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...

Journal of Aerospace Engineering
The Journal of Aerospace Engineering promotes the implementation and development of space and aerospace technologies and their transfer to other civil engineering applications. Topics of interest include...

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...

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...

Seismic Design Criteria for Foundations on Control Piles
Control piles have been widely used in Mexico City for underpinning buildings with excessive settlements caused by the consolidation of the soft clay deposits, and as a foundation solution...

Performance Characteristics of Structures, 1985 Mexico City Earthquake
The 1985 Mexico City earthquake caused major damage to buildings, but not other structures, in the center of Mexico City, located approximately 400 km. from the epicenter. Due to soil...

R/C Frame Drift for 1985 Mexico Earthquake
This paper contains the results of a parametric study of the displacement response of multi-story reinforced concrete frames. Nonlinear lateral displacement responses were calculated for...

Evaluation of Performance of Concrete Buildings Damaged by the September 19, 1985 Mexico Earthquake
As a part of a general evaluation of the structural behavior of buildings during the 1985 earthquake in Mexico City, a detailed study of 8 damaged concrete buildings has been performed....

Performance of Steel Structures
A description of the various types of steel structures built in Mexico City is made, including comparisons of the older types of steel construction with more modern buildings. Performance...

Summary of the Effects of the 1985 Mexico Earthquake to Power and Industrial Facilities
A major industrial area and two power plants are near the epicenter of the Magnitude 8. 1 Mexico Earthquake of September 19, 1985. All investigated facilities are modern, generally well...

Seismic Rehabilitation: Why, When and How
Common methods of seismic rehabilitation are: repair of cracks, reconstruction of structural elements, addition of stiffening elements, and addition of dampers. A major consideration is...

Thoughts on a Different Approach to Seismic Design Codes
The aim of this paper is to show that some of the principles on which conventional structural design is based are not directly applicable to seismic design. Seismic design, and the corresponding...

Crossing A Freeway
The Washington State Convention and Trade Center in Seattle is being constructed on air rights spanning Interstate-5, adjacent to the seven acre Freeway Park that also spans the highway....

Transmission Structure Foundation Loads and Performance
Transmission line structures are subjected to unique loading conditions which for the majority of structures results in maximum loads which occur infrequently and act for only short periods...

Engineering Aspects of Point Versus Nonpoint Sources of Groundwater Pollution
Pollution of groundwater may occur due to a number of sources. These may be categorized into point and nonpoint sources of contamination. The purpose of this paper is to explore the issues...
