The 1988 UBC Seismic Provisions for Steel Structures?An Overview
This paper will give the reader an introduction to the seismic design provisions for steel structures in the 1988 Uniform Building Code. Chapter 27 in the 1988 UBC now contains over ten...
Concrete Structures?1988 UBC Seismic Provisions
This paper discusses the special requirements in the 1988 edition of the Uniform Building Code concerning reinforced concrete structures resisting forces induced by earthquakes. The provisions...
1988 Provisions for Masonry Design
The 1988 Uniform Building Code has seen a significant change in the seismic design requirements, Chapter 23, for the design of structures subjected to earthquake loads. This paper discusses...
Historic Background of Seismic Construction in San Francisco
A seismic design and construction tradition has developed in California because of the unique experience with local earthquakes. After the 1906 earthquake and fire, building performance...
Equating Dynamic Analysis to Static Code Provisions
Building codes generally prescribe seismic design provisions that include a static lateral force procedure that can easily be combined with the gravity loads to design the structural elements....
Development of Inelastic Reduction Factors to Provide an Elastic Design Procedure
R factor values can only be rationally selected when they are based on in part nonlinear inelastic dynamic analyses of building system types. However, it is informative to discuss the...
1988 SEAOC and UBC Seismic Provisions
This paper highlights the major improvements to seismic design provisions incorporated in the 1988 Structural Engineers Association of California (SEAOC) 'Blue Book'...
Recent Developments in Testing Base Isolation Systems
One of these developments has been the ability to test large scale isolation systems using simulated seismic loads. These tests have not only proven the performance and reliability of...
Recent Developments in Isolation Hardware
Most isolation systems have at least two physical components: one specifically intended to add flexibility and the other to control the resulting deflections. However, other elements may...
Seismic Isolation of Nuclear Plants: A World Overview
The French were first to apply seismic isolation to the design of nuclear structures. Two large Pressurized Water Reactor plants (PWR) were isolated; the two unit Koeberg station in South...
Shake Table Testing of a Friction Pendulum Seismic Isolation System
Building models using the Friction Pendulum System (FPS) were tested on the shaking table at the Earthquake Engineering Research Center of the University of California, Berkeley. This...
Inelastic Seismic Design of Concrete Structures
This paper provides an overview of the state-of-the-art publication on the same subject under preparation by ASCE-ACI Committee 442's Ad Hoc Subcommittee on Inelastic Response...
Deformability of Reinforced Concrete Members
A large volume of test data has been evaluated to establish deformability of reinforced concrete beams, columns, and structural walls in the inelastic range. Experimentally observed deformation...
Structural Resistance of Slabs for Blast Loading
Results from a series of static tests on one-way reinforced concrete slabs are summarized. The slabs were loaded with a uniform pressure and tested to large deflections. Parameters varied...
Assessment of Transmission Line Foundations
Electric utilities are faced with the need to build new transmission lines or to upgrade existing lines to meet future demands. Because of economic constraints and the difficulty of obtaining...
Cracking the Fire Code
Local building codes specify fire resistance for members in buildings and other structures, and structural engineers select materials and assemblies that have passed a standard fire resistance...
The Church on Stilts
Christ Church Cathedral is an Anglican church situated in the heart of downtown Montreal. Constructed in 1859, it is a perfect example of English neogothic architecture, characterized...
Tension Leg Platform
a State of the Art Review
Prepared by the Task Group on Compliant Offshore Platforms of ASCE. This report considers the analysis and design of tension leg platforms (TLPs),...
Pressuremeter Evaluation of Glacial Till Bearing Capacity in Toronto Canada
Glacial tills were evaluated at three Toronto sites, using conventional methods, the pressuremeter and full scale caisson load tests. The geologic environment and specific subsurface conditions...
Foundation Engineering Constraints in Karst Terrane
Cavity-prone carbonate rocks are found in many Appalachian valleys and represent a poorly recognized hazard. This paper reviews the nature of the problem of founding above these Cambro-Ordovician...
