Study of the Seismic Behavior of Retrofitted Reinforced Concrete Buildings
Over ten years experimental research in Japan on the seismic behavior of retrofitted reinforced concrete buildings is reviewed. Emphasis is put on the improved strength and/or ductility...

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...

Seismic Isolation of Nuclear Plants: A World Overview
The French were first to apply seismic isolation to the design of nuclear structures. Two large Pressurized Water Reactor plants (PWR) were isolated; the two unit Koeberg station in South...

Fracturing of Rock Using Expansive Soundless Chemical Demolition Agents
The theoretical principles of the action of expansive soundless chemical demolition agents are presented. The procedure for using these demolition agents are briefly outlined. Differences...

Comparative Performance of Two Pile Types
This paper reports on the pile driving and load bearing characteristics of the two pile types driven at a plant site in Sumatra, Indonesia. Nine prestressed concrete piles were driven...

Management of Fisheries in the State of Rio De Janeiro, Brazil
To improve the interdisciplinary knowledge and to subdivide the problem in bio-ecological sectors, international committees recommend the development of integrated evaluation groups. On...

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...

Computerized Operation of Water and Urban Networks: From Digital Mapping to Integrated Information Systems
Advances in computer hardware and software have provided the opportunity for development of powerful technical information systems (TIS) for municipal water supply and distribution services....

Field Measurement of Topography at a River Mouth
The authors have been measuring topography and cross section at the river mouth of the Nanakita River, in Japan. Changes of short-time scale, such as straightening of the river channel...

Suspended Sediment Regression Model on Mud Coasts
Two statistical models of the concentration of suspended sediment on mud coasts have been developed by using the stepwise regression method. The statistical analysis in this paper is based...

Suspended Sediment Model of Offshore Tin Mining
The three dimensional dispersion equation is integrated vertically to use in describing the suspension of silt from offshore tin mining. The resulting two dimensional equation includes...

River Training Works in Gezhouba Project on the Yangtze
A great number of research results of the river regime planning and river training work in Gezhouba Project on the Yangtze are described together with their application in the Project....

Sediment Yield and Mean Annual Discharge from Watersheds in the Indian Subcontinent
Measurements of sediment deposition in reservoirs located in the Indian subcontinent (India, Nepal, Pakistan) indicate that the rate of sedimentation is much higher than predicted during...

Boundary Conditions of Tidal Model at River Mouth
A small grid is required to schematize irregular shape of shoreline in the vicinity of river mouth which limits the modeling area to be small. Tidal records along the boundary show no...

Bank Protection at the Middle and Lower Yangtze
The Middle and Lower Yangtze runs through alluvial plains about 1800 km. There are mainly three types of river reaches: straight-slightly sinuous, meandering, and braided. This paper outlines...

Handling of Intake Bulkhead at King Talal Dam
During raising of King Talal Dam in Jordan in 1986, the existing intake wheel gate provided at the inlet of the project Low Level Outlet Works (LLOW) tunnel was found inadequate to withstand...

Debris Torrents in Nepal and Use of Reliability Engineering Concepts During Redesign of River Works
Debris torrents, generated by cloudbursts and by glacier lake outbursts, occur frequently in the Nepal Himalaya. A simple fault tree analysis is applied to the destruction of a diversion...

China's Ertan Hydroelectric Project
Ertan will be a major hydroelectric project on the Yalong River in China. The project consists of a 240 m high arch dam, two tunnel spillways, an overflow spillway, mid- and low-level...

Spillway Crest Development through Model Testing on Chenderoh Ambursen Dam
The Chenderoh Hydroelectric Project on the Perak River in Malaysia was placed in service in 1930. The hollow Ambursen dam was modified in 1944 by the additions of a concrete cap with flashboards....

New Martinsville Hydroelectric Project
The New Martinsville Hydroelectric Project consists of a dual bulb unit, 34 MW powerhouse constructed at an existing lock and dam navigation facility. The project was completed on budget...
