I have been working on a project about the seismic performance of 3D printed concrete (3DPC) structures. Since there are currently very few code provisions covering the design of such type of structure, our ultimate goal is to develop rational seismic design factors for this type of structure such that they can be used as a reference in developing future code. My primary duty in this group is to create and validate finite element models, produce a design methodology for residential 3DPC building archetypes, and use them to evaluate building performance and selected R factors per the FEMA P695 methodology. I have greatly improved my research and analytical skills during this process and kept my interest in this field.

Load-bearing Horizontal-hole masonry structure and its seismic performance (2017-2019) Conducted compression test of 57 building blocks, a shear test of 84 specimens, and a push-over test of a dozen load-bearing horizontal-hole interlocking hollow block walls Supervised a junior graduate student to conduct safety identifications of three high-rise buildings of the shear wall structure Review and correction of structural drawings (2016-2017) Reviewed the structural drawings of various types of buildings, identify defects and potential structural risks in designs per code provisions and company standards Instructed two undergraduates to model and analyse buildings using the engineering software PKPM
