Two new types of connection between concrete-filled U-shaped steel (CFUS) beams and square tube (CFSST) columns were presented in this study, including rebar-sleeve with internal diaphragm rebar-through connection. Based on the experiments rebar-plate connections CFUS CFSST under cyclic loading, nonlinear finite element models tested specimens developed validated by comparing them experimental ...
Macrocell corrosion of steel rebar in concrete induced by corrosive environments has attracted widespread attention the engineering community due to its rapid rate, diverse forms, and multiple incentives. Potential differences between dissimilar coupled or different parts same mainly cause macrocell rebar. The more significant potential difference, faster rate macrocell. Based on existing resea...
Clinical scale zinc finger nuclease (ZFN)-driven gene-editing of PD-1 in tumor infiltrating lymphocytes (TIL) for the potential treatment of metastatic melanoma Joal D Beane, Gary K Lee, Zhili Zheng, Nimisha Gandhi, Daniel Abate-Daga, Mini Bharathan, Mary Black, Matthew Mendel, Zhiya Yu, Sadik H Kassim, Smita Chandran, Martin Giedlin, Dale Ando, Ed Rebar, Andreas Reik, Michael Holmes, Philip D ...
Surface nanocrystallization (SNC) modification can be used to realize the high-efficiency derusting of rusted Cr-alloyed rebar and obtain nanostructured grains on surface rebar. The corrosion resistance performance SNC in a simulated Cl--containing concrete pore solution was evaluated basis electrochemical experiments. Potentiodynamic polarization testing showed that passivation current density...
Prefabricated concrete structures are driving the development of green buildings, and connection between prefabricated components is main factor affecting safety performance these structures. Grouted sleeve technology can effectively improve precast component connections. In process grouting operation, grouted sleeves affected by construction environment often have various defects. this work, t...
To augment current methods for the evaluation of reinforcing bar (rebar) corrosion within concrete, we are exploring unique features in the dielectric and magnetic spectra of pure iron oxides and corrosion samples. Any signature needs to be both prominent and consistent in order to identify corrosion within concrete bridge deck or other structures. In order to measure the permittivity and propa...
Recent years have seen an increase in demand for the demolition of obsolete and potentially hazardous structures, including reinforced concrete (RC) using blasting techniques. However, because risk failure is significantly higher when applying to demolish RC structures than mechanical dismantling, it critical achieve optimal design conditions by taking into account major factors affecting a str...
