The Ministry of the Interior yesterday outlined recent changes to building codes that include new mandates to reinforce structures susceptible to earthquakes.
The amendments to the Building Earthquake Resistance Design Regulations and Explanation (建築物耐震設計規範及解說) went into effect on Oct. 1.
Many tall buildings in Taiwan have been improperly modified to house street-level shop fronts, which can compromise structural integrity during a quake, National Center for Research on Earthquake Engineering Director-General Chou Chung-che (周中哲) told a news conference.

Illegal constructions on top of buildings are another vulnerability common in buildings throughout the nation, he said.
The new rules require susceptible buildings to install ad hoc structural reinforcements to boost safety until a long-term solution can be implemented, be it an overhaul or demolition, Chou said.
The ministry and the center have ensured that every vulnerable student dormitory up to the junior-high school level has been reinforced, he said, adding that they are now focusing on hotels, markets and other public buildings.
People who are concerned about the structural integrity of the building they live in can contact the center for help, especially for structures that have exposed pillars, he said.
The new rules revised quake resistance standards for structures near fault lines to include the ability to withstand shallow earthquakes, he added.
This means new buildings near fault lines must be 20 to 30 percent more resistant to quakes than before, which translates into an estimated 5 percent increase in construction costs, Chou said.
The center is collating information on land liquefaction cases to map risks nationwide while fine-tuning testing protocols and quality-control procedures for base isolation and quake reduction components, he said.
People are encouraged to use government subsidies to check the quake resistance of their residential buildings, Construction and Planning Agency Director-General Wu Hsin-hsiu (吳欣修) said.
“The safety of your house is far more important than its real-estate value,” he said.
Taiwanese scientists have engineered plants that can capture about 50 percent more carbon dioxide and produce more than twice as many seeds as unmodified plants, a breakthrough they hope could one day help mitigate global warming and grow more food staples such as rice. If applied to major food crops, the new system could cut carbon emissions and raise yields “without additional equipment or labor costs,” Academia Sinica researcher and lead author the study Lu Kuan-jen (呂冠箴) said. Academia Sinica president James Liao (廖俊智) said that as humans emit 9.6 billion tonnes of carbon dioxide compared with the 220 billion tonnes absorbed
The Taipei Mass Rapid Transit (MRT) Wanda-Zhonghe Line is 81.7 percent complete, with public opening targeted for the end of 2027, New Taipei City Mayor Hou You-yi (侯友宜) said today. Surrounding roads are to be open to the public by the end of next year, Hou said during an inspection of construction progress. The 9.5km line, featuring nine underground stations and one depot, is expected to connect Chiang Kai-shek Memorial Hall Station to Chukuang Station in New Taipei City’s Jhonghe District (中和). All 18 tunnels for the line are complete, while the main structures of the stations and depot are mostly finished, he
Taipei is to implement widespread road closures around Taipei 101 on Friday to make way for large crowds during the Double Ten National Day celebration, the Taipei Department of Transportation said. A four-minute fireworks display is to be launched from the skyscraper, along with a performance by 500 drones flying in formation above the nearby Nanshan A21 site, starting at 10pm. Vehicle restrictions would occur in phases, they said. From 5pm to 9pm, inner lanes of Songshou Road between Taipei City Hall and Taipei 101 are to be closed, with only the outer lanes remaining open. Between 9pm and 9:40pm, the section is
China’s plan to deploy a new hypersonic ballistic missile at a Chinese People’s Liberation Army Rocket Force (PLARF) base near Taiwan likely targets US airbases and ships in the western Pacific, but it would also present new threats to Taiwan, defense experts said. The New York Times — citing a US Department of Defense report from last year on China’s military power — on Monday reported in an article titled “The missiles threatening Taiwan” that China has stockpiled 3,500 missiles, 1.5 times more than four years earlier. Although it is unclear how many of those missiles were targeting Taiwan, the newspaper reported
