Is your building earthquake safe? Probably not

Under construction buildings

Though earthquakes have wreaked havoc in many parts of the country, Indian real estate and infrastructure sector still has lots more to learn — and implement — to ensure the safety of life and property.

Although structural requirements and concerned technologies are incorporated in the building process, sector players say many modern technologies used worldwide are yet to be widely used in the country.

According to V.K. Gehlot, Director, National Centre for Seismology, “base isolation” and “dampers” are the major technologies to make buildings strong enough to resist seismic vibrations. But they are not widely used in India because of the cost involved and requirement of frequent maintenance.

Through base isolation, engineers decouple the building or the superstructure from its substructure which rests on ground, thus protecting the building during an earthquake.

Dampers on the other hand work as shock absorbers and minimise the magnitude of vibrations transmitted to the building from the ground.

The cost difference between a building with and without dampers is approximately Rs 350 per square feet, according to Major Sandeep Shah, Managing Director of Taylor Devices India.

The company is a manufacturer of earthquake-resistant equipment and he says “all developers” in the country are aware of the technology.

Shah said the company’s devices have been used in Terminal-2 of Chhatrapati Shivaji International Airport, Mumbai, lobby block building of Apollo Hospital, New Delhi, and New Udaan Bhavan at the Indira Gandhi International Airport, Delhi.

He pointed out that “at present none of the buyers are aware that by using dampers buildings can be protected and would remain habitable even after a major earthquake. That may be the reason why no one (buyer) is asking for such buildings.” But once they are made aware, Shah was sure they would want the technology in the building they are going to live in.

According to Aunirban Saha, Director (Marketing, Construction and Sustainability) of the Saha Groupe of Companies, “most of real estate projects are designed to the grade of ‘Earthquake Resistant — Collapse Prevention’ “. That means that in the event of a major earthquake, the building would not collapse and there won’t be any loss of life. However, the building itself would not be in a habitable condition and would need to be demolished and reconstructed, he explained.

The next higher standard is “Earthquake Resistant — Immediate Occupancy” in which the building may suffer some minor damage but there would not be any loss of life or property. “Rarely in the Indian real estate scenario buildings are designed to this category,” Saha added.

The highest category of structural safety is that of “Earthquake Resistant — Operational”. Under this, there would be no damage to the property or any injury caused to its occupants irrespective of the magnitude of the earthquake.

Saha said most developers go for the first category of “Collapse Prevention” as they find it more cost-effective. Most home buyers are not aware of earthquake-related safety grades, he added.

The higher structural grades, Saha said, made more sense in today’s market scenario for commercial real estate because such properties are preferred by big multinational companies.

According to Dikshu C. Kukreja, Principal Architect at C.P. Kukreja Associates, “all leading architects of India have the knowledge and skill about the technologies available to incorporate them in our designs and construction.”

Other than dampers, structural concepts such as bracing — where X-shaped braces strengthen the columns of the buildings — and couplers — where bars are joined together — help in absorbing movement during an earthquake.

Siesmologist Gehlot says that earthquake resistance should be enforced as a default, even for small structures. Today, when building a house, 95 per cent people do not bother about earthquakes. “Our usual way of construction is that we will give it to a mason and they will start constructing,” he adds.

All that needs to change, he emphasises.

The US presidential elections and future of India-US relations

Published

By

Donald Trump Joe Biden

As the coronavirus pandemic dominates global news in the United States, progress toward the next presidential election scheduled to be held on November 3 moves slowly forward. President Donald Trump had no real opposition in the Republican party and is running for re-election. And it has now become apparent that former Vice President Joe Biden will be his opponent as the Democratic candidate for president.

What would a Trump victory bode for the future of US-India relations? What would a Biden victory bode? Let me answer each of those questions in turn.

Given the love fests of Prime Minister Narendra Modi’s ‘Howdy Modi’ event in Houston, Texas, in which Trump participated in September of 2019, and Trump’s ‘Namaste Trump’ event hosted by Modi in India in February of this year, it might be assumed that the future for US-India relations is a splendid one. This would be an incorrect assumption.

Both of these events were more symbolic than substantive. Trump’s participation in them undoubtedly helped to persuade some — perhaps many — Indian American Modi supporters who voted for Hillary Clinton in 2016 to cast their ballots for Trump in 2020. Trump’s campaign team took steps to ensure this by holding an event at his Mar-a-Lago resort in which a group of prominent Indian Americans announced their plans to work for his re-election and to mobilize Indian Americans on his behalf.

To understand the future potential of India’s relations with the US. with Trump as president, however, it is necessary to look beyond these political moves and to examine the present state of those relations and Trump’s personal style.

In a word, the best way to characterize the current relations between the US and India is “functional”. The relationship was relatively good for the first two years of Trump’s presidency. In fact, near the end of 2018, Alice Wells, the Acting Assistant Secretary of State for South and Central Asia, was quoted in the media s saying: “This has been a landmark year for US-India ties as we build out stronger relationships across the board.”

Then, in 2019, the relations went off the track in the first half of the year after the US and India got into a tit-for-tat tariff war after the US terminated India’s Generalized System of Preferences which allowed India to send certain goods to the US duty-free. There have been continuing efforts to structure a “modest” trade deal since then. It was thought there might be some type of deal done in September of 2019 while Modi was in the US by year’s end, and then during Trump’s India visit. But, as of today, there is still no deal.

This inability to get any meaningful trade agreement in place speaks volumes about India’s potential future relations with India with Trump as president. So, too does Trump’s style.

Trump’s campaign slogans this time around are “Keep America Great” and “Promises Made, Promises Kept.” Trump is not a policy wonk and most of his effort will go toward “America First”. This involves making the US more isolated by withdrawing from international agreements, restructuring trade agreements, emphasizing building walls to stop immigrants at the border, using tariffs to block trade with countries who are taking away American jobs, and confronting businesses who are allegedlly stealing American trade secrets.

This perspective suggests what India can expect for its relations with the US if it has to deal with Trump for a second term as president. The relations will stay functional at best. As I have said before, that’s because the words partnership, cooperation and collaboration are not in Trump’s vocabulary. Nationalism, isolationism and protectionism are.

Joe Biden stands in stark contrast to President Trump both professionally and personally. Biden is a strategic thinker and doer with a solid eight-year track record of leadership experience as Vice-President in forging alliances that have made a difference around the world and he has also been a long-standing friend of India.

He was chairman of the Senate Foreign Relations Committee and a leading advocate for the Congressional passage of the Indo-US civic nuclear deal in 2005. At a dinner convened 10 years later in 2015 by the Confederation of Indian Industry and the Carnegie Endowment for International Peace, Vice President Biden discussed the tremendous joint progress that had been made by the two countries in the past and declared “We are on the cusp of a sea change decade.”

Early in his campaign for the Democratic nomination for president in July of 2019, in laying out his foreign policy vision, Biden stated that the US had to reach out to India and other Asian partners to strengthen ties with them. The items on Biden’s foreign policy agenda for strengthening which are of importance for India include climate change, nuclear proliferation and cyberwarfare.

During his vice presidency, Biden worked side by side with President Barack Obama to do things that would contribute to achieving Obama’s vision stated in 2010 of India and America being “indispensable partners in meeting the challenges of our time.” In 2020, those challenges are even greater than they were a decade ago.

That is why it is so essential that India and the US develop a strategic relationship that enables them to become those indispensable partners. That can happen if Biden assumes the presidency on January 20, 2021. It cannot happen if Donald Trump remains as president for a second term.

The results of this upcoming election in the US matter greatly for the future of the United States. They matter greatly for the future of India-US relations as well. Time and the American electorate will tell what that future will be.

45% of Indians do not back up their data, files: Survey

The survey was conducted among 728 Avast and AVG users between February 20-March 25.

New Delhi, March 30 : Nearly half of Indians do not back up because they think their data or files are not important enough and most of those who back up their data, do it once a month, a survey said on Monday.

Other reasons cited by the respondents for not backing up their data included not knowing how to do it, not having time and forgetting about it, according to the survey by cybersecurity company Avast.

“It could be that many aren’t aware they are backing up, as it could be happening automatically, in the background, however, others really might not be backing up at all, thinking it is not worth it,” Luis Corrons, Security Evangelist at Avast, said in a statement.

“Losing personal documents, photos and videos can be a painful experience and it’s not until this happens that they realize how valuable it actually is,” Corrons added.

Of those who do back up their data, nearly 42 per cent Indians back up to a cloud storage, 36 42 per cent back up their data to an external hard drive, 23 42 per cent back up to a USB or flash disk, 18 42 per cent back up their phone to their PC, and 10 42 per cent back up to a network storage drive, the results showed.

Corrons recommended to back up data to two different locations, like the cloud, and a physical storage, like an external hard drive.

When it comes to iPhone and Android phone owners, the percentage that backs up is nearly the same, 69 per cent and 70 per cent respectively.

The percentage of smartphone owners that don’t know how to back up their data does not vary much between iPhone and Android owners, with 13 per cent and 17 per cent claiming not knowing how to, respectively, the study revealed.

Data loss can be caused by users accidentally deleting their data themselves, hardware damage and failure, as well as malware, causing valuable data such as photos, videos, documents, and messages to be lost forever.

Ransomware and other malware, such as wipers, can either encrypt or completely destroy files, and there is no guarantee that files can be decrypted if a ransom is paid.

The survey was conducted among 728 Avast and AVG users between February 20-March 25.
