General Description

Developing modeling parameters and acceptance criteria for structural components under three-dimensional seismic demands

PREP Research Associate

This position is part of the National Institute of Standards (NIST) Professional Research Experience (PREP) program. NIST recognizes that its research staff may wish to collaborate with researchers at academic institutions on specific projects of mutual interest, thus requires that such institutions must be the recipient of a PREP award. The PREP program requires staff from a wide range of backgrounds to work on scientific research in many areas. Employees in this position will perform technical work that underpins the scientific research of the collaboration.

A researcher is sought for a position in Structural Engineering to develop nonlinear modeling parameters and acceptance criteria for RC columns and walls under 3D loading that can be adopted in ACI 369 and ASCE 41. This effort advances seismic performance assessment of existing buildings by reducing the inherent unconservatism that currently exists in performance-based seismic codes and standards due to the lack of provisions that account for multi-directional loading of structural components during earthquakes. This effort includes the development of a database of experimental tests, development of nonlinear finite element models, conducting sensitivity analysis, and development of nonlinear modeling parameters and acceptance criteria.

Key responsibilities will include but are not limited to:

§  Develop a database of past tests on RC columns under bidirectional loading.

§  Develop high-fidelity finite element models that are calibrated to the collated dataset base.

§  Conduct parametric studies on high-fidelity models to develop an extensive database of virtual experiments on RC columns under bi-axial bending

§  Develop data-driven ASCE 41 modeling parameters and acceptance criteria

§  Co-author a paper of peer-reviewed journal quality summarizing the results.

Qualifications

§  A Ph.D.in Civil Engineering with a focus on Structural Engineering or a related field

§  Involvement with relevant code and standard committees

§  A strong background in seismic performance of structures and nonlinear assessment of structures

§  The ability to work independently to achieve project objectives, meet project deadlines and reporting requirements.
