Most stormwater infrastructures are aging and deteriorating in the United States. The American Society of Civil Engineers (ASCE) announced its 2021 Report Card for America's Infrastructure that infrastructure has received a 'D' grade. primary study objective is to help decision-makers deal effectively with control measures limited-budgeted, ambiguous inconsistently applied operation maintenance...

A damage diagnosis approach using time series analysis of vibration signals was recently proposed by the Los Alamos National Laboratory. In this paper, the application of this approach to the damage detection of the benchmark problem designed by the ASCE task group on health monitoring is explored. The damage detection approach is modified to consider the influence of excitation variability and...

The effective production of many motor behaviors requires the strict coordination of discrete motor pattern generating circuits (Hill et al. 2003). Locomotor behaviors usually require this coordination at several levels of the nervous system, within single limbs (interjoint coordination), across multiple limbs (intersegmental coordination), and between multiple central pattern generator (CPG) c...

Structural engineers face significant challenges in the 21 st century and among them, global environmental challenges must be a priority for our profession. On a planet with finite natural resources and an ever-growing built environment, engineers of the future must consider the environmental, economic, and social sustainability of structural design. To achieve a more sustainable built environm...

This grant studies the behavior of emergent communication systems (communication networks without centralized control, like Internet or ad-hoc networks). We consider systems formed by a number of nodes that communicate and interact locally through links. The nodes route and schedule the transmission of data packets accross the links, to reach a consistent global behavior. Our objective is to en...

Cooling towers are high and thin structures which widely used at the industry nuclear facilities. These built on column elements as reinforced concrete. Determining behavior of buildings affected by dynamic loads such wind earthquake is very important in terms preventing loss life property. In this study, hyperbolic cooling with 117m height tower was examined behaviors structure effects were in...

This paper investigates the collapse risk of seismically isolated buildings that are designed by procedures ASCE/SEI 7-16 standard for sites within 5 km active fault controls hazard. The study is based on six-story perimeter frame with special concentrically braced frames a location in California. seismic isolation systems considered this comprised either: (i) triple friction pendulum bearings ...

Abstract While Dhaka, the capital city of Bangladesh, adapts to more and high-rise buildings skyscrapers, concerns remain about their design efficiency ability withstand shear loads from seismic movements. In this study, several orientations placements walls in a regular G +15 story reinforced concrete building were assessed observe nature structure subjected earthquake by adopting Equivalent S...
