Engineering - Civil (54)This project is utilizing an historic truss bridge to improve two courses in undergraduate civil engineering education, Structural Analysis and Construction Methods. The adaptive use of the truss bridge provides a vehicle for improving student's ability to create high quality computer models of structures and to develop high quality construction plans. Through this project, students are gaining a deep understanding of the differences that occur between real and theoretical structures in both analysis and construction. The project comprises four parts: (1) development of a protocol for adaptive use of historic truss bridges for pedestrian use, (2) development of a series of construction planning, sequencing, and estimating assignments that are based on the adaptive use of an historic truss bridge, (3) development of an instrumentation plan for the bridge, and (4) development of assignments for a structural analysis course that uses the measured deflections and forces in truss members and compares them to theoretical values. The project is being rigorously assessed to determine the impact on student learning and the materials developed are being widely disseminated for adoption at other institutions.

本项目利用一座历史悠久的桁架桥来改进土木工程本科教育中的两门课程：结构分析和施工方法。桁架桥的适应性使用为提高学生创建高质量计算机结构模型和制定高质量施工方案的能力提供了一种手段。通过这个项目，学生们对实际和理论结构在分析和构建方面的差异有了深入的了解。项目包括四个部分：(1)制定用于行人使用的历史桁架桥的适应性使用协议；(2)制定一系列基于历史桁架桥适应性使用的施工规划、排序和评估任务；(3)制定桥梁的仪器计划；(4)制定结构分析课程的任务，该课程使用测量的桁架构件的挠度和力，并将其与理论值进行比较。目前正在对该项目进行严格评估，以确定对学生学习的影响，所编制的材料正在广泛散发，供其他机构采用。
