As part of academic work, tested sixteen 4 x 8.08ft (1.22 x 2.46m) wood shear walls both monotonically and cyclically under three different sheething nail spacings. Some walls were incorporated with rods & boots to resist seismic and wind loads. Tested twelve 8 x 8.08ft (2.44 x 2.46m) walls also under three different nail spacings. For the dynamic-displacement protocol of these 8 x 8.08ft (2.44 x 2.46m) walls, two different filtered EQ records were used. The core of the thesis was the development of a mechanistic seismic damage model based on a retrofit of Park & Ang's (1985) damage equation for concrete connections. In simpler terms; working on an equation that quantifies structural damage after the occurrence of an earthquake.

Also tested double-T concrete beams in-flange connectors which are mostly found in bridges and parking structures. These connectors are used to attach one double-T beam to another by the use of welds. A total of seven tests for each of six connectors were performed. The connectors were tested in 4 x 36 x 38in (10.16 x 91.44 x 96.52cm) pre-cast sample slabs. For all the above mentioned projects, DASYLab was used for both signal generation and data acquisition.

Designed the new-addition, seen in railroad red, to the Self-Reacting Frame (SRF), seen in safety yellow, in I-deas. The SRF is equiped with two 55kip (244.65kN) hydraulic actuators having 10in (25.4cm) of stroke. Have also designed the fixture providing the three different test positions for the T-beams concrete specimens.
