Experimental cracking-twist data on torsional concrete beams display significant variations due to the difficulty of measuring small twists during torsion tests of concrete beams. A recent torsion experiment on large reinforced concrete (RC) beam specimens developed a new method that was able to accurately measure small twists before and around cracking. In the current study, the test method was extended to torsion experiments on prestressed concrete (PSC) beam specimens. In addition to addressing the issue of small-twist measurement, the new method also improved other aspects, such as precise measurement and examination of prestressing forces and prestress transfer, and the testing of relatively large specimens with medium to high prestressing levels. This paper describes the test apparatus and method, presents the experimental results of six PSC beam specimens, and discusses and compares the experimental results.

National Chi Nan University of Introduction:

In 1995, National Chi Nan University (NCNU) was founded in Puli, Nantou County, in central Taiwan. Today, it has a student population of over 6000, and a faculty and staff strength of 550. NCNU aims to distinguish itself through the following four  vision statements: “Infuse local distinctive features”, “Integrate humanities and technology”, “Aggregate traditional and foreign education” and “Combine ecology and environment protection”.

The Name "Chi Nan" conveys the school's mission: to spread Chinese culture and learning from North to South, from China to the overseas world. "Chi Nan" was first used as the title of an academic organization more than a century ago. "Chi Nan Academy," establised at the end of Ch'ing Dynasty, and "Chi Nan University, " established in ShangHai after the founding of the Republic, were both deciated to educating and teaching talented Chinese Youths born or raised abroad. The choice of the name "Chi Nan" therefore also conveys our intention of take up this mission and to devote ourselves to the education of talented youths from both within and outside of China.

Under the current development trends of the global economy, Southeast Asia is rising economically as global factories move southward; thus, this region has become a major market for Taiwan’s international trade expansion. Through our continual effort in developing higher education for overseas Chinese students, and our research in Southeast Asian education, NCNU enjoys an advantage in the Southeast Asian higher-education market. NCNU houses the best Southeast Asia Research Institute and Southeast Asia Research Center in Taiwan; we also have the largest enrollment of students from Southeast Asia. NCNU will soon establish a university-wide specialized curriculum on Southeast Asia. While we cultivate in NCNU graduates an international perspective, we particularly inculcate in them an emphasis on Southeast Asia so as to enhance their competitiveness for international employment.
NCNU currently have College of Humanities, College of Management, College of Science and Technology, College of Education, and General Education Center; there are total of 18 bachelor degree programs, 24 mater degree programs and 14 PhD degree programs.
