In 'Engineering 21st Century Highways', we cannot expect to utilize only new technology and products developed and commercialized in this country. In the national...
Observations on Structural Pounding
In over 40% of the collapsed or severely damaged buildings in Mexico City, pounding of adjacent buildings occurred, and in at least 15% was the primary cause of collapse. The main objectives...
Emergency Regulations and the New Building Code
The 1942 Federal District Building Code was crude and overoptimistic. The 1957 earthquake prompted the drafting of emergency regulations, modern and more realistic. They evolved into the...
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...
Measuring Water-Dependency: A Puget Sound Example
Fostering water-dependent industry through allocation of urban shoreline sites is an important coastal management goal. But water-dependency is an elusive term to define operationally....
Temporary Structures in Construction Operations
Temporary works have a primary influence on the quality, safety, speed and profitability of all construction projects. They provide access, support and protection of a facility under construction....
A Safer Earthquake Design Approach
The Uniform Building Code earthquake code permits taking advantage of a frame's capacity to absorb energy at stresses beyond yield. Dropping that provision would save lives....
Coupled Implicit Simulation of Mobile-Bed Rivers
Numerical and physical deficiencies in existing computational codes for simulation of bed evolution in mobile-bed rivers have led the authors to propose a new approach. The new method...
Multiple Presence Reduction Factors for Bridges
