华人网络与韩人网络的比较研究

通过当前韩国对于海外华人四个方面的"似是而非"认识的分析,对华商网络的倾向与特征、建设韩民族网络等问题的探讨,得出结论:韩国华侨与韩国所理解的海外华人之间存在很大的差异;当代韩国政府希望能像中国充分发挥海外华人的优势那样,使海外韩人发展成为韩国在21世纪的新的成长动力并加以利用的认识是一种错误的"乐观判断";海外华人对祖国的向心力,不只是来自爱国情,更重要的是其生存保障与利益的实现;中韩两国的侨务政策存在区别,中国致力于"护侨",而韩国的目光集中于"用侨"。     

EVALUATION OF DEFORMATION CAPACITY FOR RC T-SHAPED CANTILEVER WALLS

If RC structural walls are properly designed and proportioned, these walls can behave in a ductile manner. To achieve this goal, the designer should provide adequate strength and deformation capacity of structural walls corresponding to each performance level (e.g. immediate occupancy, life safety and collapse prevention). This study investigates the drift and ductility capacities of T-shaped structural walls on the basis of results from experimental tests and sectional analyses. To determine proper deformation capacities for T-shaped structural walls, structural performances of T-shaped walls were evaluated with several parameters such as longitudinal reinforcement ratio, distribution of longi-tudinal reinforcement, lateral confinement ratio, and axial load ratio. Based on these results, the level of deformation capacity specified in current design provisions (ICBO, UBC 1997), which were expressed as both strain-based damage limit and interstorey drift ratio, were evaluated.
