9451838 Makris Instructive experiments in Structural Engineering are to be conducted by undergraduate students in the Department of Civil Engineering and Geological Sciences. The scope of this project is the development of laboratory course in experimental structural engineering in order to expose students to modern methods. Too large-scale experiments will be conducted. The first experiment is associated with the Reinforced Concrete Design course and is the study of the behavior of a reinforced concrete column under static and cyclic loading. Students will measure quantities of significant importance in structural analysis and design, such as initial stiffness, yield point, ultimate strength, dissipated energy, member ductility and stiffness deterioration. The second experiment is associated with the Reduction of Natural Hazards course and is the study of determination of damping of a structural component. Students will conduct oscillatory tests at different frequencies to extract the dynamic mechanical characteristics of structural component. A capstone project will complete the course. The objectives in offering the course are twofold: a) to increase the physical understanding of students, about structural behavior, in a systematic and comprehensive way that will support and clarify their theoretical knowledge, and b) to familiarize them with current experimental techniques used in the state-of-the-art industrial and academic laboratories.

9451838 Makris结构工程指导性实验将由土木工程与地质科学系本科生进行。这个项目的范围是开发实验结构工程的实验课，以使学生接触到现代方法。会进行太大规模的实验。第一个实验与钢筋混凝土设计课程有关，是研究钢筋混凝土柱在静力和循环荷载作用下的性能。学生将测量结构分析和设计中重要的数量，如初始刚度、屈服点、极限强度、耗散能量、构件延性和刚度劣化。第二个实验与减少自然灾害有关，是关于确定结构部件的阻尼值的研究。学生将在不同的频率下进行振动测试，以提取结构部件的动态力学特征。顶石项目将完成这门课程。开设这门课程的目的有两个：a)以系统和全面的方式增加学生对结构行为的物理理解，以支持和澄清他们的理论知识；b)使他们熟悉最先进的工业和学术实验室中使用的当前实验技术。
