This study aims to further develop and demonstrate the recently-proposed smart rock technology for scour depth and protection effectiveness monitoring. A smart rock is one or two stacked magnets encased in a concrete sphere with a specially-designed rotational mechanism. Design guidelines, rotational mechanisms, remote measurement tools and localization algorithms of smart rocks were developed and validated at three bridge sites. The effect of steel reinforcement in bridge piers/deck on the orientation of gravity-controlled magnets was negligible. The localization accuracy with a single smart rock met a general requirement of less than 0.5 m in engineering applications. The spherical smart rock …

Direct Strength Prediction Of Cold-Formed Steel Beam-Columns, American Iron And Steel Institute
Direct Strength Prediction Of Cold-Formed Steel Beam-Columns, American Iron And Steel Institute
American Iron and Steel Institute (AISI) Specifications, Standards, Manuals and Research Reports (1946 - present)
The Direct Strength Method (DSM) of cold-formed steel member design employs local, distortional, and global cross-section elastic buckling analysis with empirically derived “direct” expressions to predict member strength. DSM is an accepted design method in national design specifications (e.g., AISI-S100-16) and enables a unified, robust, and flexible design approach. However, for beam-columns DSM in current design specifications employs simplified linear interaction expressions based on combining the isolated axial and bending elastic buckling and strength response. Today, local, distortional, and global elastic buckling under any combination of axial load and bending moments may be found using elastic buckling analysis tools such …
Characterization Of Cfs Framed Diaphragm Behavior, American Iron And Steel Institute
Characterization Of Cfs Framed Diaphragm Behavior, American Iron And Steel Institute
American Iron and Steel Institute (AISI) Specifications, Standards, Manuals and Research Reports (1946 - present)
Knowledge of the in-plane response to loading of cold-formed steel (CFS) framed diaphragm structures is essential for seismic and wind design. The information available specific to diaphragm design in the North American CFS design standards (AISI S240 & S400) is based on limited experimental work and the extrapolation of design methods developed for the wood industry. To address this shortcoming a test-based research project was performed in the Jamieson Structures Laboratory at McGill University focusing on the characterization of the behaviour under in-plane loading of CFS framed - wood sheathed diaphragms. This research was a complementary study to a research …

This paper presents measurements of high temperatures using a Brillouin scattering based fiber optic sensor and large strains using an extrinsic Fabry-Perot interferometric sensor for assessing the thermo-mechanical behaviors of simply supported steel beams subjected to combined thermal and mechanical loading. The distributed fiber optic sensor captures detailed, non- uniform temperature distributions that are compared with thermocouple measurements resulting in an average relative difference of less than 5 % at 95 % confidence level. The extrinsic Fabry- Perot interferometric sensor captures large strains at temperatures above 1000 C. The strain results measured from the distributed fiber optic sensors and extrinsic …
Shear Behavior Of High-Strength Self-Consolidating Concrete In Nebraska University Bridge Girders, Alex Griffin, John J. Myers
Shear Behavior Of High-Strength Self-Consolidating Concrete In Nebraska University Bridge Girders, Alex Griffin, John J. Myers
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Current reinforced and prestressed concrete design equations were developed for conventional concrete elements. Self-consolidating concrete (SCC) typically contains a lower coarse aggregate content and size than conventional concrete, which potentially hinders the aggregate interlock contribution to a concrete's shear strength. Thus, shear design equations must be verified with SCC mixtures. Two full-scale precast, prestressed concrete Nebraska University girders were tested to assess the shear behavior of high-strength SCC. Both girders were designed to permit two tests on each girder, both with and without shear reinforcement. Ultimate shear loads and crack patterns were documented and compared with code estimates, finite element …
Resistance Of Arc Spot Welds -- Update To Provisions, American Iron And Steel Institute
Resistance Of Arc Spot Welds -- Update To Provisions, American Iron And Steel Institute
American Iron and Steel Institute (AISI) Specifications, Standards, Manuals and Research Reports (1946 - present)
The provisions of the AISI S100-12 standard for strength of arc spot welds loaded in shear and tension have not been revised since the 1999 standard. Since then, four new research studies have created and tested arc spot welded connections, expanding the database of available tests. Therefore, a reconsideration of both the resistance equations and the resistance and safety factors using the enlarged data base was undertaken. This study performed a comprehensive analysis of the entire arc spot weld data base, where 450 specimens were categorized by their respective failure modes to assess current AISI S100-12 resistance equations. Performance of …

The American Iron and Steel Institute (AISI) Standards Council selected this project as one of four winning research proposals for its 2015 Small Project Fellowship Program. Project selections were based on several factors, including the potential for long-term impact on the industry; steel industry engagement and co-funding; and results for the AISI standards development committee, the student, and the academic institution. The objective of this project was to evaluate the provisions for determining the strength of arc spot welds in light of recent research studies. It is anticipated that the results of this study will impact the provisions in future …
