Thermal-Structural Analysis Methods for RCC Dams
Current procedures for evaluating temperature control and the placement of contraction joints in roller compacted concrete dams are not always evaluated with the aid of detailed analysis...

Roller Compacted Concrete III
This proceedings, Roller Compacted Concrete III, includes papers presented at the ASCE Specialty Conference held in San Diego, California on...

Numerical Beach Profile Modelling for Beachfill Projects
The use of beachfill in addressing coastal erosion problems is becoming increasingly popular. It is often more attractive than the conventional structural approaches for economic, aesthetic...

Application of a Beach Plan Evolution Model in Sergipe, Brazil
An offshore breakwater 543 m long located at about 2.4 km from the shore at 10 m of water depth (above chart datums) provides protection to a liquid bulk terminal (Terminal Portuarlo de...

Comparison of Model and Field Results for Barbers Point Harbor
As waves travel into harbors from deep water, nonlinear processes lead to transfers of energy from the wind wave frequencies to long waves with periods of the order of several minutes....

A Dual Approach to Low Frequency Energy Definition in a Small Craft Harbor
Low frequency wave energy in a small craft harbor is examined through comparison between a numerical model and a 3-dimensional physical model. A hybrid element steady state linear monochromatic...

Numerical Modeling of Proposed Kawaihae Harbor, HI
The Kawaihae shallow-draft harbor site is located on the northwest coast of the island of Hawaii, HI. An entrance channel, turning basin, and breakwater currently exist at the harbor site....

Development of Detached Breakwater Design Criteria Using a Shoreline Response Model
An evaluation of beach response to detached breakwaters was conducted using the numerical shoreline response model GENESIS. Functional design parameters such as structure length, gap distance,...

Robust Approach to Wave Runup Calculation
Wind wave runup on a natural beach is examined for the case of an irregular wave forcing function. A pragmatic approach to the calculation of the runup time series and the corresponding...

Application of Extremely Low Altitude Photogrammetry for Monitoring Coastal Structures
Extremely low altitude mapping photography exposed from a helicopter is showing considerable promise in providing another method of extending the many benefits of photogrammetric data...

The Application of Technology to Solving Practical Problems
In this paper, the roles of the scientist, technologist, engineer, and manager are discussed to place them in perspective. A distinction is made between the coastal engineer' and practicing...

A Case of the Shakes
New York City's unusual Terrace on the Park offers dining and dancing in a catered ballroom that stands six stories above the ground on four supercolumns. But when guests...

Peaches and Concrete
One Peachtree Center, Atlanta's latest highrise tower, will measure 62 stories high (860 ft) with 1.42 million sq ft of office space when completed next July. It will also...

L'Ambiance Plaza: What Have We Learned
In April 1987, a structure called L'Ambiance Plaza collapsed during construction, killing 28 workers. The building, in Bridgeport, Conn., was being built using the lift-slab...

Study of Three Dimensional Crack Tip Location of Mortar by Acoustic Emission
Plain mortar specimens were tested under three-point bending. Experimental variables include the width of the specimen and the notch-to-depth ratio. The experimental results of 12 specimens...

A Critique of the Ultrasonic Pulse Velocity Method for Testing Concrete
The pulse velocity method is the most widely used ultrasonic nondestructive method for assessing concrete quality. However, it has been well established that the relation between ultrasonic...

Frequency Spectrum Analysis of Ultrasonic Testing Signal in Concrete
Description is given on high-speed sample apparatus connected with the CTS-25 low frequency ultrasonoscope and computer, the time domain of ultrasonic testing signal is transformed to...

Condition Monitoring of Structures Using Transient Response
Condition monitoring of structures by measuring transient response and tracking the derived modal parameters has been applied with success in three laboratory studies. Where modal parameters...

Numerical Simulation of Dynamic Shear Transfer
This study was focused on the dynamic response of concrete interfaces under the effects of impulsive loads, and the relationship between the interface shear transfer and the response in...

Pullout Testing of High-Strength Concrete Members
An experimental investigation of a high-strength concrete mixture was undertaken to measure and evaluate pullout and compressive strength properties. Two columns, a slab, and cylindrical...
