5 Warm climates pose challenges to building energy consumption and pedestrian comfort. 6 Knowledge of the wind flow around buildings can help address these issues through 7 improving natural ventilation, energy use and outdoor thermal comfort. Computational Fluid 8 Dynamics (CFD) simulations are widely used to predict wind flow around buildings, despite 9 Researcher, Singapore-ETH Centre, Futur...

Many branches of engineering, mathematics, and sciences, have relied on benchmark problems as a standard means to compare different solution techniques. Since 1996, the ASCE Structural Control and Monitoring Committee and Task Group on Benchmark Problems, the U.S. Panel on structural control, and IASCM have developed a series of benchmark control problems that offer a set of carefully modeled r...

This study investigated the role of duration and tornado-induced static pressure on peak pressures on a low-rise building. A tornado simulator was used to generate both translating and stationary vortices to measure pressure time series on a building model. Time-resolved velocity measurements were also made on the vortex to aid in the analysis. Past studies have suggested that peak pressures on...

While significant progress has been made in understanding the theoretical properties of different argumentation logics and in specifying argumentation dialogues, there remain major barriers to the development and practical deployment of argumentation systems. One of these barriers is the lack of a shared, agreed notation or “interchange format” for argumentation and arguments. In the last years...

A fragility analysis methodology is developed for assessing the response of light-frame wood construction exposed to stipulated extreme windstorms and earthquakes. Performance goals and limit states (structural and nonstructural) are identified from a review of the performance of residential construction during recent hurricanes and earthquakes in the United States. Advanced numerical modeling ...

Automated openand closed-loop control systems can enhance the performance of irrigation delivery systems. This paper examines the response of the canal test cases developed by the ASCE task committee on canal automation algorithms to a particular anticipatory open-loop control technique, gate stroking. The performance of the ideal gate-stroking solution is compared with the performance of an ap...

In this paper, a novel approach to the characterization of structural damage in civil structures is presented. Structural damage often results in subtle changes to structural stiffness and damping properties that are manifested by changes in the location of transfer function characteristic equation roots (poles) upon the complex plane. Using structural response time-history data collected from ...

Modeling parameters (MP) of reinforced concrete columns are a critical component performance-based seismic assessment methodologies because in these approaches damage is estimated based on element deformations calculated using non-linear models. To ensure model fidelity and consistency results, methods ASCE 41, ACI 369.1, 374.3R prescribe modeling calibrated experimental data. This paper introd...
