Reliability-Based Shear Rating Of Prestressed Concrete Bridge Girders Considering Capacity Adjustment Factor, Alaa I. Chehab, Christopher D. Eamon
Civil and Environmental Engineering Faculty Research Publications
In this study, the reliability of prestressed concrete (PC) bridge girders in the shear rating process is quantified, where the use of a simple procedure to enhance the accuracy of shear capacity evaluation for rating is evaluated. It was found that the approximate methods used in code-based procedures to develop shear resistance used for reliability calibration of the AASHTO Bridge Design Specifications and the Manual for Bridge Evaluation result in larger discrepancies in reliability than previously assumed, as well as substantially conservative shear capacity evaluation in most cases. To examine the effects of using a more accurate shear rating process, …

Performance Of Cold-Formed Steel-Framed Shear Walls: Alternative Configurations, Kelly A. Morgan, Mark A. Sorhouet, Reynaud Serrette
American Iron and Steel Institute (AISI) Specifications, Standards, Manuals and Research Reports (1946 - present)
This report presents the results of twenty shear wall tests that were conducted to evaluate the performance of wall configurations not currently (2002) permitted in the building codes. Ten (10) walls were evaluated under reversed cyclic loading and the other ten (10) under monotonic loading. Brief descriptions of the test program and results are presented in the following paragraphs. The reversed cyclic load tests comprised 4 ft. x 8 ft. 54- and 68-mil framed walls with 7/16-in. OSB rated sheathing on one or both sides of the wall and 33-mil framed walls with 27-mil sheet steel. The sheet steel wall …
