Abstract

 Recently, opportunity of education is quite rare concerning theory of torsional warping at university or technical college. Engineer's general impression for the theory is so called very difficult. Therefore, a new educational program regarding the theory was developed in this study. The program is composed of a textbook and a lesson which adopts interactive learning method. Based on the beam theory lectured in elementary structural mechanics, the textbook has many figures to easily and visually grasp relation of bending and warping on beam with thin-walled polygonal cross section. According to results of questionnaire survey for subjects who experienced the program, it was revealed that good education effects and properly understandings are attained by the program.
