Abstract: A finite element model capable of tracing the nonlinear response of coupled shear walls to earthquake motions is proposed. The walls are idealized as an assembly of quadrilateral elements with three degrees of freedom, two ...

Abstract: High-fidelity forecasts of construction cost indexes and material prices are critical for the successful delivery of infrastructure work projects. Unfortunately, existing models tend to underperform because they either ...

Abstract: Decision-support tools for infrastructure planning assume that the real cost of construction (i.e., the cost of construction when adjusting for inflation) will remain constant over the life cycle of a facility. This ...

Abstract: Construction cost indices support planners, engineers, and policymakers in improving the management of highways. This study details the creation, analysis, and application of four new quarterly highway construction cost ...

Abstract: The collection of infrastructure performance data is critical for agencies to cost-effectively maintain and preserve their existing assets. This paper presents a decision-support tool developed to support a state planning ...

Abstract: Measurements of drift were made in a wind and wave facility at different elevations below the mean water level. The drift profiles were obtained for reference wind speeds, Ur=3.1, 5.7 and 9.6 m sec?1. The measurement ...

Abstract: The magnetics of power electronics has particular potential for improvement, as these components are typically the largest and volumetrically inefficient in a power circuit. Nowadays, the trend ...

Abstract: Many bridge management systems (BMSs) use a Markov chain model to forecast the deterioration process. The Markov property may be considered to be restrictive when modeling the deterioration of transportation assets, primarily ...
