Numerical And Experimental Analysis Of A Retrofit System For Light-Framed Wood Structures Under Wind Loading, Joshua D. Rosenkrantz
Numerical And Experimental Analysis Of A Retrofit System For Light-Framed Wood Structures Under Wind Loading, Joshua D. Rosenkrantz

the sheathing and rafters, and toenail connections between the rafters and stud walls. However, these connections have poor resistance to uplifting forces, as occurs in high wind speed events, causing sheathing or roof-to-wall-connection (RTWC) failures. The improvements made to building codes after Hurricane Andrew affected only new construction, and the economic losses caused by roof failures in homes built prior to 1993 from Hurricane Katrina pointed to a need to retrofit older structures. This paper will investigate the design, analysis, and testing of a temporary cable-netting roof harness as an alternative to other relatively expensive and invasive retrofitting options. To …
Seismic Behavior Of Concrete Frames With Jacketed Columns, Jose Alvarez
Seismic Behavior Of Concrete Frames With Jacketed Columns, Jose Alvarez
Doctoral Dissertations
Research on jacketed reinforced concrete (RC) columns is well established and growing. The existing studies describe the ability of jackets to rehabilitate RC columns for seismic demands. The system in the studies has proven to upgrade both strength and ductility of their unretrofitted counterparts, concentrated on repairs of deficiencies, currently in columns designed with old code provisions. These deficiencies include: low shear strength, insufficient core confinement, and short lap-splices, in particular within the plastic hinge zone. Columns with these deficiencies usually have brittle failures and cannot develop displacement ductility ( ) greater than 2. Research results on columns retrofitted with …
