| The information and data related to the large-scale structural experiments are often complicated and contained in various documents, drawings, photos, and other computer-based files. A data model is needed to efficiently access, share, and use the information and data. The Lehigh Model was developed by Lee et al. (2006) at the Real-Time Multi-Directional (RTMD) earthquake simulation facility at the ATLSS Center at Lehigh University. The development of the Lehigh Model was based on a review of previous work on data models and databases for structural experiments and a study of a number of large-scale structural experiments conducted at the ATLSS Center. The primary class hierarchy of the Lehigh Model consists of the project class level, the experimental task class level, the test condition class level, the test class level, and the data set level. Based on the earlier Lehigh Model, updated versions of the classes and attributes of the Lehigh Model are presented to better represent the information and data for large-scale structural experiments conducted at the RTMD earthquake simulation facility.;The Lehigh RTMD Metadata Web is an implementation of the updated Lehigh Model. Two examples of applying the Lehigh RTMD Metadata Web are presented. The first example is the Self-Centering Damage-Free Seismic-Resistant Steel Frame Systems project. The second example is the Studies on Large-scale, Real-time Pesudodynamic (PSD) Testing project, which focuses on hybrid earthquake simulation. |
