Undergraduate education in Structural Engineering lacks sufficient integration of full-scale testing into structural design courses. This is true of all undergraduate programs we investigated; students experiment with structural materials, but not with structural components. many state of the art design procedures for structures in steel, reinforced concrete, masonry, and wood are based on specific aspects of behavior that would be simple to illustrate in a properly equipped lab, but which are otherwise never seen by the students. Allowing the students to plan and conduct tests which demonstrate the behavior of structural components to failure will have a direct impact on their ability to understand the specific concepts illustrated in the tests - and also on their motivation to learn related concepts. We believe that the reason this is not done is that no university has appropriate equipment devoted to such use in undergraduate programs. The equipment described in this proposal will be used to conduct tests of full-scale structural components in advanced undergraduate structural design classes. The tests will illustrate the most critical concepts affecting design procedures. Specimens will be constructed by students in a sophomore level lab class, giving these students a real object to construct and also providing continuity between the years of study. The equipment will also be used by Construction Management students to evaluate construction processes.

结构工程本科教育缺乏将全尺寸测试充分融入结构设计课程。我们调查的所有本科项目都是如此；学生们用结构材料做实验，而不是用结构部件。许多最先进的钢、钢筋混凝土、砖石和木材结构的设计程序都是基于特定的行为方面，这些方面在设备齐全的实验室中很容易说明，但学生们却从未见过。允许学生计划并进行测试，以证明结构部件在失效时的行为，这将直接影响他们理解测试中说明的具体概念的能力，也会影响他们学习相关概念的动机。我们认为，之所以没有这样做，是因为没有一所大学有适当的设备专门用于本科课程。本建议书中所述的设备将用于在高级本科结构设计课程中进行全尺寸结构部件的测试。这些测试将说明影响设计过程的最关键的概念。标本将由学生在二年级的实验课上构建，给这些学生一个真实的对象来构建，也提供了学习年份之间的连续性。这些设备也将被建筑管理专业的学生用来评估施工过程。
