Abstract: Several functional problems have been reported on pin and hanger system truss bridges, such as frozen pins, stress spikes in hangers, lack of expansion joint movements, etc. It has been difficult to develop a pin and hanger ...

Abstract: The wind load provisions of ANSI A58.1, published in 1982, contain the latest available pertinent data and technical knowledge. Summary of changes from the previous standard and background material for wind speed map, ...

Abstract: Falling weight deflectometer (FWD) testing has been done extensively in the past to assess structural condition and determine the moduli of pavement layers. The set of modulus values for pavement layers obtained from the ...

Abstract: Uncertainties are inherent in computational fluid dynamics (CFD). These uncertainties need to be systematically addressed and managed. Sources of these uncertainties are identified and some aspects ...

Abstract: In this research, the seismic performance of a proposed efficient energy dissipating steel-braced frame (EEDBF) in relation to that of a moment-resisting frame (MRF) and chevron braced frame (CBF) is studied. The frame is ...

Abstract: This paper estimates their contributions to total gross state domestic product in an attempt to revisit the issue of cities as the engine of growth. Because direct evidence on this aspect is missing, this paper uses the ...

Abstract: Gridded time series from the Global Ocean Surface Temperature Atlas were analyzed with a variety of techniques to identify spatial structures and oscillation periods of the tropical Atlantic sea surface temperature (SST) ...

Abstract: Zonally symmetric sea level pressure perturbations have been observed to oscillate at 3?6-yr periods and travel from one polar region to the opposite polar region in approximately 10 years. Based on previous modeling of ...

Abstract: AbstractSteel beam column welded connection fails in steel moment resisting frame construction under earthquake strain. In this case, the analysis was performed with a steel web opening beam column welded connection and ...
