Equating Dynamic Analysis to Static Code Provisions
Building codes generally prescribe seismic design provisions that include a static lateral force procedure that can easily be combined with the gravity loads to design the structural elements....

1988 SEAOC and UBC Seismic Provisions
This paper highlights the major improvements to seismic design provisions incorporated in the 1988 Structural Engineers Association of California (SEAOC) 'Blue Book'...

Recent Developments in Isolation Hardware
Most isolation systems have at least two physical components: one specifically intended to add flexibility and the other to control the resulting deflections. However, other elements may...

Shake Table Testing of a Friction Pendulum Seismic Isolation System
Building models using the Friction Pendulum System (FPS) were tested on the shaking table at the Earthquake Engineering Research Center of the University of California, Berkeley. This...

Response of Concrete Buildings to Lateral Forces
ACI-ASCE Committee 442 (Response of Concrete Buildings to Lateral Forces) has just issued its report (ACI-ASCE 442 1988a). In that Report, the performance of reinforced concrete buildings...

Seismic Response Study of Two Memphis Sites
This paper presents a study to evaluate the soil effects on earthquake ground motion of two selected sites in the Memphis area. Twenty artificial bedrock acceleration time histories with...

Selected Papers from Chinese Journals of Structural Engineering
This book is an initial effort to introduce selected papers from journals published by the China Civil Engineering Society to ASCE membership. The twenty papers in this volume were selected...

Seismic Engineering
Research and Practice
This volume of Seismic Engineering: Research and Practice contains papers from twenty-two sessions of the 1989 ASCE Structures Congress. These papers represent a wide-ranging interest...

The State of Art of Physical Modelling of Sediment Transport
The paper attempts formula some ideas about the state of the art in the field of physical modelling of sediment transport processes. Up to now the physics of sediment transport are not...

Mid-Scale Laboratory Tests on a Two-Dimensional Movable-Bed Sand Model
A two-dimensional physical model was used to simulate wave-induced scour in front of a concrete dike sloped at 1:4. The tests were conducted at the U.S. Army Engineers Waterways Experiment...

Earthquake Effect on Sediment in Rivers and Deltas
Many authors have studied the age and distribution of the Holocene deltaic deposits of the Mississippi River. Several others have written about the magnitude and the recurrence interval...

Riprap Stability in Channel Bends
A systematic test series is underway in a large test channel to define the stability of riprap on the outer bank of channel bends. A 'practical equilibrium' concept...

The Use of Distributed Rainfall-Runoff Models Based on GIS at Different Scales of Information
The effects of spatial variability of soil type and land use on basin response are investigated. This is modelled thorugh a distributed approach specifically designed for calibration from...

Hydraulics of Side-Channel Weirs for Regional Detention Basins
Side-channel weirs can be used for diversion to reduce flood peaks. A 1:25 scale model was built to investigate the hydraulic characteristics of embankment-shaped side-channel weirs. Results...

Hydraulic Model and Prototype Experience on Old River Overbank Structure
Physical hydraulic model tests of the Old River overbank structure were conducted to investigate the hydraulic performance of the stilling basin and evaluate riprap stability and scour...

Scale Effects at Intakes Due to Boundary Layer Growth
Boundary layer development in hydraulic models of intakes based on Froude criteria can be poorly scaled because it is viscosity dependent. The potential for scale effects can be estimated...

A Comparative Hydraulic Model Study of an Orifice Spillway
The results of a hydraulic model study to investigate the feasibility of using an orifice spillway at a generating station in northern Manitoba, Canada are presented. It has been suggested...

Flow Characteristics in an Irregular Spillway Model
A physical model of the spillway for a proposed water supply reservoir near Meridian, Texas, was constructed to determine the optimum spillway design which would maintain an acceptable...

Hydraulic Model Studies - Sidney A. Murray Jr., Hydroelectric Plant
The power plant is located at the Old River Control of the Lower Mississippi River (Louisiana). It consists of an intake channel about 5000 ft long, a power plant with eight bulb units...

Physical Model Study of New York State Dam
The New York State Dam is located on the Mohawk River near its confluence with the Hudson River. Downstream from the dam, the river flow is divided into six channels as the water passes...
