Current Research

Professor Pedro Silva is interested in the development of innovative procedures for the design of civil structures to resist man made as well as natural hazards. Current research includes the development of numerical tools for practitioners and researchers to use in the assessment/design of reinforced concrete (RC) slender bridge columns using new state of the art seismic design practice. The research approach progresses from simple computational tools to high-fidelity modeling of the inelastic response of RC Columns. Linking of these computational tools to a rigorous experimental program will provide the necessary data to validate and calibrate the new models. The experimental program consists of pseudo-static and shake-table tests with proper consideration of slenderness, axial load, reinforcement ratios, and P-Delta effects on damage levels and associated plastic hinge length. Research will result in methods which are general enough to apply across multiple size columns and that can be used for bridge and/or building design. Products of research include new models for plastic hinge length relations that balance design convenience and analytical rigor, while providing accuracy in their ability to relate to damage.
