Report 221


An invited lecture is to be conducted by researchers, who are leading persons in the field of civil engineering in Vietnam, especially on steel structures. The main issue is to present the Vietnamese seismic-resistant design standards and the difference of structural design code and practices for steel structures between Japan and Vietnam. It was also planned to be a good opportunity to understand the actual condition of steel structures and disaster mitigation design in Vietnam.


The invited lecturers are Dr. TRAN Thu Tam and Dr. NGO-HUU Cuong who are researchers in Ho Chi Minh City University of Technology. The specialized field of Dr. TRAN Thu Tam is port and coastal engineering and the specialized field of Dr. NGO-HUU Cuong is structural engineering for buildings.
The main issue of the lecture is as below.
1) Features of Construction in Vietnam and Earthquake in Vietnam
2) Differences of design code and practices for steel structures between Japan and Vietnam

In Vietnam, there is no experience of seriously big earthquakes, but recently the frequency of small or middle earthquake becomes increase. Before 1975, there was no seismic design code in Vietnam. But after that, Russian seismic design code was adapted in Vietnam. And in the latter 2000s, American design code (AASHTO) and European design code (EUROCODE 8) were also applied to Vietnamese design code. These days, designers start to take earthquake into consideration for structural design.
However, seismic design is almost applied to a part of high-rise buildings invested by foreign capital. Seismic design is still unfamiliar to general engineers because they have not had enough knowledge and experience to seismic design. In Vietnam, it is expected that more and more experiences are accumulated.
They lectured about the differences of design code between Japan and Vietnam; Dr. TRAN Thu Tam lectured about pile design and Dr. NGO-HUU Cuong lectured about structural design for buildings. Basic design methodology is not so different, but details (ex. safety coefficients) are little different, and they pointed out that Japanese design code is more conservative in almost cases. And as mentioned above, the feature of Vietnamese design code is that several foreign design codes (Russian code, ASSHTO, and EUROCODE) are mixed.
After their lectures, lively question-and-answer was made, and we have deepened understanding to disaster mitigation design in Vietnam.
