Second Order Irregular?Wave Generation in Flumes - Computation of Transfer Functions by an Asymptotic Summation Method
Recently the theory for second order irregular-wave generation (including superharmonics as well as subharmonics) has been rederived for a variety of different types of wave board motion....
Dynamic Loading of Airfield Pavements Caused by Aircraft Operations on Rough Runways
This paper presents results for dynamic pavement loading of various aircraft under takeoff and taxing scenarios. The data were obtained from computer simulation and applied to the Corps...
A Decision Support System for Reassessing the Operation of the Chungju Reservoir System
The Chungju Reservoir is a component of the Han River System in Korea. Chungju Reservoir consists of a main reservoir and a downstream smaller reservoir that serves as an after bay. It...
A Decision Support System for Multi-Purpose Reservoir Operations
A generalized decision support system (DSS) is presented for developing optimal operation policies for multi-purpose reservoirs. The model is designed for single reservoirs, although is...
Evaluating the Steady State Stochastic Dynamic Programming Model for the High Aswan Dam
The paper describes the results of a study to critically evaluate and test the Steady State Stochastic Dynamic Programming model (SSDP). Whenever a reservoir computer model is developed,...
Concurrent E-I Algorithm in Structural Dynamics
A concurrent explicit-implicit algorithm for time integration of the differential equations arising from a finite element discretization is described. The first step of the method consists...
Computer Applications in Structural Analysis and Design
The computer programs have been increasingly used in structural analysis and design to improve productivity. The computer applications in areas of automatic member and foundation design...
Impulse Effect on Redundancy of a Tied-Arch Bridge
This paper studies the redundancy of a tied-arch bridge using a 3-dimensional finite element computer model. By using static incremental loading simulation, a tied-arch bridge designed...
Design and Implementation of a Database for Seismic Evaluation of Structures
The seismic evaluation of large structures, such as bridges, requires a comprehensive framework for managing the data. An evaluation typically involves the dynamic analysis of a number...
Discrete Modeling of Soil-Structure Interaction Under Dynamic Loading
A proposal of discrete modeling useful to describe behavior of structures burried in the ground under air explosion is presented. In the modeling emphasis is laid on determining the space...
Developing an Object Based Planning System for Precast Concrete Building Structures
This paper presents the organization of an object based planning system for determining the preliminary costs, schedules and resources for precast concrete building structures. First,...
Numerical Modeling of Initial Ground Movement in an Instrumented Superconducting Super Collider Shaft
A 5.5 m diameter shaft was sunk into a rock formation of Taylor Marl to a depth of 61 m at the Superconducting Super collider (SSC) site. Numerical modeling using finite difference analysis...
Mat Foundation Design: An Historical Perspective
Nearly a half century ago, Karl Terzaghi rationalized the analysis and design of mat foundations with the conclusion that subgrade reaction was the most important variable. Soon after...
Displacement of Landmark Building Resulting from Adjacent Construction Activities
This paper describes the observations and presents comments related to the measurement of settlement and the avoidance of damage to a historic structure in the City of New York from adjacent...
Horizontal and Vertical Movements of Bridge Piers Subjected to Ship Impact
Results of a detailed analysis to evaluate the potential horizontal and vertical movements of the piers of George P. Coleman Bridge, Virginia, in the event of ship impact are presented...
Pile Settlement Based on Dynamic Measurements
Dynamic measurements during driving are well established for monitoring driving performance and the prediction of pile capacity. Post driving, signal matching office methods (e.g. CAPWAP)...
Static Pile Load-Movement From Dynamic Measurements
Static loading tests have traditionally been performed to determine the characteristics of pile load-movement relationships. Due to the expense involved and time required, this type of...
Damage Evaluation of Building on Piers in Expansive Clay
A number of columns in the crawl space of a pier-supported structure founded in expansive clays were damaged as a result of ground movements since the building was constructed in 1975....
Settlement of Dynamically Compacted Deposits
This paper compares predicted and measured settlements of deposits that were densified by means of dynamic compaction. Settlement records are presented for sites consisting of old, midage,...
On Measurements of Particle Spinning Motion
Investigation of particle saltation motion is crucial to the development of the theory of bed load transport. Due to the combination effects of the bed roughness and the velocity gradient,...
