Knowledge Representation for Bridge Design
An implementation of a frame-based knowledge representation language (KRL) for development of expert system applications in highway bridge design is presented. The frame-based KRL is used...
Integration of CAD and Structural Engineering for Building Design
Many design/build contractors have publicized successes using three-dimensional (3D) computer-aided-design (CAD) models. Structural engineers contribute equipment support structures as...
Projecting Climate Change to Small Basins: Potential Impact of Global Warming on Hurricane-Induced Flooding in South Florida
An important difficulty in evaluating potential hydrologic impacts of climate variability is that predictions of climate change require global simulation models that do not resolve phenomena...
Uncertainty in Urban Hydrologic Modeling
Uncertainty is pervasive in hydrologic modeling. Uncertainty is present in the formulation of the physical situation to be modeled, in the form of the model to be used, in the boundary...
Numerical Solutions for Transient and Nearly Periodic Waves in Shallow Water
This paper presents a study of several numerical methods for solving transient (time-dependent) model equations for waves in shallow water by means of the method of lines. The physical...
Parametric Excitation of Collapsible Latex Tubes
In 1985, Liu and Ding (1989) made an experiment of collapsible tubes containing a pulsatile flow. A latex tube is sealed up in a plexiglass chamber. If the transmural pressure (TP) of...
Dynamic Behavior of a Non-Linear Cable Truss
The equations of motion of a geometrically non-linear cable truss are presented. The behavior of the truss subject to harmonic excitation is studied....
Cumulants of the Nonlinear Combination of Independent Random Variables
A random variable of interest is often the sum of linear or nonlinear combinations of many independent random variables. In calculating the statistics of this random sum, advantages of...
Response of Nonclassically Damped MDOF Systems to Nonstationary Random Excitation
A procedure for calculating the dynamic response of a nonclassically damped multi-degree-of-freedom (MDOF) system to nonstationary non-white vector-valued random excitation is developed...
The Application of Computerized Tomography for Determining Material Properties
X-ray computerized tomography (CT) is an imaging technique that has been used by the medical community for a number of years and is well documented. However, the adaption of this technique...
A Phenomenological Approach to Physico Chemical Phenomena Coupled with Damage in Massive Concrete
This paper presents the first experiments which have been done to support the bases of a thermomechanical model coupled with damage and to identify the characteristics parameters needed...
Model Comparisons of Harbor Wave Response
Physical and numerical model tests were conducted for an idealized, flat-bottom rectangular harbor, entrance channel, and nearshore bathymetry. Bathymetry of the entrance channel and offshore...
Basic Physical Models in Sediment Transport
Basic particle dynamics and cellular automata micromodels of clastic sediments are described and applications are illustrated in the areas of aeolian saltation, bedload transport, size...
Long Wave Effects in Laboratory Studies of Cross-Shore Transport
A movable bed physical model study was conducted to investigate the influence of trapped low frequency energy on wave transformation and beach profile evolution. Using identical drive...
Physical Modelling of Pocket Beaches
The design of artificial beach systems is dependent upon the modelling criteria and on the selection of the sand material to be used for nourishment. In order to obtain a stable beach...
Comparison of Shoreline Change Obtained with Physical and Numerical Models
This paper describes a study performed to compare numerical simulations of shoreline response to coastal structures to the response measured in a large wave basin. Two cases are modeled...
