Designng to a Fault
Engineers designed a $30 million expansion of one of the Port of Los Angeles' busiest shipping terminals for a site sitting over the Palos Verdes Fault. Because closing the...
The Eccentric Entrance
Architects design irregularly shaped buildings to give their clients something different, and this creates problems for structural engineers, especially in earthquake zones. The Brinderson...
Massive Resistance
The recently completed structural reinforcement of the 95 year old landmark Salt Lake City & County building, and its 250 ft high central clocktower, is believed to be the first...
Real World Analysis
The structural concepts, seismic analysis and design of five recent highrise structures is presented in this paper. The paper deals with the problem of multistory buildings having Structural...
Seismic Design and Construction of Complex Civil Engineering Systems
This publication presents information about practices for planning, designing, and constructing civil engineering systems for mitigating earthquake effects. Concepts dealing with defining...
A Safe Skyscraper For the Seismic City
When completed in late 1989, the 73-story First International World Center will be the tallest office building in Los Angeles. The steel structure of the building was designed to be ductile...
Caissons Skirt a Tunnel
Exchange Place Center is a 490 ft, 30 story office tower built directly over the existing transportation hub in Jersey City, N.J., where trains and buses meet the PATH Tubes that carry...
Minipiles Mature in America
After being born more than 40 years ago in Europe, minipiles are maturing in the United States. Their distinctive feature is a relatively small diameter, rarely larger than 12 in. Constructing...
Making Use of Contaminated Soils
Using hot-mix asphalt (HMA) is one answer to contaminated soil. HMA plants can be modified to accept some contaminated soil�a boon not only to the generator of the soil but the asphalt...
Seismic Cutoff
The John Hart Dam, which is a 40-year old dam in British Vancouver, Canada, has been rehabilitated to meet current seismic codes. BC Hydro, the utility that owns the dam, conducted a study...
Load and Resistance Factor Design for Engineered Wood Construction
A Pre-Standard Report
The information contained in this pre-standard report is intended to provide guidance to writers of a load and resistance factor design (LRFD) specification for engineered wood construction....
Swedish Approach to Infiltration and Percolation Design
Design of infiltration and percolation facilities is similar to detention facilities. The storage volume of an infiltration basin being the ponding volume on top of the infiltration surface...
AASHTO Design Concepts
The AASHO Road Test of 1958-60 grew out of a need to quantify the effects of increasingly heavier axle and gross loads and varying wheel load configurations on the performance of this...
Concrete Pavement Rehabilitation Research Findings
A study to improve the procedures for evaluating and rehabilitating concrete pavements was undertaken in 1985. Field and analytical studies have facilitated a new knowledge and understanding...
Natural Vibrations of Cables in a Flowing Fluid
Cable segments are important components in a wide variety of marine operations. Their nonlinearities are primarily geometric as characterized by large displacements and load-dependent...
Overview of Factors Involved in the Mexico Earthquakes
The Mexico earthquakes provided many opportunities for learning. New knowledge has been obtained and continuing research will provide additional knowledge. The earthquakes have also demonstrated...
Damage Statistics of the September 19, 1985 Earthquake
Grupo ICA has participated in all stages of the actions and analysis of the effects of this quake aimed at taking advantage of this disastrous experience and has prepared a complete study...
Geotechnical Notes on the Effects of Mexico's 1985 Earthquakes
The present notes briefly describe the most relevant effects of the September 19 and 20, 1985 earthquakes on shallow and deep foundations used in Mexico City, which is located at about...
Analyses of Foundation Failures
During the earthquake of September 19th, 1985, many buildings tilted and underwent settlements, sometimes of very large magnitudes. This paper describes and analyzes these settlements....
Soil-Structure Interaction in Mexico City During the 1985 Earthquakes
The effects of the flexibility of the soil and the foundation on the seismic response of structures, by opposition to clear foundation failures, cannot be easily identified from a simple...
