从1996年到今天,整整十年时间,上海大学土木工程系从办大土木的视角出发,立足上海、服务全国,主动适应国家经济社会日益发展对土木工程人才的需求。在土木工程系的本科教育中,我们率先在国内探索并开展了“土木工程概论”课程的创立与建设工作。在课程建设初期,我们就在定位上瞄准了争创国内一流的目标;在内涵上实现教学规律和工程规律的结合;在模式上立足于立体化的全程建设;在理念上把握把教的创造性留给老师,把学的主动权还给学生。十年来,我们围绕课程建设,在师资队伍、课程、资源、教学改革、科学研究以及教学形式、方法、手段、情景设…  相似文献   

Some Problems in Nonlinear Dynamic Instability and Bifurcation Theory for Engineering Structures     

彭妙娟  程玉民 《上海大学学报(英文版)》2005,9(1):29-34

In civil engineering, the nonlinear dynamic instability of structures occurs at a bifurcation point or a limit point. The instability at a bifurcation point can be analyzed with the theory of nonlinear dynamics, and that at a limit point can be discussed with the theory of elastoplasticity. In this paper, the nonlinear dynamic instability of structures was treated with mathematical and mechanical theories. The research methods for the problems of structural nonlinear dynamic stability were discussed first, and then the criterion of stability or instability of structures, the method to obtain the bifurcation point and the limit point, and the formulae of the directions of the branch solutions at a bifurcation point were elucidated. These methods can be applied to the problems of nonlinear dynamic instability of structures such as reticulated shells, space grid structures, and so on.  相似文献
