• DESIGN EXPERIENCES

  • Sep 2015 - Aug 2019

  + Precast R/C Column: Design using AASHTO/Seismic Guide Spec. and detailing a large-scale two-column bent with column to ABC-CIP hybrid cap beam grouted duct connection and rebar hinge pocket connection as part of a two-span bridge to be tested on a shake table at UNR, 2015.+ Precast Footing: Design using AASHTO/Seismic Guide Spec. and detailing a large-scale footing with pockets for precast columns to be tested on shake table at UNR, 2015.+ Precast/CIP Cap beam: Design using AASHTO/Seismic Guide Spec. and detailing a large-scale cap beam partly precast and with grouted ducts, and partly cast-in-place to be tested on shake table at UNR, 2016.+ Steel Girders with Cross Frames: Design using AASHTO Guide Spec. and detailing the steel superstructure for a large-scale two-span bridge to be tested on shake table at UNR, 2015+ Girder-to-Cap connection: Design of an innovative steel girder to cap beam connection that allows girders to be simply supported for the dead load and continuous for the live load and seismic loads as part of a large-scale two-span bridge model to be tested on shake table at UNR, 2016+ Full-Depth Precast Deck Panels: Design using AASHTO Guide Spec. and PCI design handbook and detailing deck-to-girder connections with pockets filled with high-strength grout and panel-to-panel connections with UHPC filled transverse joints * In all the design experiences CSI Bridge Design, OpenSees, and SAP2000 have been used frequently. + Design guidelines were developed for the two most critical connections (column to hybrid cap beam grouted duct connections, and column-to-footing rebar hinge pocket connections) based on the measured test results and analytical parametric studies.
