Pinoy invents device that measures building’s structural integrity

MANILA, Philippines – The stability of a structure is best tested during strong earthquakes.

However, inspections usually take days to determine if a building has damage or if it can be declared safe to use.

To help in the process, a Filipino inventor has created a device which can be installed to a structure to measure its strength.

It is called the universal structural health evaluation and recording system (USHER).

Universal structural health evaluation and recording system (USHER).

Dr. Francis Aldrine-Uy said with the device, a building’s structural condition can be assessed just a few hours after an earthquake.

The local government units (LGUs), meanwhile, can immediately direct orders even to the most affected areas right after the device’s assessment is seen.

“Makikita na natin kung nakapula yung mga building na iyon, ibig sabihin nag-suffer ng structural damage ang mga building na iyon after an earthquake (We can see if the buildings are in color red, it means that the building suffered structural damage after the earthquake,)” explained Dr. Uy, the President and CEO of USHER, the inventor of the device.

“Doon po natin i-concentrate ang tulong o ang response na pwede nating madala doon, (That’s where we may concentrate our response,)” he added.

The invention, which is in cooperation with the Department of Science and Technology (DOST), can be installed in public facilities like bridges and railways of MRT and LRT.

The device can also measure the degree of intensity when an earthquake strikes.

Regarding the price, Uy said it is way cheaper than those made abroad.

“It could be at least 50% lower in cost,” Dr. Uy said.

“And of course, it will be more sustainable dahil nga ito ay gawang Pinoy at dito natin mina-manufacture (because it’s Filipino made and is locally manufactured),” he added.

Dr. Uy said the instrument can help in mitigating the impact of a strong quake like ‘the Big One’ which is expected to cause massive damages and loss of thousands of lives. – MNP (with reports from Rey Pelayo)

The spirit of bayanihan has proven itself timeless.

In the digital age, a group of photographers has gathered together to launch ‘Bayanihan para sa Batanes’.

READ: Congressmen to donate part of their salaries for Batanes quake victims

In their Facebook page, they put up their works for sale. All the proceeds will go to the victims of the Itbayat earthquake. 

Like a digital art gallery, the Facebook page of Bayanihan para sa Batanes is filled with moments — moments of nature, of people captured in the eyes of various photographers.

According to one of the photographers, RA Valderama, it all started with a group of friends who dearly love Batanes.

“It started by just selling a few photos, and calling attention of other photographers who want to help as well in this advocacy” he said.

Bayanihan has also proven itself limitless, it is not just about neighbors helping neighbors. According to Valderama, more than a dozen photographers across the country have submitted their works for the campaign.

“Before we know it we are almost 50 in number,” he said.

The spirit of bayanihan today goes beyond the willingness to share your physical strength. For these photographers as long as they can, they will.

Valderama said they are still open for more photographers.

“We still accept photographers who want to share their art and help this cause,” he said.—AAC
