Stability Under Seismic Loading
This publication includes five papers that cover the p- ? effect on seismic structures with semi-rigid connections, the effect of panel zone deformations on the structural response behavior,...
Isolating Earthquakes
The Foothills Communities Law and Justice Center in Rancho Cucamonga, Calif., is the first U.S. building to rest on base isolators for protection against a possible earthquake of 8.3 Richter....
A Damage Function Using Structural Response Measurements
A new damage function is proposed that expresses seismic damage in terms of the range and number of cycles of plastic deflection experienced by a structure. This and other damage functions...
Damage Model for Buildings Subjected to Earthquakes
A model based on random vibration method is developed for assessing building damage to earthquakes. The damage of reinforced concrete structures is expressed as a linear combination of...
Seismic Analysis of Horse Creek Dam, Hudson, Colorado
On April 8, 1981, six days after a Richter magnitude 4. 0 earthquake, inspectors from the Colorado State Engineer's Office discovered a small crack in outboard side of Horse...
SRC Elevated Station Structures for New Bullet Trains
SRC Steelframe reinforced concrete structures were utilized on several station buildings for the Japanese National Railways bullet trains. This paper presents an outline of the dimensions...
Recent Developments in Mixed Steel-Concrete Systems
Mixed steel-concrete systems have emerged into a well established new system that can be used as readily as either steel or concrete systems for high-rise buildings. Mixed systems offer...
Design of Framed Steel Structures with Infill Reinforced Concrete Walls
It is a well-known fact that an infill shear wall in a frame acts as a compressive diagonal strut, giving strength and inflexibility to the frame. Recently the Architectural Institute...
Seismic Capacity Evaluation of SRC Buildings
The Japanese standard for seismic capacity evaluation of existing composite steel and reinforced concrete (SRC) buildings was introduced. As it developed, based on the previously established...
Structural Safety Studies
Structural engineers are most concerned with the safety aspect of structures. The primary objective of structural engineers is to produce structures which are satisfactory in meeting certain...
Performance of Cogoti Dam Under Seismic Loading
At the time of its completion in 1938, the 280 ft (85 m) high Cogoti concrete face rockfill dam was exceeded in height by only one other dam of its type in the world, Salt Springs Dam....
Seismic Analysis of Concrete Face Rockfill Dams
In this article, the observed behavior of existing rockfill dams during earthquakes is compared with published data regarding the estimated seismic performance of several recently designed...
Earthquake Experience Data on Power and Industrial Structures: Applications to Seismic Design and Evaluation
An extensive study was conducted to document the seismic performance of typical power plant and industrial structures in selected recent strong earthquakes and to correlate the performance...
Aseismic Capability Prediction from Failure Data
Forensic engineering evaluations of failures have produced a wealth of technical data. In this paper, evaluation of representative failure data from one practitioner provided relevant...
A Look at the New ACI Concrete Code
Building Code Requirements for Reinforced Concrete (ACI 318-83) is discussed in terms of three major changes: limitations on chlorides, especially in aggregates, that affect durability;...
Seismic Design of Underground Structures Southern California Metro Rail Project
The effect of earthquakes on underground structures is the imposition of an arbitrary deformation which cannot be changed by strengthening the structure. The structural design goal is...
Seismic Risk and Decision Analysis of Lifeline Systems
This paper provides general guidelines for performing lifeline seismic risk and decision analyses. Relevant input models are introduced as they support the performance of component and...
Retrofitting Lifeline Facilities: The Japanese Approach
A brief history of the prediction of a major earthquake in the Tokai Area of Japan is reviewed. Planning and mitigation incorporating all levels of government and the private sector is...
Seismic Design of Airport Control Towers
The paper describes state-of-the-art design in seismically active areas. It includes a review of current code design parameters and specific tower design criteria. Tower design examples...
Port of Seattle Seismic Waterfront Design
This paper describes the soil seismic design process, using the design developed for a concrete apron project at Terminal 20 as an illustration. Damage by the 1965 earthquake is described....
