Development of a Steel Bridge System Simple for Dead Load and Continuous for Live Load. Volume 2: Experimental Results Final Rept

摘要

This report summarizes the results from tests completed on rolled I-shaped girders representing the interior pier (negative flexure) region of a two-span bridge. The goal of this examination is to economize the use of steel in bridges commonly designed and constructed in the U.S. This report documents the details of the connection analysis and design, test setup, laboratory and field testing, and test results. Chapter 2 contains a summary of trial designs completed within the span range determined from the market analysis. The trial designs were completed according to AASHTO LRFD Bridge Design Specifications (1998). The common setup and procedures used in testing of the different designs are summarized in Chapter 3. Chapters 4, 5 and 6 review the testing of specimens one, two and three, respectively. Each of these chapters cover test setup, instrumentation, material testing, and specimen construction specific to each sample. Each of these chapters also reviews and analyzes the data obtained from testing. Appendix A contains the calculations completed for the trial designs.
