New Concrete and Asphalt Mixes on the Horizon
Significant research is currently 'in progress' which is intended to develop modified or new design methodologies that will result in improved pavement performance....
Building Bridges the Old Way
Cast-in-place concrete bridges built on falsework, particularly post-tensioned box girders, are California's dominant structure type. Factors which have led to the popularity...
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....
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...
Preliminary Dynamic Analyses of the Ministry of Agriculture Building
The Ministry of Agriculture building on Avenida San Antonio Abad was originally constructed as a 17 story reinforced concrete structure using a waffle slab system with interior reinforced...
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....
Behavior of Reinforced Concrete Framing Systems
On September 19, 1985, Mexico City was hit by what is believed to have been the most damaging earthquake in its recorded history. In this report, a ground motion recorded in the severely...
Repairing and Strengthening of Reinforced Concrete Buildings Damaged in the 1985 Mexico City Earthquake
This paper describes briefly the criteria and techniques used for the repairing and strengthening of reinforced concrete buildings damaged in Mexico City during the 1985 earthquakes. It...
Burying the Nuclear Past
The Uranium Mill Tailings Remedial Action Program involves reclaiming 24 tailings piles. The work is done in terms of Federal Legislation to prtect the environment and people from the...
The Road to Drained Pavements
In California, a fast-draining base course within the pavement structure is now the preferred design. For the first time, the 1987 edition of the California Highway Design Manual recommends...
Pressure Injected Footings in Piedmont Profiles
Comparatively little has been published on the behavior of pressure injected footings in the Piedmont residual soils and weathered rocks. It is the purpose of this paper to describe some...
Design of Breakwaters for Hurricane Wave Attack
The breakwaters protecting Port of Haina in the Dominican Republic have been repeatedly damaged by hurricane storm waves. Attempt to repair the destroyed portions have been largely unsuccessful....
Construction of Fisherman's Wharf Breakwater
The San Francisco District of the United States Army Corps of Engineers recently completed construction of a breakwater at Fisherman's Wharf. The construction, completed ahead...
Integrated Monolayer Flexible Revetment Technology for Coastal Protection
Fundamental considerations for flexible revetment design are given in some detail and the critical need for sound engineering in a total system design approach is strongly emphasized....
Global Issues?Local Responsibilites
This paper discusses the concrete, day-to-day benefits of international regulations, the specific roles that local officials and interest groups play in developing successful international...
Concrete Overlays Challenge Asphalt
When a pavement needs more than minor repair but not total replacement, bonded and unbonded concrete overlays and inlays are options to consider. The article describes four projects where...
The Chicago Lakefront Plan - 1986
Although Chicago is considered to have one of the world's most beautiful and also stable waterfronts, much of its shore protection is in imminent danger of failure. Nearly...
Armor Protection for Rubble Mound Breakwaters
A brief summary of past practices in breakwater armor system design is presented. The limitations of current design procedures for rubble mound breakwaters are discussed and improved methods...
