The results of a study funded by the U.S. Geological Survey as part of the National Earthquake Hazards Reduction Program are presented. The first objective of this study was the development of a database for all 211 highway bridges along I-55 in the New Madrid region of southeastern Missouri. Profiles for five key dimension parameters (which are stored in the database) were developed, and the results for concrete highway bridges are presented. The second objective was to perform field ambient vibration analyses on 25 typical highway bridge spans along the I-55 corridor to determine the fundamental vertical and lateral frequencies of the bridge spans measured. These 25 spans included six reinforced concrete slab spans and two reinforced concrete box-girder spans. The third objective was to use these bridge frequency results in conjunction with the dimension parameters stored in the database to develop empirical formulas for estimating bridge fundamental natural frequencies. These formulas were applied to all 211 Interstate highway bridges in southeastern Missouri. Profiles for both fundamental vertical and lateral frequencies were then developed, and the results for concrete highway bridges are presented.

This paper presents the new seismic design specifications for highway bridges issued by the Ministry of Construction in February 1990. Revisions of the previous specifications were based on the damage characteristics of highway bridges that were developed after the recent earthquakes. The primary revised items include the seismic lateral force, evaluation of inertia force for design of substructures considering structural response, checking the bearing capacity of reinforced concrete piers for lateral load, and dynamic response analysis. Emphasis is placed on the background of the revisions introduced in the new seismic design specifications.

Objective: To analyze and cover the statistical data concerning the development and application of live load and relevant design standards by the example of Saint Petersburg bridge constructions. Methods: A comprehensive three-stage analysis of technical documentation on the operated reinforced concrete bridge constructions of the city was applied. Historical and technical review of norms and specifications of design, since the end of the 19th century was conducted. Systematization, statistical analysis and splitting into stages and groups were carried out. Results: The article presents the development of design standards and temporary loads of reinforced concrete highway bridges. The statistics is made on the basis of the depot of Saint Petersburg bridges. The latter is characterized by the increased esthetic, and difficult technical operation features. Classification of temporary loads on structures of Saint Petersburg since 1891 was carried out. The stages of occurrence and formation of circulating load norms were analyzed. A certain feature in regulation of requirements for urban bridges was singled out. Examples of the relevant objects were given. A number of conclusions concerning the evolution of design standards were made. Practical importance: Taking into account the specifi city of the large megalopolis, management of technical condition of bridge constructions in Saint Petersburg represents an extremely responsible and difficult task. Authentic, exact and relevant data on the history of design of facilities, circulating load (both design and current) is necessary for the solution of the task in question. Statistical analysis was carried out to apply operation of reinforced concrete bridge constructions in practice as the most mass transportation facilities of the city. From a practical point of view the data in question will make it possible to provide and support the set standard (design) levels of reliability, safety and durability of bridge constructions with a sufficient share of probability.
