Myoung1� 1 Dept. of Materials Science and Engineering, Yonsei University 134 Shinchon-dong, Seoul 120-749, Republic of Korea 2 Dept. of Civil and Environmental Engineering, Yonsei University 134 Shinchon-dong, Seoul 120-749, Republic of Korea Keywords: ZnO; Nanowire; AFM Probe; Nanomechanics Abstract.
Unlike macro-scale engineering structures, large elastic deformation reaching several tens of percent strain is possible with nanostructures, if the nanowires contain very low amount of structural defects, resulting in non-linear load-deformation behaviour such as that shown in Fig. 3 [3].

Introduction Steel structure construction is an important course of the civil engineering major, how to improve the students’ skill of steel structure construction in school is an important work which we had discussed always.
Based on the idea of learning by simulation operating, the virtual simulation teaching system of steel structure construction, with the background of a certain typical steel structure factory’s installation, includes 9 simulation tasks (Checking bolts of foundation, steel columns installation, tied and scissors installation between columns, purlins installation etc.) which were designed according to the working process and 9 function modules (engineering drawings, construction codes, construction technical clarification, construction safety clarification etc.) which were used for each task, and includes rules’ explanation of steel structure construction code, judgment systems of students’ operations (Fig. 2).
