Abstract

A landmark full-scale test of a five-story reinforced concrete building was conducted on the NEES@UCSD shake table. The building was completely furnished with nonstructural components and systems. The knowledge gained from extensive data and video collected during construction, fabrication and installation phases of this project provided a unique opportunity to develop visual resources to enhance education. To this end, educational videos were produced to promote learning in courses such as reinforced concrete, foundation design, and/or construction management. Three videos describing the overview of construction, foundation specific construction, and moment-frame construction, and two videos describing the installation of nonstructural components such as the egress system (stairs and elevators) and facades were created. The videos highlight the process of forming concrete, placing rebar, and pouring columns, walls, slabs and beams. They also emphasize material tests and important characteristics of reinforcing steel and poured-in-place concrete. The videos were shown in several undergraduate structural engineering courses at UCSD and were also presented in a high school summer engineering camp. Surveys from these courses indicated that the facts and knowledge gained by the students were aligned with the educational objectives of the videos. Feedback also focused on the quality of the video and how to improve the delivery. Overall, the assessments were favorable and highlight the effectiveness of bringing large-scale experimentation through the use of video modules into the classroom to increase the understanding of practical construction and engineering techniques.

Introduction

Educational modules using extensive data and video from a landmark full-scale test conducted on the shake table at UC San Diego were developed. The emphasis of the learning modules was to visually describe the process of construction, fabrication and installation of structural and nonstructural components and systems. They are intended to supplement curriculum and enhance student learning in courses such as reinforced concrete, foundation design and/or construction management. Examples of the structural modules include videos documenting the process of forming for concrete construction, placing rebar, and pouring columns, walls, slabs and beams. Nonstructural examples include installation of in ceiling systems, passenger elevators, stairs, architectural façades, and fire protection systems. All of these processes (fabrication, construction, installation, instrumentation, and testing) were extremely well documented in the project, providing a unique opportunity to utilize the vast data gained from the construction, fabrication and installation phases of the project to enhance education. 

Earthquake Engineering Component

Three structural videos describing the overview of construction, foundation specific construction, and moment frame construction were developed and are described in detail in this paper. Three additional nonstructural videos highlighting the installation of the egress system (stairs/elevator), the façade (balloon framing/precast concrete cladding), and the medical floors are also in preparation to complement the structural series. The modules, intended for undergraduates, are broadly applicable to graduate and high school students. The main objectives for developing these educational tools are to provide an effective learning experience for students to gain deeper knowledge in the practical aspects of building design and construction.
