This paper presents an experimental study for the structural performance of reinforced concrete (RC) exterior beam-column joints rehabilitated using carbon-fiber-reinforced polymer (CFRP). The present experimental program consists of testing 10 half-scale specimens divided into three groups covering three possible defects in addition to an adequately detailed control specimen. The considered de...

The inelastic response of beam-column connections significantly affects the seismic performances of steel frames. Accurate models of beam-column connections are important both in understanding the seismic behavior and in design. An effective approach towards developing accurate models for connections is self-learning simulation, which is presented in this paper. The latter simulation method has...

Hurricane top structures are not well captured by airborne or dropsonde observations. Total column ozone (TCO) observations provided the Ozone Mapping and Profiler Suite (OMPS) Nadir Mapper (NM) onboard Suomi National Polar-orbiting Partnership (S-NPP) satellite employed in an investigation of hurricane structures. We show that OMPS NM TCO data can capture Maria (2017) over Atlantic Ocean. An o...

This paper compares base shear computed from floor accelerations (inertial base shear) and column shears (structural base shear) for several single-degree-of-freedom (SDF) systems and two mid-rise, multi-story buildings due to a suite of 30 earthquake ground motions. The presented results show that the inertial base shear is close to structural base shear in short-period (<1 sec) SDF systems bu...
