Observatory of Singapore urged caution. Although no similarly powerful tremors have occurred along the Sumatra fault since World War II, this does not mean it will not happen in the future, he said.
"Magnitude-7.7 earthquakes have happened in our historical past. We should plan for the likelihood of that within our lifetime," he added.





A version of this article appeared in the print edition of The Straits Times on August 16, 2017, with the headline 'S'pore buildings 'can withstand tremors from strongest quake''.

Re: Shit Times say Buildings can withstand strongest earthquake wor, u believe or not

.a study concluded that it is unlikely for a quake to occur near and powerful enough to damage buildings in Singapore .... no similarly powerful tremors have occurred....since WW II, this does not mean it will not happen in the future .....

Haha.....unlikely .....does not mean it will not happen.....good luck to those living in the older HDB blocks and the newer ones above 30 storeys .
Of course the rich living in landed properties or low rise need not worry so much but for the 70% living in the most expensive public housing in the world, good luck
Look at the train/lifts breakdowns, falling facades,U Changi Rd E viaduct collapse, hairline cracks in 26 MRT trains made in China(your HDB contractor form China?), SGH hepatitis gate-surely give you confidence?

Singapore is highly delusional.
This is like saying all the Paper Generals will win a war.

Our properties, including HDB flats, costs a lot of money to build. I am sure they are amongst the most stable and robust buildings anywhere in the world.

In that case, ask them to shake and scream under you. :biggrin:

No need earthquake. HDB will fall on its own.

Those old HDB blocks and for the same reason, many older condos build with actual brick are death traps in an earthquake. Brick construction has very little flex in an earthquake. Which means the building is not able to sway with the tremors and will go down. Even worse, pieces of it will fall off and kill people below. In earthquake zone areas of the world, you are not allowed to build houses with brick or tile roofs. Wood is the preferred medium of construction due to its ability to flex. For the shit times to come out and report this sort of shit is borderline criminally negligent.

The toughest construction standards regarding earthquake resistant buildings are in San Fran and Tokyo. We are not even 50% of their standard. Shit times talks shit.

even in kobe where reinforced concrete with high density of rebar designed to withstand level 6.9 failed any major infrastructure with massive concrete and high density rebar will fail depending on the waveform, depth, proximity and direction.

Same engineers who work on MRT also? LOL!

The steel in the structure of the buildings provides the flex. No?

The bomb shelter in HDB flats should hold right?

I can picture all these 10-20 storey high concrete columns standing tall after all around it has collapsed. Then people open the door and yell help help get me down. LOL!
