Seismic Design Coefficients For Speedcore Or Composite Plate Shear Walls - Concrete Filled (C-Psw/Cf), Shubham Agrawal, Morgan Broberg, Amit H. Varma
Bowen Laboratory Research Reports
This report summarizes the results from FEMA P695 analytical studies conducted to verify the seismic design factors for composite plate shear walls – concrete filled (C-PSW/CF), also referred to as Speedcore. ASCE 7-16 provides the seismic design factors, which include the seismic response modification factor, R, deflection amplification factor, Cd, and overstrength factor, Ωo, for various approved seismic systems. C-PSW/CFs are assigned a response modification factor of 6.5, a deflection amplification factor of 5.5, and an overstrength factor of 2.5 for C-PSW/CFs. These seismic design factors were selected based on the seismic performance of similar structural …
Experimental Assessment Of The Current Load Rating Procedures For A Corroded Steel Ridge Girder In Massachusetts, Brendan T. Knickle
Experimental Assessment Of The Current Load Rating Procedures For A Corroded Steel Ridge Girder In Massachusetts, Brendan T. Knickle
Structural Engineering Masters Projects
The work conducted for this project involves an experimental assessment of the Massachusetts Department of Transportation’s (MassDOT) existing procedure for determining the resistance of a corroded steel girder end when load rating a bridge. Three steel girders with significant corrosion developed over a 79-year service life were obtained from a recently rehabilitated bridge and loaded to determine the girders corroded resistance. A testing rig was designed in the UMass Amherst Brack Structural Testing Laboratory to both apply a shear dominated load to the corroded girder and withstand the developed lateral loads throughout the analysis. Reaction force data obtained from the …
